Logical views of physical data stores

InfoSet:
Name for a particular type of InfoProvider: An InfoSet describes data sources that are usually defined as joins for ODS objects or InfoObjects (characteristics with master data). A time-dependent join or temporal join is a join that contains an InfoObject that is a time-dependent characteristic.

Virtual InfoCube:
A virtual InfoCube with services is an InfoCube that does not have its own physical data storage in BW. A user-defined function module is used as a data source. The properties of the data source can be defined more precisely using a number of options. Depending on these properties, the Data Manager provides services for converting the parameters and data.

MultiProvider:
A MultiProvider is a type of InfoProvider that combines data from a number of InfoProviders and makes it available for reporting purposes. The MultiProvider does not itself contain any data. Its data comes entirely from the InfoProviders on which it is based. These InfoProviders are connected to one another by a union operation.
InfoProviders and MultiProviders are the objects or views that are relevant for reporting.
