How the Grinch Stole SQL Server Performance
This session shows several common mistakes and inefficiencies that can be found in many production systems such as excessive code reuse in the database using the views and multi-statement functions and in the data access code; unnecessary joins and I/O operations in pagination queries; storage of multiple entities in the same tables using XML for entities-specific attributes; usage of the optional parameters in the where clause of the queries; and several others. The session explains the root-cause of performance issues those mistakes introduce and demonstrates how to properly address them in the code and database design.
