CONTROLLER

A controller for use in an object oriented environment connecting an information interface for a network user to a database. The controller optimises a memory usage in the environment by automatically generating a sub-object exist code used to ensure that all sub-objects of a released object are removed from memory. The controller also simulates a three tier client server model in which the class structure of the middle tier is retrieved from a database table allowing automatic amendments to the structure without the need for code modifications and testing reducing development time and costs.
