AUTOMATED ABSTRACT DATABASE GENERATION THROUGH EXISTING APPLICATION STATEMENT ANALYSIS
First Claim
1. A computer implemented method for automatically generating a data repository abstraction component describing, and used to access, data in a data repository, the method comprising:
- monitoring queries issued against the data repository by an application;
collecting, from the monitored queries, information regarding usage of the fields of the data repository;
identifying, from the collected usage information, a limited subset of one or more fields of the data repository accessed by the application; and
generating, for use in the data repository abstraction component, abstract representations for the limited subset of fields;
wherein the abstract representations logically model the respective limited subset of fields;
whereby the data repository abstraction component is customized on the basis of usage of the fields of the data repository.

Abstract
The present invention generally is directed to methods, articles of manufacture and systems for automatically generating abstract representations of a limited subset of data repository fields accessed by a particular application. The limited subset of fields may be identified by monitoring queries issued against the data repository by the application. The abstract representations may be grouped in a data repository abstraction (DRA) component that serves as a data definition framework allowing data from the fields to be accessed independent of the particular in which the data is physically represented in the data repository. By limiting the fields exposed to the application to the limited subset of fields actually accessed by the application, the DRA component, in effect, provides the application with a custom database tailored to its particular needs.

21. A data processing system, comprising:
-
a processor and memory;
a data repository;
an application suitable for querying the data repository; and
a data repository abstraction generator configured to generate a data repository abstraction component describing, and used to access, data in the data repository based on usage information collected by monitoring and parsing queries issued against the data repository by the application;
wherein the data repository abstraction generator is configured to generate a plurality of logical field specifications for a limited subset of fields of the data repository accessed by the application, as indicated by the monitored queries;
whereby the data repository abstraction is customized on the basis of how the application queries the data repository. - View Dependent Claims (22, 23, 24, 25, 26, 27)
