Versioning and Source Code Control

Recommended by 0 users

SQL Server 2014 and SQL Server Integration Services (SSIS) integrate with source control products such as Subversion (SVN) and Visual Studio Team System. SVN is an open-source control product commonly used on many types of development platforms. Given the open-source nature of the product, several people have written extensions and integration points into different tools, such as Visual Studio. Visual Studio Team System is part of Microsoft’s Team Foundation Server, a suite of SDLC management tools — which includes a source control engine.

Subversion (SVN)

SVN is an open-source product that you can download and install. The easiest version to work with on the Windows platform is from www.visualsvn.com because it includes a SVN server management UI. You can download and install the server repository VisualSVNServer from the site just mentioned. This section also uses a Visual Studio plug-in for SVN called AhnkSVN, which is available from http://ankhsvn.open.collab.net. This integrates Visual Studio with the SVN repository. In this section, you’ll create a project in SQL Server Data Tools (SSDT) that demonstrates integrated source control with SVN.

To begin, install VisualSVNServer and AhnkSVN from the sites just mentioned.

To configure SSIS source control integration with SVN, open the SQL Server Business Intelligence Development Studio. You don’t need to connect to an instance of SQL Server to configure integrated source control.

To configure SVN as your SSIS source control, click Tools Options. Click Source Control and select Plug-in Selection. Select “Ankh – Subversion Support for Visual Studio” for the Current source control plug-in, as shown in below screen shot.

Support for Visual Studio” for the Current source control plug-in

For the purposes of this example, use “AnkhSVN – Subversion Support for Visual Studio” from the Source Control Environment Settings dropdown list and use the source control default options (refer to below screen shot). This SVN walkthrough assumes that you have installed SVN server and AnkhSVN on your local machine.

  1. Open SQL Server Business Intelligence Development Studio. Because SSDT uses the Visual Studio Integrated Development Environment (IDE), opening SQL Server Business Intelligence Development Studio will open Visual Studio 2013.
  2. When the SSDT IDE opens, click File ⇒ New ⇒ Project to start a new project. Enter a project name in the New Project dialog. For now, do not check the Add to source control checkbox, as shown in below screen shot.
    do not check the Add to source control checkbox
  3. Click OK to proceed, and a new project is created in the SSDT IDE.
  4. Add the project to SVN by right-clicking the project name in Solution Explorer and selecting Add Selected Projects to Subversion.
  5. You will be prompted to choose the Subversion repository and folders.
    a. The Project Name is what will be named within the SVN repository.
    b. The Repository Url is the location of the Project within your SVN repository. Below screen shot shows a new folder created in the ProSSIS repository within SVN.
    a new folder created in the ProSSIS repository within SVN
    NOTE You will have to have a repository created to go through this exercise. This is done through the Visual SVN Server application.
  6. Select OK to add your project to the SVN repository.
  7. In the next screen, specify a log message, which is created as part of any operation with SVN so that changes can be documented, as shown in below screen shot. Click OK.
    which is created as part of any operation with SVN so that changes can be documented
  8. The final dialog asks if you would like to mark the project as managed by Subversion. Click Yes.

After successfully connecting the project to SVN, you will notice a few new indicators in Visual Studio that demonstrate the integration. Below screen shot shows the Solution Explorer on the right with a few indicators next to the files. The blue plus symbol indicates that a file is pending initial addition to the Subversion project. The Pending Changes window at the bottom shows all the operations that need to be committed to SVN. SVN uses a commit process to save all changes.

The project shown here has a few packages added for demonstration purposes. You can add any existing packages to your project to test the source control integration.

To complete the connection of the project with SVN, click the Commit button within the Pending Changes window. This will add all the files to the SVN repository. To confirm this, open the VisualSVN Server component from the Start All Programs menu. Drill into the local server repository and the folder you created for the project. You should now see all the files from the project listed in the details window (see below screen shot). You may need to rightclick on the Repository in Visual SVN Server and click “Refresh” to see the files.

In addition to the files being added to the SVN repository, note that the files shown in the Solution Explorer in Visual Studio now have a blue checkbox next to them (instead of a blue plus symbol). This indicates that the files have now been added to the SVN repository.

To test SVN integration with your new SSIS project, manually lock one of the packages in your project for editing by right-clicking the package in Solution Explorer and choosing Subversion ⇒ Lock, as shown in below screen shot.

