I have installed QC 9.0 in SQL server 2005, but Mercury says that they will give support for SQL server 2005 until they release the next patch. But we have to use SQL server 2005 for development. What i wanted to know is What type of data QC will pass to SQL server. Are we using SQL server as to store and retrieve the data, or QC will do other operation on the DB. If any one know the integration architecture between QC and DB please share with me.

I want to make sure that if i use SQL server 2005 for QC , there would not be any data loss in the future.
