hello, I am a user who is using MIDAS the first time. My biggest question for now is the Application Server which handles all communication to the Interbase server. Starting with my Application Server I made a provider for every table to access. I ran into a problem using more than about 35 providers (giving some strange error-messages). Later on I discovered that you can do the whole thing by using one provider and using Datarequest event to change SQL (in the client) to get the table you want. But: is this not more time-consuming than the first method and will it give me problems when I have a lot of users connecting to the Application Server (errors)? Please help me on this.

It is possible to use a second RDM but what does it mean for the number of connections to the datase and the amount of client-licenses needed?