When you lock a file for editing, you prevent other people from checking in any edits of the file until you have completed your edits. The Select Files to Lock dialog appears, as shown in below screen shot. You can enter a comment to identify why you are locking the package.

The Select Files to Lock dialog appears

After you edit and save the package, the file is displayed in the Pending Changes list, and it has updated icons in Solution Explorer to indicate both that it has been changed and that it is locked (see in below screen shot).

it has updated icons in Solution Explorer to indicate both that it has been changed and that it is locked

NOTE This is a good location for change control documentation references or meaningful notes. Although it may seem obvious what change you have made in the code, documenting the change will help you in the future if you need to roll back a change or remember what changes were made!

You can now commit your changes by clicking the Commit button in the Pending Changes window, and the packages will be checked in and unlocked for the next operation.

Like many source control tools, SVN comes with several valuable features for working in a team situation and for code and process management. One of those features is versioning.

Every check-in operation preserves the previous version, so the entire version history can be acted upon. below screen shot shows the version history of a file with the right-click context menu displayed. Older versions can be restored and compared with current versions, logs can be updated, and changes can be highlighted.

Now that you’ve taken a look at what a common open-source tool (SVN) can do in terms of source code management and team coordination, it’s time to look at an enterprise tool in the Microsoft technology stack. The next section provides a brief introduction to Microsoft’s source control server and client tools known collectively as Visual Studio Team System.

Team Foundation Server, Team System, and SSIS

When Visual Studio 2010 was released, Microsoft updated Team System and Team Foundation Server — a powerful enterprise software development life cycle suite and project management repository consisting of collaborative services, integrated functionality, and an extensible application programming interface (API). Team System seamlessly integrates software development, project management, testing, and source control into the IDE for Visual Studio 2013.

Using Team System with SSDT and SSIS requires that you have at least Visual Studio Team System 2010 on your network and have installed at least Team Explorer 2010 on your development machine. For the purposes of this SSIS Software Development Life Cycle Topicwe’ve installed TFS 2013 and Visual Studio 2013. Also keep in mind that in order to create Projects and Team Collections the version of TFS must match the version of Visual Studio that is being used. For instance, Visual Studio 2013 cannot create Projects and Team Collections in TFS 2010, but Visual Studio 2010 can.

  • Visual Studio Team System 2013 (VSTS) can be purchased for use, but if you would like to evaluate the software, Microsoft provides a virtual machine that you can download and used for a period of time. Trial versions are available for both virtual PC and Hyper-V images and can be found at http://download.microsoft.com. Search for VSTS 2013 Trial on the Microsoft download page, and the results will include both virtual machines that can be used for testing. The examples in this section use the same trial version of VSTS.
  • Visual Studio Team Explorer 2013 is the client tool that integrates with Visual Studio and allows you to connect to the Team System server and explore the development items and work with the source control environment built into VSTS. The source control used by VSTS is a robust source control environment. You can search for and download Visual Studio Team Explorer from http://download.microsoft.com.

After satisfying the preceding requirements, follow these steps to use the VSTS source control. In the next section, you will also see how to create bug tracking tickets and work items in the VSTS Team Explorer.

  1. To configure Team Foundation Server as your SSIS source control, open SSDT (or close any existing open projects) and click Tools Options. Choose Source Control and select Visual Studio Team Foundation Server. Expand the Source Control node for detailed configuration, as shown in below screen shot.
    Expand the Source Control node for detailed configuration
    This section discusses the relationship between Team System and SQL Server Integration Services. The walkthrough is shown using SQL Server Data Tools (SSDT). If the SQL Server 2014 client tools are installed or Visual Studio 2013 is installed, opening SSDT will open Visual Studio 2013. If Team System is specified as the source controller for either environment, the environment, upon opening, will attempt to connect to a Team Foundation Server
  2. Once Visual Studio 2013 is configured to use Visual Studio Team Foundation Server as the source control, press Ctrl+\, Ctrl+M, or click the Team Explorer tab to view the Team System properties (or choose Team Explorer under the View menu).
  3. In the Team Explorer window, click the “Select Team Projects…” link to connect to the Team System server.
  4. Click the “Servers…” button as shown in Below first screen shot to browse for a Team Foundation Server. Alternatively, any Team Foundation Server that has already been added will be available to select from the dropdown list. In the Add/Remove Team Foundation Server dialog, click the “Add” button to add a new server. Below second screen shot shows the name of the trial version server to be added to the list
    to browse for a Team Foundation Server
    the name of the trial version server to be added to the list
  5. After adding the server (you will be prompted to log in using the credentials provided with the VSTS trial), close the server list dialog and choose the new server from the dropdown list. Click OK to save your server selection changes.
  6. Once you have connected to the Team Foundation Server, open the Team Explorer panel, click the “Connect” icon and then click the “Create Team Project…” link to launch the New Team Project Wizard. Enter a name (such as SSIS VSTS Project) and an optional description for the new Team Project, and then click the “Next” button to continue.
  7. Select a Process Template on the next step as shown in Figure 17-14, and then click the “Next” button to continue.

