Extracts:

Extract 1 - SAP’s BW information model is based on the core building block of InfoObjects which are used to describe business processes and information requirements. They provide basis for setting up complex information models in multiple languages, currencies, units of measure, hierarchy, etc. The key elements in the SAP’s BW information model are:

Extract 2 - SAP’s BW is based on “Enhanced Star schema” or “Info Cubes” database design. This database design has a central database table, known as ‘Fact Table’ which is surrounded by associated dimension tables. These dimension tables contain references to the pointer tables that point to the master data tables which in turn contain Master data objects such as customer, material and destination country stored in BW as Info objects. An InfoObjects can contain single field definitions such as transaction data or complex Customer Master Data that hold attributes, hierarchy and customer texts that are stored in their own tables.

Extract 3 - SAP BW can be integrated with other SAP components based on application programming interface (API) service. It provides a framework to enable comprehensive data replication based on data extractors that encapsulate the application logic. Data Extractor fills the extract structure of data source with a data from data source and offers sophisticated handling of changes. In addition to supporting extractors, the service APIs also enable online access via RemoteCube technology and flexible staging for hierarchies. On the other hand SAP provides an open interface called Staging Business Application Programming Interface (BAPI) to extract data from non-SAP sources.
