Abstract
Abstract A method, apparatus, and article of manufacture for encapsulating data from non-object-oriented datastores as datastore persistent objects. A computerized system in accordance with the principles of the present invention includes a "bridge" for retrieving a logical unit of data from the external non-object-oriented datastore, for mapping the logical unit of data retrieved from the external datastore into a datastore persistent object, and for manipulating the mapped logical unit of data within the datastore persistent object using methods associated with the object.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
93 words
A computerized method for encapsulating data from non-object-oriented datastores as datastore persistent objects, comprising the steps of: retrieving a logical unit of data from an external non-object-oriented datastore stored on a data storage device attached to a computer; mapping the logical unit of data retrieved from the external datastore into a datastore persistent object in a memory of the computer, so that the logical unit of data is encapsulated within the datastore persistent object; and manipulating the mapped logical unit of data within the datastore persistent object using methods associated with the object.
Claim 2
Dependent Claim
93 words
A computerized method for encapsulating data from non-object-oriented datastores as datastore persistent objects, comprising the steps of: retrieving a logical unit of data from an external non-object-oriented datastore stored on a data storage device attached to a computer; mapping the logical unit of data retrieved from the external datastore into a datastore persistent object in a memory of the computer, so that the logical unit of data is encapsulated within the datastore persistent object; and manipulating the mapped logical unit of data within the datastore persistent object using methods associated with the object.
Claim 3
Dependent Claim
36 words
The method of claim 1, further comprising the step of selectively sharing the logical unit of data encapsulated by the datastore persistent object with other application programs depending on the characteristics of the external non-object-oriented datastore.
Claim 4
Dependent Claim
28 words
The method of claim 1, wherein the methods associated with the datastore persistent object comprise member functions for manipulating the logical units of data in an object-oriented environment.
Claim 5
Dependent Claim
23 words
The method of claim 3, wherein the member functions maintain an integrity of the logical unit of data within the datastore persistent object.
Claim 6
Dependent Claim
33 words
The method of claim 1, wherein the logical unit of data encapsulated within the datastore persistent object comprises a transient copy of the logical unit of data as stored in the external datastore.
Claim 7
Dependent Claim
21 words
The method of claim 5, wherein the datastore persistent object includes internal flags indicating a status for the datastore persistent object.
Claim 8
Dependent Claim
105 words
A computerized apparatus for encapsulating data from non-object-oriented datastores as datastore persistent objects, comprising: an external non-object-oriented datastore stored on a data storage device attached to a computer; and a bridge program, executed by a computer, for retrieving a logical unit of data from the external non-object-oriented datastore, for mapping the logical unit of data retrieved from the external datastore into a datastore persistent object in a memory of the computer, so that the logical unit of data is encapsulated within the datastore persistent object, and for manipulating the mapped logical unit of data within the datastore persistent object using methods associated with the object.
Claim 9
Dependent Claim
105 words
A computerized apparatus for encapsulating data from non-object-oriented datastores as datastore persistent objects, comprising: an external non-object-oriented datastore stored on a data storage device attached to a computer; and a bridge program, executed by a computer, for retrieving a logical unit of data from the external non-object-oriented datastore, for mapping the logical unit of data retrieved from the external datastore into a datastore persistent object in a memory of the computer, so that the logical unit of data is encapsulated within the datastore persistent object, and for manipulating the mapped logical unit of data within the datastore persistent object using methods associated with the object.
Claim 10
Dependent Claim
39 words
