“In computer science, a database is a structured collection of records or data that is stored in a computer system so that a computer program or person using a query language can consult it to answer queries. The records retrieved in answer to queries are information that can be used to make decisions. The computer program used to manage and query a database is known as a database management system (DBMS).” (Wikipedia, retrieved 22:30, 12 September 2007 (MEST)).

The goal of this (future) article is threefold (for now):
