Metadata management based on Lifecycle for DW 2.0
Reiifa Zhang, Ding Pan · 2010
DW 2.0 was defined as the next-generation data warehouse architecture by Inmon. Metadata's importance and role in the DW 2.0 are recognized. The most important of DW 2.0 is the recognition of the lifecycle of data within the data warehouse. Base on the lifecycle of data and the decentralized metadata repository architecture, this paper developed a new Lifecycle Based Metadata Repository Architecture. And an implementation was done with the use of generic object model (GOM) to build the meta model in the new architecture.
