Core Data allows developers to serialize data into SQLite for processing, similar in concept to ODBC when used with a non-SQL data source.
It can communicate with multiple databases such as: MySQL, PostgreSQL, ODBC, SQLite, Oracle, DB2, MS SQL Server, MaxDB, Visual FoxPro, FrontBase, InterBase, Firebird, Informix, LDAP, Netezza, SAP DB, Sybase, and generate code from them.
PowerBuilder offers native interfaces to all major databases, as well as ODBC and OLE-DB, in the Enterprise version.
It has a database capability built-in with ISAM and Associative Hashed Indexes, as well as ODBC, SQL, Oracle, sequential, random access, and XML files.
The database managers support access using many common distributed data access protocols and APIs including JDBC, OLE DB, and ODBC.
These extensions include, among others, ODBC (called the "crowning jewel of WOSA"), TAPI, WOSA/XFS, SAPI and MAPI, and their supporting services, as well as the abstraction of access to printers, modems, and networking services, which run identically over TCP/IP, IPX/SPX, and NetBEUI.
