There is almost nothing about details of SQL Server 7.0 that would help you improve performance. This book is really dissapointing. This 2nd edition still only covers 6.5 stuff. One good example is the books description of the physical storage of the TEXT data type as using a linked list of 2K pages. SQL Server 7.0 has many advanced features for storing this data type and uses a B-tree instead of a linked list. The author goes over many tuning details needed when using 6.5 failing to mention the vast improvements in 7.0 that have made most of the tuning parameters obsolete.
