Appl. No.:

09/583705

Inventors:

Dwayne Smith - Louisville TX
James Mwaura - Irving TX

Assignee:

Sprint Communications Company, L.P. - Overland Park KS

International Classification:

G06F 1700

US Classification:

707103, 707 3, 707 4, 7071041, 707 9, 717108, 717116

Abstract:

The present invention relates to a computer software framework and method for accessing data from a datastore. The invention discloses a framework for accessing data from a datastore. The framework is comprised of a datatable comprising data retrieved from a datastore. A first class object, a second class object, and a third class object populated with columns of data from the datatable, and the second class object is referenced by the first class object and the third class object is referenced by the second class object. A hashtable is used to cache the first, second, and third class objects such that the first class object is stored as a key in the hashtable and the second and third class objects are the corresponding value of that key in the hashtable. The method for accessing data from a datastore comprises creating a datatable comprising data retrieved from a datastore. A first class object, a second class object, and a third class object are populated with columns of data from the datatable.

International Classification:

G06F017/00

US Classification:

707102, 707 2

Abstract:

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.

Abstract:

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.
