Class and entity cache

In Progress Dynamics, a class or object type represents an inheritance mechanism for attributes that defines the behavior of the objects in that class. Entities in Dynamics define a logical schema in the Repository that corresponds to schema tables in the framework and application database. This class and entity information represents a large amount of data that typically does not change often, and, because of the object orientated nature of the framework, this information is expensive to access and organize at run time.

The class and entity cache adds an additional deployment step that precreates the data in a form that is readily usable at run time, and creates the data persistently so it can be deployed onto each client machine. This cache avoids the expense of constructing the information at run time, and it removes the need to transfer the data over the network at run time, thereby improving the overall performance of the application.
