Method and apparatus for sharing metadata between multiple data marts through object references
DCFirst Claim
1. A database system for storing data, comprising:
- a global repository containing metadata;
a shared folder residing within the global repository, wherein the shared folder contains metadata which is to be shared;
a first data mart linked to the global repository;
a reference residing within the first data mart, wherein the reference specifies a link to of the metadata in the shared folder of the global repository and a user accesses the metadata through the first data mart by using the reference to read the metadata residing in the shared folder.

Abstract
A method and system for accessing and sharing metadata amongst a number of data marts through the use of object referencing. A global repository is created. Shared folders containing metadata is contained in the global repository. Any number of data marts can be linked to the global repository. Stored within the folders of the linked data marts are references pointing to certain metadata stored in the shared folders of the global repository. Multiple data marts can reference the same metadata in the global repository. Thereby, the same metadata can be accessed, used, and shared by multiple users across different data marts, provided that they have been granted the proper authority. New metadata can be promoted from a linked data mart into the global repository so that it can be shared, and updates to shared metadata can be automatically propagated to all users referencing that metadata.

7. A method for sharing metadata between a plurality of databases, comprising the steps of:
-
creating a first database comprised of a global data mart repository for storing the metadata that is to be shared; creating a second database comprised of a data mart; linking the second database to the first database; creating a reference which specifies a link to where the metadata is stored in the first database; storing the reference in the second database; accessing the metadata by using the reference. - View Dependent Claims (8, 9, 10, 11, 12)