  8. Select a version control system on the next step, as shown in below screen shot, and then click the “Next” button to continue.
    version control system,then click the “Next” button to continue
  9. The final step of the wizard presents a brief summary of the Team Project’s settings, and a new Team Project will be defined according to the specified configurations. Creation status is indicated by a progress bar as setup scripts are executed. If all goes as expected, the wizard will display a Team Project Created dialog, as shown in below screen shot.
    If all goes as expected, the wizard will display a Team Project Created dialog

NOTE At this point, you have created a Team Project container for your SSIS projects. A Team Project is similar to a Visual Studio solution in that you can add several SSIS projects (or any other type of project) to it.

NOTE “Why create a Team Project?” you ask. The short answer is because the practice of database development is changing. Team development is becoming practical, even required, for DBAs in software shops of all sizes. It is no longer confined to the enterprise with dozens or hundreds of developers.

Team System provides a mechanism for DBAs to utilize team-based methodologies, perhaps for the first time. The Team Project is the heart of Team System’s framework for the database developer. Below screen shot shows the Visual Studio Team Project and all the containers of objects that can be created in the Team Project (such as Work Items, Documents, Reports, and Builds).

MSF Agile and SSIS

MSF Agile is an iterative methodology template included with Team System. In a typical agile software project, a time- and scope-limited project — called an iteration — is defined by collaboration with the customer. Deliverables are established, but they may be de-scoped in the interests of delivering a completed feature-set at the end of the iteration. An important aspect of agile iterations is that features slip, but timelines do not. In other words, if the team realizes that all features cannot be developed to completion during the time allotted, the time is not extended, and features that cannot be developed to completion are removed from the feature-set.

NOTE Agile methodologies are very suitable to SSIS and BI development projects because they allow more flexibility; changes can be readily adopted to provide an end solution that is suited to the user’s needs.

No one uses a single methodology alone. There are facets of waterfall thinking in any iterative project. In practice, your methodology is a function of the constraints of the development environment imposed by regulatory concerns, personal style, and results.

Once an MSF Agile Team Project hierarchy has been successfully created, the following subitems are available under the project in Team Explorer (refer to above screen shot):

  • Work Items
  • Documents
  • Reports
  • Team Builds
  • Source Control

The next sections cover what’s available to you in each of these subitems.

Work Items

In MSF Agile projects, work items consist of tasks, bugs, scenarios, and Quality of Service (QoS) requirements.

  • Bugs are self-explanatory — they are deficiencies or defects in the code or performance of the application.
  • Scenarios map to requirements and are akin to use cases in practice.
  • Quality of Service (QoS) requirements include acceptable performance under attack or stress. QoS includes scalability and security.
  • Tasks are a catchall category for work items that includes features yet to be developed.

To create a work item, right-click the Work Item folder, select Add Work Item, and choose one of the work item types. Below screen shot shows the work item Bug template, which enables bugs to be tracked and handled for your SSIS project.

shows the work item Bug template, which enables bugs to be tracked and handled for your SSIS project


The MSF Agile template includes several document templates to get you started with project documentation. Included are the following:

  • Development: Microsoft Project templates for development and testing efforts
  • Process Guidance: An HTML document that describes the MSF Agile process
  • Project Management: An Excel template containing a project “to do” list and an issues and triage spreadsheet
  • Requirements: Listing requirements for validation scenarios and a Quality of Service (QoS) Requirements list
  • Security: Document sample defining the security plan for functional areas in the solution
  • Shared Documents: A repository for miscellaneous project documents Test: Test plans for unit and integration testing


The MSF Agile template contains several built-in Reporting Services project status reports. These reports are accessible directly from Reporting Services or from the Project Portal (SharePoint Portal Services) website.

