A RelationalDataBase extended to make it useful in the real world.

[RelationalDataBase]s proved very powerful but somewhat hard to use for mortals, leading to their extension. Typical extensions include:
# Procedural extensions to [SQL]. These lead to the current plathora of SQL variants--everyone extended SQL differently.
# Extensions to the relation structure to allow for variable sized fields, particularly for string data. These have much less impact than the procedural extensions to [SQL] and are largely implemented by making fields pointers to the data rather than the data itself.

Most real-world databases are [PostRelationalDataBase]s: [Oracle], [MySQL], [PostgreSQL], [Microsoft] [SQL] Server, Informix, Borland Interbase, [FireBird] and [IBM] [DB2].
