Answer:
SQL tuning and query optimization are essentially the same thing - tweaking the SQL code so that it uses less resources and/or processes faster. Query Analyzer is an app that's part of SQL Server which can assist in this endeavor by giving details about just how a given query is interpreted and processed.

SQL Tuning and Query Optimization are largely the same and in some regards quite different. Query Optimization will generally refer to programming practices like not using cursors, or the differenct between JOIN types. In my world, SQL tuning usually refers to hardware and server optimization; trying to get better IOPS from a given system; or setting up indexes and file partitioning. Query analysers will help with both, you can runa query and look at the execution plan generated by the SQL server and that will let you know where the bottleneck is. need help with SQL Tuning? give us a call http://www.nexusstrategiesllc.com
