A database can be defined as
a collection of coherent (logical), meaningful data. The phrase collection of
coherent data needs to have a point of reference to be understood. A simple
point of reference would be the example of a postal address, this would
generally contain:
A building name
A flat number in the
building
A road name
An area name
A City Name
A Pincode
To project on this further,
multiple addresses kept together in one place, such as an address book, could
be termed as a coherent collection of data. Thus the address book is a database and the postal addresses in the book, is the data that fills the database.
