4. Due to time this session cannot Report Authoring Microsoft SQL Server 2008 R2: What’s new in Reporting Services – Donald Farmer Report Builder 3 (tomorrow) – Andrew Fryer Security

5. Parameters and Filter From a users perspective, parameters and filters look the same Parameters restricts the data at the source Filters returns all of the data and filters in place Parameters and filters affected by caching and snapshot settings

6. Caching Caching is not enable by default Can be used to improve the performance of retrieving reports by storing a copy in the ReportServerTempDB Configured to set an expiry time for the cache Consider “pre heating” the oven using data driven subscriptions

7. Execution process for cached instances 1. Retrieves most up-to-date data and processes report 2. Creates intermediate report and stores intermediate result in the cache in ReportServerTempDB 3. Flags intermediate report as a cached instance 4. Renders report from cached instance 5. Later requests for the same report are retrieved from the cached copy

8. Snapshots Snapshot are created in advance of the user browsing Stored in the ReportServerDB and are persistent Can be used to create historical data

9. Execution process for snapshots  Creation of snapshot is scheduled for a specific point in time  Requests are satisfied by retrieving and rendering the snapshot  The intermediate report is created and the result is stored as a snapshot in the report server database

10. Demonstration Creating Parameters and Filters Creating Cache settings Creating Report snapshots

11. I need a report from.....yesterday Historical data provides a point in time copy of reports Impact on parameters and filters Control the number of reports stored BE AWARE – Reducing the number of reports stored will truncate the reports

12. Demonstration Creating Historical Reports

13. Subscriptions Standard Subscriptions User and Administrator driven Data Driven Subscription Administrator driven Requires the creation of a subscriber table Can be used to pre populate a cache
