Top 10 performance tuning tips for relational databasesAlthough newer relational databases and faster hardware run most SQL queries with a significantly smallresponse time, there is always room for improvement. This paper lists 10 tips that every developer/DBA shouldconsider when designing their database or writing SQL scripts. It also talks about some common mistakesdevelopers typically make and how to avoid them.Since most relational databases share same design concepts under their hood, this paper is not specific toany particular vendor.
The area of automatic selection of physical database design to optimize the performance of a relational database system based on a workload of SQL queries and updates has gained prominence in recent years. Major database vendors have released automated physical database design tools with the goal of reducing the total cost of ownership. An important assumption underlying these tools is that the workload is a set of SQL statements.
In this paper, we show that being able to treat the workload as a sequence, i.e., exploiting the ordering of statements can significantly broaden the usage of such tools. We present scenarios where exploiting sequence information in the workload is crucial for performance tuning. We also propose techniques for addressing the technical challenges arising from treating the workload as a sequence. We evaluate the effectiveness of our techniques through experiments on Microsoft SQL Server. Copyright © 2007 by the Association for Computing Machinery, Inc.
