Database Architecture for Data Warehousing: An Evolutionary Approach

In recent years, data warehouses have reached a prominent position in the database field, especially in the database industry. There are many issues in common between data warehouses and other database fields such as federated databases; in our opinion this fact has not been explored in its entirety. In this paper, an integrated database architecture in which data warehouses are part of the database is put forward. Instead of having data warehouses built using a database, we propose to have data warehouses defined as part of the database architecture; this architecture is defined as an extension of a federated database architecture.