The Reporting Services home page contains links to several reports grouped by report type, as shown in below screen shot.

A few examples of valuable reports include:

  • Capacity Chart with Work Assigned gives a snapshot of the capacity of the amount of work that can be performed given the current team and the development velocity.
  • Burn Rate Chart shows the amount of work that can’t be performed given the number of hours left and the current trend of work velocity. This report shows hours completed, hours remaining, ideal trend, and actual trend.
  • Remaining Work report shows the teams progress on a current iteration by highlighting the work completed versus the work remaining trended over time. The Remaining Work report is part of the larger reporting solution provided by the Project Portal.

Team Builds

A Team Build is the compilation of the code together to be used for deployment. For SSIS, this would be packages in your project that are deployed to the server. If you will be using the SSIS 2014 and deploying your packages to the SSIS Server, then you will be using the deployment functionality in Project Deployment Model in SSIS. This is covered in Administering SSIS Topic.

Source Control

Source control within Visual Studio Team System is very similar to the SVN functionality walked through earlier in the SSIS Software Development Life Cycle Topic. You are able to check items into the source control, revert to a prior version of a package, keep notes as to what was changed, and so on. The section “Version and Source Control with Team System” later in the SSIS Software Development Life Cycle Topic covers the VSTS source control features.

The Project Portal

The Project Portal is implemented in SharePoint Portal Services and contains several helpful portals, including the following:

  • Announcements
  • Shared documents and Wiki sites
  • Reports (Bug Rates, Builds, and Quality Indicators)

The Project Portal provides a nice interface for the development team, but project managers are the target audience. The Project Portal can also serve to inform business stakeholders of project status. To navigate to the Project Portal home page, right-click the Team Project in Team Explorer and click Show Project Portal. Below Screen shot shows an example of the Project Portal with one of the reports viewed.

Putting Team System to Work

In this section, you’ll create a small SSIS package to demonstrate some fundamental Team System features.

  1. Create a new SSIS project in SSDT by clicking File ⇒ New ⇒ Project. From the Project Types tree view, select Business Intelligence Projects. From the Templates list view, select Integration Services Project. Do not check the Add to Source Control checkbox. Enter SSIS VSTS Integration Example as the project name in the Name text box, as shown in Below screen shot.
    Enter SSIS VSTS Integration Example as the project name in the Name text box
  2. Click OK to create the new project. Drag a Data Flow Task onto the Control Flow workspace.
  3. Right-click in the Connection Managers tab and select New OLE DB Connection to add a database connection. Click the New button to create a new OLE DB Connection.
  4. Select your local server from the Server Name dropdown list. Configure the connection for Windows or SQL Server authentication. Select AdventureWorks as the database name. You can click the Test Connection button to test the connectivity configuration. Click OK to close the Connection Manager dialog, and OK again to continue.
  5. Double-click the Data Flow Task to edit it. Drag an OLE DB source onto the Data Flow workspace. Double-click the OLE DB source to edit it.
  6. In the OLE DB Source Editor window, select the AdventureWorks connection in the OLE DB Connection Manager dropdown list. Select Table or View in the Data Access Mode dropdown list. Select [Sales].
    [SalesOrderHeader] in the “Name of the table or the view” dropdown list. Click OK to continue.
  7. Drag an Aggregate Transformation onto the Data Flow workspace. Connect the output of the OLE DB source to the Aggregate Transformation by dragging the blue arrow from the source to the transformation. From the Available Input Columns table, select OrderDate and SubTotal. In the grid below, ensure that the operation for OrderDate is Group by, and the operation for SubTotal is Sum, as shown in Below screen shot.
    ensure that the operation for OrderDate is Group by, and the operation for SubTotal is Sum
  8. Click OK to close the Aggregate Transformation Editor.
  9. Drag an Excel Destination onto the Data Flow workspace and connect the Aggregate output to it. Double-click the Excel Destination to open the Excel Destination Editor. Click the New button beside the OLE DB Connection Manager dropdown list to create a new Excel connection object. Enter c:\SSIS_output.xlsx in the Excel file path text box. Click OK to continue.
  10. You can create an Excel spreadsheet in this step. If you enter the desired name of a spreadsheet that does not yet exist, the Excel Destination Editor will not be able to locate a worksheet name. In this case, the “No tables or views could be loaded” message will appear in the Name of Excel Worksheet dropdown list.
  11. To create a worksheet, click the New button beside the Name of the Excel Sheet dropdown list. A Create Table dialog will appear. Click OK to accept the defaults and create the worksheet and Excel workbook.
  12. Click Mappings in the Excel Destination Editor to configure column-todata mappings. Accept the defaults by clicking OK.
  13. Click File ⇒ Save All to save your work.

