Adding Advanced Features to Packages

Integration Services includes many features that you can use to extend the functionality of Integration Services packages. After you have finished building a basic package, you may want to add other features that make the package more robust, flexible, and easier to troubleshoot.

You can add the following features to packages:

  • Logging that captures information about a package at run time, making it easier to troubleshoot package performance and failure.

  • Transactions that ensure data integrity by supporting commit and rollback when packages perform multiple operations.

  • Checkpoints that make it possible to restart a package from a point of failure, instead of rerunning the workflow for the complete package.

  • Variables that pass values to scripts, provide parameter values for SQL statements, or modify the evaluation results of expressions.

  • Expressions and property expressions that update values in columns and properties of packages and package objects.

  • Queries that data flow components, such as the Lookup transformation, use to create in-memory reference tables.

The following table lists topics related to advanced package features.
