Data Read-Consistency During Update

Hi folks,

I have 3 tables of related data in SQL 2000/2005 that receive periodic adds/updates every 30 seconds.

I have enabled transactions on all updates, is anything else needed to ensure data consistency during reads in a high # of fetches per second situation?

Thanks,

john

Edit:

Clarification -- I just need the data to be correctly displayed to all users.

Hi,

I am not sure what do you mean by consistency. You may need to change transaction isolation level. Setting "serializable" level ensures complete consistency, but may impact performance of your server.

Thanks, that's what I was describing.
