restrict the query to only those elements that are really needed. You can drop unnecessary tables and segments of criteria. Improper indexes You should review indexes that are created on tables. Keep in mind that indexes are optimal for querying but not optimal for modifying data. They become overhead on transactions.

You can do many things to improve this kind of system: Denormalization This is probably the most effective way to improve the system. SQL Server will have to query a smaller number of tables. You can create a redundant set of tables (one or more, depending on the subject) and periodically (for example, every hour or every day) transfer data from the normalized tables to it. An additional benefit is that readers and writers will not block each other. Limit the result set Most search engines on the Web limit the number of results that the user can return (for example, 200 or 500 records). Split results rather than limit result sets Users should be able to access records in batches (of, for example, 25 or 50 records). Chances are that the user will browse through only the first couple of pages. There is no need to serve the user with 5000 records that he or she will not review. Index An additional benefit of splitting tables to provide one table for data modification and another for querying is that the indexes you would need to create on the denormalized tables will not slow down data modification transactions. Stored procedures vs. ad hoc queries Because of the many performance and management reasons discussed earlier, in Reuse of Stored Procedure Execution Plans in 3, you should use precompiled objects such as stored procedures as much as you can. Often, you can significantly simplify a query by dynamically assembling it. When you reduce the number of tables and parameters, the query optimizer creates a better execution plan. Search types Good results can sometimes be achieved by using a little psychology. For example, users do not always need to do a Contains search on a string (like '%string%'). Most of the time, Begins with (like 'string%') and Match (='string') searches are sufficient. For the latter two, SQL Server

does not ignore the index. If you add a list box with Search types to the text box and make Begins With the default option, users will use it probably 90 percent of the time. SQL Server does a table scan only when users really need to scan the whole field. I will review in detail some of these options in an Asset database scenario.

Some web sites split the result set on a web server. The complete result set is transferred to the web server and components on it create HTML pages with links between them. There are several good reasons to use this technique. A farm of web servers can efficiently balance the load. There are solutions on the market that can be purchased and implemented rapidly. Unfortunately, network traffic between servers is not reduced and SQL Server has to grab and transfer much more than it should. I will not go into the details of how to implement such a solution (you ll need a different book for that).

Page Splitting Using a Temporary Table on the Database Server
The idea of this solution is to collect the complete recordset in a temporary table and then to send to the caller only a subset of records (for example, 25 records) to be displayed on the current page. In the following example, the query creates a temporary table that has an additional identity field. The second query returns records with identity values between the specified numbers. Initially, these numbers might be 1 and 25. The next time it is called, the client increases the values of the first and the last records to be displayed.
