Line 42: == Data Warehouse Architecture == The term Data Warehouse Architecture is primarily used to today to describe the overall structure of a [[Business Intelligence]] system. Other historical terms include [[Decision Support Systems]] (DSS), [[Management Information Systems]] (MIS), and others. The Data Warehouse Architecture describes the overall system from various perspectives such as Data, Process, and Infrastructure needed to communicate the structure, function and interrelationships of each component. The infrastructure or technology perspective details the various hardware and software products used to implement the distinct components of the overall system. The Data perspective typically diagrams the source and target data structures and aid the user in understanding what data assets are available and how they are related. The process perspective is primarily concerned with communicating the process and flow of data from the originating source system through the process of loading the data warehouse, and often the process that client products use to access and extract data from the warehouse. ▼ ▲The Data Warehouse Architecture describes the overall system from various perspectives such as Data, Process, and Infrastructure needed to communicate the structure, function and interrelationships of each component.
