Why do I keep getting prompted to compact the database when I open my model? What does this mean?
When you delete an item in your model, it isn't fully removed from the database (mainly due to the undo feature.) The "compact database" function will remove these old entries and save on disk space. Under Tools > Options > Global, you can choose to have the program automatically compact the database after open the model a certain number of times. This is why you encounter that prompt. In the CONNECT edition version go to the Tools tab and click the arrow in the lower right hand corner of the window. See the screen shot below.