Now that you have created a simple SSIS package, you will use this package to test the Team System functionality with SSIS.

Version and Source Control with Team System

The objective in this section is to walk you through integrating your SSIS project and package with Team System source control and versioning functionality.

  1. To add your SSIS project to the Team Project, open Solution Explorer, right-click the project, and click Add Project to Source Control.
  2. The Add Solution SSIS VSTS Integration Example to Source Control dialog appears, containing a list of Team Projects. Select the SSIS VSTS Project you created earlier, as shown in below screen shot.
    Select the SSIS VSTS Project you created earlier
  3. Click OK to continue. You have successfully created a Team Project and an SSIS project. The Team Project contains version control information — even now.
  4. Click View Other Windows Pending Changes to view the current source control status for the SSIS project, as shown in below screen shot.
    to view the current source control status for the SSIS project
    The Change column indicates that the files are currently in an Add status. This means the files are not yet source-controlled but are ready to be added to source control.
  5. Click the Check In button to add the current SSIS VSTS Integration Example project to the SSIS VSTS Project’s source control. This clears the Pending Checkin list. Editing the SSIS VSTS Integration Example project will cause the affected files to reappear in the Pending Checkin list.
    NOTE Any change made to the SSIS VSTS Integration Example project is now tracked against the source-controlled version maintained by the SSIS VSTS Project. Seemingly insignificant changes count: For instance, moving any item in the Data Flow workspace is considered an edit to the package item and is tracked.
    The default behavior for source control in Visual Studio is that checked-in items are automatically checked out when edited.
  6. You can view the current status of all Team Projects on your Team Foundation Server in the Source Control Explorer, as shown in below screen shot. To access the Source Control Explorer, double-click Source Control in the Team Explorer or click View Other Windows Source Control Explorer.
    You can view the current status of all Team Projects on your Team Foundation Server in the Source Control Explorer

This next example implements a larger change to demonstrate practical source control management, before moving into some advanced source control functionality

  1. In your SSIS project, add an Execute SQL Task to the Control Flow workspace. Configure the task by setting the Connection Type to OLE DB, the Connection to your AdventureWorks connection, and the SQLSourceType to Direct input. Set the SQL Statement to the following:
    1. if not exists(select * from sysobjects where id =
    object_id(‘Log’) and
    ObjectProperty(id, ‘IsUserTable’) = 1)
    LogDateTime datetime NOT NULL,
    LogLocation VarChar(50) NOT NULL,
    LogEvent VarChar(50) NOT NULL,
    LogDetails VarChar(1000) NULL,
    LogCount Int NULL
    ) ON [Primary]
    (getdate()) FOR
    (LogLocation, LogEvent, LogDetails, LogCount)
    VALUES(‘SSISDemo’, ‘DataFlow’, ‘Completed’,’1st Run’)
  2. It is always a good practice to check your SQL before execution. Do so by clicking the Parse Query button, and correct the SQL if necessary. Then click OK to continue.
  3. Connect the Data Flow Task to the Execute SQL Task by dragging the output (green arrow) of the Data Flow Task over to the Execute SQL Task.
  4. Save your changes by clicking the Save button on the toolbar. You now have updated your SSIS project and saved the changes to disk, but you have not committed the changes to source control. You can verify this in the Pending Changes window by clicking View ⇒ Other Windows ⇒ Pending Changes.
  5. The Change column indicates that Package.dtsx is in an Edit status. This means that changes to the existing source-controlled Package.dtsx file have been detected. Click the Check In button to publish your changes to source control.

Shelving and Unshelving

Shelving is a concept used in Microsoft source control technology since the release of VSTS. It enables you to preserve a snapshot of the current source state on the server for later retrieval and resumed development. You can also shelve code and pass it to another developer as part of a workload reassignment. In automated nightly build environments, shelving provides a means to preserve semi-complete code in a source control system without fully checking it into the build.

