The present invention relates to a computer framework and method for a business component to retrieve data from a backend datastore using object technology. The invention discloses a method for isolating a business component from specific implementations of a datastore, including the steps of supplying a database wrapper; using the database wrapper to begin a database session; supplying a domain object factory; using the domain object factory to create a domain object; converting the domain object from a persistent state to a transient state; ending the database session; and returning the domain object to the business component. The invention further discloses a framework for isolating a business component from specific implementations of a datastore, comprising a database wrapper in communication with a business component; a domain object factory in communication with the database wrapper; a domain object in communication with the domain object factory; and a datastore in communication with the domain object.

Computer framework and method for isolating a business component from specific implementations of a datastore

The present invention discloses a method for enumerating data pages in a stateless, distributed computing environment. A user operating a uses interface calls a stateless application, which in turn invokes a stateful data structure to retrieve data from a datastore. Stateful data residing within the stateful data structure is converted to stateless data, and a display page comprising stateless data is returned to the user. Preferably, the stateless application and the stateful data structures are Enterprise JavaBeans (EJB) compliant session beans. In a preferred embodiment, a servlet generates the display page by retrieving the stateless data from the stateful session bean, the display page is returned to the user interface via a communication framework, and data is retrieved from the datastore via a persistence framework.
