Session Object

The Session object, is an object instance derived from the fdoSession class (or subclass) and represents the front door to the persistence engine services. It is used to make connections to databases, save and retrieve business objects, update database schema definitions, Select , Insert, Update and Delete records in the database, perform object and SQL queries, and so on.

The Session object is the public interface to all of the persistence and mapping services. Internal implementation of these services is done actually by a related group of specialized components that encapsulate each service and call specific functions in the C++ FLL library, all of them working in a very efficient an integrated way. Public properties and Methods from these objects are exposed in the fdoSession class as an interface, making the core of FDO a fully scalable and robust foundation and hiding all the complexities of such a powerful engine.

The following figure shows the fdoSession class objects hierarchy.
