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.
