In ActivityInfo, a Database is where you store your data. Your Database serves as the central source of information for all your related projects and activities. All data are added, maintained and reported on from here.
Data Model
You can design Forms and Subforms to collect information (Records) from other users and you can add Folders to group your Forms. Your Database is also used to manage users and their permissions as well as Locks added for specific time periods to Forms and Subforms.
Finally, you can add Reports in your Database to create a complete package for the users added to it.
