Abstract: More and more grouped enterprises have expressed their requirements for distributed data management and multi-hierarchy decision support, which has brought up new challenges to data warehouse technology. To fulfill the requirements, a data warehouse solution is researched. Based on an analysis to shortages of traditional centralized data warehouse, the concept and architecture of a new solution, called as hybrid distributed data warehouses, are proposed. Then referring an ongoing project, some key techniques including meta-data distribution, data extraction, OLAP analysis, user management strategy, etc., are discussed in detail.

Key words: data warehouse, meta-data distribution, OLAP
