Abstract
Abstract A method, apparatus, and article of manufacture for querying a non-relational, non-object-oriented datastore using objected-oriented techniques. A computerized system in accordance with the principles of the present invention includes a "bridge" for receiving a query request to retrieve data from the external datastore, for parsing the query request according to a specified syntax, and for storing the parsed query request in a query object, wherein the query object is later accessed to direct the retrieval of data from the external datastore.

Claims Analysis
Total Claims: 30
Claim 1
Independent Claim
85 words
A computerized method for querying non-object-oriented datastores using object-oriented techniques, comprising the steps of: receiving a query request to retrieve data from an external non-object-oriented datastore stored on a data storage device attached to a computer; parsing the query request in a memory of the computer according to a specified syntax; and storing the parsed query request in a query object in the memory of the computer, wherein the query object is later accessed to direct the retrieval of data from the external non-object-oriented datastore.
Claim 2
Dependent Claim
85 words
A computerized method for querying non-object-oriented datastores using object-oriented techniques, comprising the steps of: receiving a query request to retrieve data from an external non-object-oriented datastore stored on a data storage device attached to a computer; parsing the query request in a memory of the computer according to a specified syntax; and storing the parsed query request in a query object in the memory of the computer, wherein the query object is later accessed to direct the retrieval of data from the external non-object-oriented datastore.
Claim 3
Dependent Claim
19 words
The method of claim 1, wherein the parsing step further comprises the step of syntactically verifying the query request.
Claim 4
Dependent Claim
21 words
The method of claim 1, wherein the parsing step further comprises the step of verifying an accessibility status of the data.
Claim 5
Dependent Claim
28 words
The method of claim 1, wherein the query request includes elements selected from a group comprising path selections, field selections, attribute constraints, and boolean combinations of attribute constraints.
Claim 6
Dependent Claim
28 words
The method of claim 4, wherein the path selections are selected from a group comprising hierarchically related collections of data objects and an individual collection of data objects.
Claim 7
Dependent Claim
23 words
The method of claim 1, wherein the parsing step further comprises the step of sorting the query request into a proper path sequence.
Claim 8
Dependent Claim
20 words
The method of claim 1, wherein the query object further comprises a parse table for storing the parsed query request.
Claim 9
Dependent Claim
24 words
The method of claim 1, wherein the parsing step further comprises the step of translating the query request into instructions for a datastore manager.
Claim 10
Dependent Claim
21 words
The method of claim 1, further comprising the step of modifying the query object in response to receiving additional query requests.
Claim 11
Dependent Claim
85 words
A computerized apparatus for querying non-object-oriented datastores using object-oriented techniques, 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 receiving a query request to retrieve data from the external non-object-oriented datastore, for parsing the query request according to a specified syntax, and for storing the parsed query request in a query object, wherein the query object is later accessed to direct the retrieval of data from the external non-object-oriented datastore.
Claim 12
Dependent Claim
85 words
A computerized apparatus for querying non-object-oriented datastores using object-oriented techniques, 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 receiving a query request to retrieve data from the external non-object-oriented datastore, for parsing the query request according to a specified syntax, and for storing the parsed query request in a query object, wherein the query object is later accessed to direct the retrieval of data from the external non-object-oriented datastore.
