With the database and Data Access Layer in place, it is now time to move on to the Business Layer. As suggested earlier, the purpose of the Business Layer is to provide operations to the View layer. It makes use of the Data Access layer to communicate with the database. Whilst developing the Data Access layer, we already implemented part of the Business Layer, being the Business Objects. These Business Objects are essentially the glue between the Business and Data Access layer. The second part to implement in the Business Object layer is the Business Object Managers.
