Can someone explain to me the difference in the two. What I am trying to accomplish is I have a Program that we run now that is changing to SQL, and will run off of MSDE, but I currently have Veritas running off of MSDE on my server. From what I understand MSDE can only handle one app is this correct??? I don't know a lot about MSDE OR SQL, just know that I want to run NAI EPO, Veritas, and my new program. My question is do I need to upgrade to SQL Server to be able to accomplish this, or will MSDE do this. thanks in advance
