Databases

Basic Idea. A database (DB) is a collection of data files, organized so that a database management system (DBMS) can be used to manage, manipulate, and ask questions about information in those files. Data independence means that DBMS software can be changed independently of data files manipulated by that software.

Used for what? You name it. Any time you have to keep track of lots of information, and you need to view data from different perspectives, ask different questions about it, select arbitrary subsets of it, or look for relationships among data.

Famous examples. dBase, Oracle, MS Access.

Pioneers in Data Bases: Charles Bachman (1973), Edgar Codd (1981), James Gray (1998)
