The SASEXFSD interface engine enables SAS users to access both FactSet data and FactSet sourced data that are provided by the FactSet OnDemand service (formerly known as FASTFetch). This service provides access to many FactSet data sources and to many other databases. This chapter focuses on accessing the FactSet Fundamentals database. For detailed descriptions of other databases that you can access, see the FactSet Online Assistant available from the FactSet workstation.
The SASEXFSD engine uses the LIBNAME statement to specify which factlet (provided by FactSet) to use to open a database and what parts of the database to access. Factlets are FactSet functions that combine business logic and data collection procedures. FactSet technology is capable of cross-referencing and providing efficient access to time series that handle a large amount of data.
