which database is better in terms of speed the process of displaying data in an application?SQL Server 2000, MySQL, DB2. please write comment why you select that and how speed?thanks

Seeing as you're asking this on a MySQL forum then I guess the answer has to be MySQL. I have to ask - why are you asking such a question? Normally what affects the speed of displaying data in an application is how the original query was written. Once the query has executed and data is being fed back to the application then it makes little difference what RDBMS you're using. I can't see how your question makes any sense in the real world. Is this work or coursework?
