A database-management system (DBMS) is a collection of interrelated data and a set of
programs to access those data. This is a collection of related data with an implicit
meaning and hence is a database. The collection of data, usually referred to as the
database, contains information relevant to an enterprise. The primary goal of a DBMS is
to provide a way to store and retrieve database information that is both convenient and
efficient. By data, we mean known facts that can be recorded and that have implicit
meaning. For example, consider the names, telephone numbers, and addresses of the
people you know. You may have recorded this data in an indexed address book, or you
may have stored it on a diskette, using a personal computer and software such as DBASE
IV or V, Microsoft ACCESS, or EXCEL. A datum – a unit of data – is a symbol or a set
of symbols which is used to represent something. This relationship between symbols and
what they represent is the essence of what we mean by information. Hence, information
is interpreted data – data supplied with semantics. Knowledge refers to the practical use
of information. While information can be transported, stored or shared without many
difficulties the same can not be said about knowledge. Knowledge necessarily involves a
personal experience. Referring back to the scientific experiment, a third person reading
the results will have information about it, while the person who conducted the experiment
personally will have knowledge about it.
