SSIS (SQL Server Integration Services)

SSIS are 2 types
ETL Operations (Extracting Transform Load)
E- Extracting –> Getting data
T- Transform –> performing intermediate operations
L- Load –> Load to destination
DB <-> DB
DB <-> File
File <-> File

Administrative Tasks:

  • Taking backup of a data base
  • Sharing data base
  • History clean up
  • Transferring data base/ log/error msg etc…

Databases: Oracle, SQL server, Tara data etc..
Files: XML, Excel, Flat file. Raw file etc…

SSIS Architecture


There are 4 important components in SSIS ARCHITECTURE

  1. Object model
  2. SSIS runtime
  3. Integration services service
  4. Data flow task

SSIS Designer: It’s a native tool to create ‘IS’ packages and it components.
Object model: It is an application programming interface which connects and understands custom tools and components.
SSIS runtime: This is ‘CLR’ which saves the layout of the packages (.dtx) runs the packages and manages the package components.
Integration services service: This component helps us to store the packages in SQL server_database (MSDB), managing the packages and running the packages.

DATA FLOW TASK: 

To move the data between source to destination and perform different operations, data flow task is required.
It uses various “Inline buffers” while processing the data.
It uses a “data pipe line engine” to move the data from source to destination and to manager buffers.

Package and its Components

Package is on important component in SSIS Architecture.

  • It can be constructed through custom tools (or) native tools.
  • It performs all operations such as “ETL” and administrative task.
  • It uses various other components as part of its processing. Ex: Logging, event handling, package configuration etc.
  • Control flow task is mandatory for every package.
  • To move the data from source to destination data flow task requires.

ENGINES IN SSIS
–> SQL engine (generates plan to execute package)
–> Data pipe line engine (only inside data flow task)
