The Enterprise approach to Meta data begins with our Enterprise Common Data Framework. Each data element within a model will have an approved standard definition and attributes. This information will be available to the enterprise within the established Enterprise Meta data Repository (EMR). This repository will contain useful business and technical information such as the source system, any transformations (conversions, compilations, etc.) that may have occurred to the data, its downstream usage, business rules that have been applied, dependencies, security, update methodology, etc.
As additional common data models are considered to be added to the ECDF, the EMR will provide a plethora of information to help determine the validity of the selected data elements as potential enterprise standards.
The EMR will also maintain the data from the Enterprise Inventory discussed under the Data Model Management page. It will be the responsibility of each business area to assure input of all of their data elements for all future production IT systems developed or purchased. This will keep the EMR up-to-date.
Data contained within the Enterprise Meta data Repository will be available to individuals doing ad hoc or Enterprise Query/Reporting to assure that similarly defined data fields are being accessed when joining information from disparate systems.
