Abstract
Abstract A method, apparatus, and article of manufacture for interfacing queryable datastore persistent objects to non-relational, non-object-oriented datastores. A computerized system in accordance with the principles of the present invention includes a "bridge" for receiving a request to access a datastore persistent object stored, for retrieving a logical unit of data from the external non-object-oriented datastore in response to the request, and for populating the datastore persistent object with the logical unit of data retrieved from the external non-object-oriented datastore, so that the logical unit of data is encapsulated within the datastore persistent object.

Claims Analysis
Total Claims: 30
Claim 1
Independent Claim
97 words
A computerized method for interfacing queryable datastore persistent objects to non-relational, non-object-oriented datastores, comprising the steps of: receiving a request to access a datastore persistent object stored in a memory of a computer; retrieving a logical unit of data from an external non-object-oriented datastore stored on a data storage device attached to a computer in response to the request; and populating the datastore persistent object with the logical unit of data retrieved from the external non-object-oriented datastore, so that the logical unit of data is encapsulated within the datastore persistent object in the memory of the computer.
Claim 2
Dependent Claim
97 words
A computerized method for interfacing queryable datastore persistent objects to non-relational, non-object-oriented datastores, comprising the steps of: receiving a request to access a datastore persistent object stored in a memory of a computer; retrieving a logical unit of data from an external non-object-oriented datastore stored on a data storage device attached to a computer in response to the request; and populating the datastore persistent object with the logical unit of data retrieved from the external non-object-oriented datastore, so that the logical unit of data is encapsulated within the datastore persistent object in the memory of the computer.
