Abstract

UNIVERSAL METADATA REPOSITORY INTRODUCTION Disclosed is a generic but infinitely extensible database schema that has a data driven approach to creating and managing a metadata repository. Metadata is recognized as a key asset of the business and technical information environment however few organizations have been able to effectively and easily organize and manage it. Current metadata repositories are rigid, closed information stores that are data store and database schema specific to a vendor’s solution set requiring either a vendor specific approach to metadata management or specialized customization. The Universal Metadata Repository (UMR) addresses these short comings of past and current metadata stores or repositories by creating a generic but infinitely extensible database schema which has a data driven approach to creating and managing metadata. The UMR is based on an abstracted or generalized data model that is highly extensible and allowing the capturing of any type of metadata both common metadata such as Logical Data Model Entities and Attributes, Physical Database Tables and Columns and “newly discovered” Types of metadata without changing the underlying repository structure. This is done by adding rows/records to the repository to first define the metadata Type(s) generally and then adding rows/records about the specific instance information/data thus capturing these “new” Types of metadata.
