•The run-time engine implements the control flow and package management infrastructure
•The data flow engine is a specialized, high performance engine that is exclusively dedicated to extracting, transforming, and loading data.
◦ Using Import and Export Wizard
◦ Using BIDS
Import/Export Data◦ Choose Data Source◦ Choose Destination◦ Specify the Table/Query◦ Edit Mapping◦ Save and Run package
SSIS Projects:◦ Data Sources◦ Data Source Views◦ SSIS Packages:
Control flow Tasks Loops, sequences and events Variables and scoping Precedence constraints
Connections Manager Data flow
Source and destination adapters Transformations Multiple sources with joins and unions Multiple destinations with splits and multicast
Data sources◦ A data source is a connection reference that you create
outside a package. ◦ A real-time reference to a data store connection, which
includes all tables and views in the data store.
Data source views◦ Provide a subset of data from a data source ◦ You can extend a data source view by adding calculated
columns that are populated by custom expressions, adding new relationships between tables, replacing tables in the data source view with queries, and adding related tables.
Control flow Manages flow of the package and perform other management tasks like logging ,checkpoint ,transaction handling etc.
Tasks◦ Tasks do the work in packages. The most important task is
the data flow task Containers
◦ Containers allow you to group together, or loop through, the tasks
Precedence constraints◦ Precedence constraints join tasks together
A connection manager is a logical representation of a connection
Different types of connection managers enable packages to connect to a variety of data sources and servers
Data flow◦ Is a engine dedicated to ETL process.
