sas etl studio contains two data quality transformation templates in the Process Library tree:
These templates increase the value of data through data analysis and data cleansing.
To use the data quality transformation templates,
When the prerequisites have been met, the data quality transformations can be dragged into process flow diagrams.
The Create Match Code plug-in is a tabbed dialog box that
The match code can then be used to de-duplicate data or join data as part of the transformation step in defining the target table.
The Apply Lookup Standardization plug-in is a tabbed dialog box that
You can then apply the scheme to one of the source columns as part of the transformation step in defining the target table.
Metadata Import Wizard
The Metadata Import Wizard is an interface for importing metadata files that are compliant with the Common Warehouse Metamodel (CWM) standard.
By using the Import Wizard to import the metadata from a previously defined data model (source tables or target tables), you do not have to enter the metadata for each table individually. You simply reference a location for the model file, which was created by a third-party modeling tool.
The CWM standard for metadata was developed by Object Management Group (OMG).
The Metadata Export Wizard is an interface for exporting metadata from within SAS ETL Studio to third-party CWM-compliant applications.
The user has the ability to specify the path and the file to create from the export of the metadata.
Once the user completes the Metadata Exporter wizard, a confirmation window verifies all of the selections, the user has made for the export of the metadata. Upon exiting this window, the metadata is written to the external file that was specified in the wizard.
SAS ETL Studio enables you to create metadata objects that define sources, targets, and the transformations that connect them. These objects are saved to one or more metadata repositories.
The change management feature (or more specifically, metadata source control) enables multiple SAS ETL Studio users to work with the same metadata repository at the same time without overwriting each other’s changes.
Change management features in SAS ETL Studio include:
The change management pop-up menu is used to perform change management tasks. The change management pop-up menu becomes active when a metadata profile is opened in which the default repository is a project repository. One way to display this sub-menu is to open the Inventory tree, the Custom tree, or the Project tree, then right-click an object in the tree.
The following are valid items on the pop-up menu:
|Check Out||Active in the Inventory tree or the Custom tree. Copies the metadata for one or more objects from a change-managed repository into the project repository.
Locks the objects in the change-managed repository.
|Check-In Repository||Active when you select the project repository icon in the Project tree. Moves all metadata from the project repository to the appropriate change-managed repository.|
|Undo Checkout||Active in the Project tree. “Undoes” the check-out state of the selected object. After you complete this action, the object is removed from the project repository and is no longer checked out.|
|Destroy||Active for checked-out objects in the Project tree. The object is deleted from the project repository, and upon check in, it is also deleted from the appropriate change-managed repository. You cannot undo a Destroy operation. Make sure that the object to be destroyed is not required in any SAS ETL Studio job.|
|Fetch||Active in the Inventory tree or the Custom tree. Use to get a copy of a metadata object for testing purposes. The copied object is not checked out from the change-managed repository, so the original object is not locked. The copied object can be modified, but it cannot be checked in. Fetched items will remain in the project repository until they are deleted.|
|Add-to Project||Active in the Project tree. Displays the Check Out wizard, which copies the metadata for one or more objects from a change-managed repository into the project repository. Locks the objects in the change-managed repository.|
Active for some objects in the Inventory tree, the Custom tree, and the Project tree. Lists all change management transactions for the selected object.
After an object has been checked out by one person, it is locked so that it cannot be updated by another person until the object has been checked back in.
The only people who can change the metadata in a change-managed repository are
