Some background: I want to develop a desktop application, with a SQL database as storage. There is only one user at one time connected to the database.
To make maintainance easier, I would like to seperate GUI from Busniss Logic. Thus, I thought using a DataModule (where the BL is implemented), for each Dialog.
My question:
Where is the proper place to insert a TClientDataset component? Directly in the Dialog or in the DataModule?
Personaly, I place TDataset-descendants always in a datamodule. Should you, at some point, decide to redesign your forms, you still have your datasets at your disposal. Sharing information between forms is then easier as well.
In general, keep your GUI and data seperate!
