Product specifications

The Data Access layer manages the conversion of data types exposed by network layers into Connection
Server data types, which are then mapped to data types exposed in data foundations.
This section provides conversion tables between generic network layer data types (JDBC and ODBC)
and data foundation data types. It also provides conversion tables for specific network layers such as
OLE DB, Oracle OCI, and Sybase CTL, and describes non-trivial conversions and exceptions for specific
databases, such as CSV files and SAP ERP systems.
