currently we sucessfully developed our application in that scenario using basically UniDAC and his features like pooling and disconnected mode and OmniThread.
to resume, when a task needs to interact with the database we create the connection at runtime, make the request and then destroy it.
another thing to mention here is that currently we have our own ORM that works great in this scenario too. thanks to the complexity of the ORM at the moment we can dedicate the amount of time it requires, so basically our ORM library is getting obsolete by the pass of time.
so the question is, can we apply entitydac into this multithread structure of ours without any trouble?
