Database Support
Harbour extends the Clipper Replaceable Database Drivers (RDD) approach. It offers multiple RDDs such as DBF, DBFNTX, DBFCDX, DBFDBT and DBFFPT. In Harbour multiple RDDs can be used in a single application, and new logical RDDs can be defined from combination of other RDDs. The RDD architecture allows for inheritance, so that a given RDD may extend the functionality of other existing RDD(s). Third-party RDDs, like RDDSQL, RDDSIX, RMDBFCDX, Advantage Database Server, and Mediator exemplify some of the RDD architecture features. DBFNTX implementation has almost same functionality of DBFCDX and RDDSIX. NETIO and LetoDB provide remote access over TCP protocol.
Harbour also offers ODBC support by means of an OOP syntax, and ADO support by means of OLE. MySQL, PostgreSQL, SQLite, Firebird, Oracle are examples of databases which Harbour can connect.
xBase technologies often is confused with a RDBMS software. Although this is true, xBase is more than a simple database system as the same time xBase languages using purely DBF can not provide full concept of a real RDBMS.

Famous quotes containing the word support:
“Universal suffrage should rest upon universal education. To this end, liberal and permanent provision should be made for the support of free schools by the State governments, and, if need be, supplemented by legitimate aid from national authority.”
—Rutherford Birchard Hayes (1822–1893)