  1. Shelving a package requires that you have a pending check-in. If no packages are pending a check-in, first make a change to the package such as moving the Data Flow Task. To shelve code, click the Shelve link at the top of the Pending Change panel. The Shelve dialog appears, as shown in below screen shot.
    The Shelve dialog
    The “Preserve pending changes locally” checkbox enables you to choose between rolling back or keeping the edits since the last source code checkin. Checking the checkbox will keep the changes. Unchecking the checkbox will roll changes back to the last source-controlled version.
    NOTE The rollback will effectively “undo” all changes — even changes saved to disk.
  2. Leave the “Preserve pending changes locally” checkbox checked, provide a Shelveset name, and click Shelve to proceed.

The shelving process stores the code changes for later use, and you or other developers on your team can resume the development process from the point of the original code check-in before the modified version was shelved. At some point you may need to go back and unshelve the code. This can be handled with the following steps, but before unshelving, you need to have all pending code checked in.

  1. To unshelve code, click the Actions link at the top of the Pending Changes dialog. Click the Find Shelvesets action. You should see the Shelveset you just created in the previous step.
  2. Right-click on the shelveset and select Unshelve. This will unshelve the changes.

Note that an administrator or the user who created the shelving can now delete the shelved files after the code is checked back in.

Unshelving code with conflicts will roll the project back to its state at the time of shelving. For this reason, you may wish to consider shelving your current version of the code prior to unshelving a previous version.

If you are prompted to reload objects in your Visual Studio project, respond by clicking Yes or Yes to All. Your current version will be rolled back to the shelve set version.


The capability to branch code provides a mechanism to preserve the current state of a SSIS project and modify it in some fashion. Think of it as driving a stake in the ground of a project by marking the status of the current change set as “good.” In other words, you’ve come to a point where all the SSIS packages are working together and checked in and you want to be able to identify this point for stability and have the opportunity to branch the code for some new development or to test some new approaches without affecting the main code.

To branch, open Source Control Explorer by clicking View Other Windows  Source Control Explorer. Right-click the project name you wish to branch and click Branching and Merging Branch from the context menu, which brings up the Branch dialog shown in below screen shot. Select a name for the branched project and enter it into the To text box. Note the option to lock the new branch — thus preserving it indefinitely from accidental modification. You can further secure the branched code by including the option to not create local working copies for the new branch.

brings up the Branch dialog


Merging is the inverse operation for branching. It involves recombining code that has been modified with a branch that has not been modified. A merge operation requires that the code has first been changed and checked-in. Follow these steps to merge two branches:

  1. To merge projects, open Source Control Explorer. Right-click the name of the branched project containing the changes and click Branching and Merging Merge.
  2. The project you right-clicked in the previous step should appear in the Source Branch text box of the Version Control Merge Wizard. Select the Target branch (the branch containing no changes) from the Target Branch dropdown. Note the options to merge all or selected changes from the Source branch into the Target branch. Click Next to proceed.
  3. The Source Control Merge Wizard enables users to select the version criteria during merge. The options are Latest Version (default), Workspace, Label, Date, and Change Set. Click Finish to proceed.

If the Version Control Merge Wizard encounters errors while attempting the merge, the Resolve Conflicts dialog is displayed. Click Auto-Merge All to attempt an automatic merge. Click Resolve to manually merge branches. When all conflicts have been resolved, the Resolve Conflicts dialog will reflect that.

NOTE Never merge the XML code within a package file from different versions. This could corrupt the file. Therefore, when merging projects, always merge the list of objects, not the files themselves.

Labeling (Striping) Source Versions

Labeling provides a means to mark (or “stripe”) a version of the code. Generally, labeling is the last step performed in a source-controlled version of code — marking the version as complete. Additional changes require a branch.

  1. To label a version, open Source Control Explorer. Right-click the project and click Advanced Apply Label. Enter a name for the Label and an optional comment. Click the Add button to select files or project(s) to be labeled. This will invoke the New Label dialog, as shown in below screen shot.
    Add button to select files or project(s) to be labeled. This will invoke the New Label dialog
  2. Click OK to complete labeling.

There has been much debate about when to shelve, branch, or label. To standardize your SSIS development process, use the following recommended advice:

  • Shelve: Use when your code is not code complete. In other words, if your code isn’t ready for the nightly or weekly build, shelve it for now.
  • Branch: Use when you need to add functionality and features to an application that can be considered complete in some form. Some shops will have you branch if the code can be successfully built; others insist on no branching unless the code can be labeled.
  • Label: Use when you wish to mark a version of the application as “complete.” In practice, labels are the version, for instance, “”
