Hi,
MTS works perfect.
If you are using MS-SQL, better. It makes the development and performance very fast.
But on the other hand, you use Oracle, it will be a little hard, because the integration between MS x Oracle, works fine only with Oracle 8+, in my case I work with version 7.
If you don´t you Oracle 7, my friend, there´s no problem.
