Data is a collected part about a particular topic. As a database contains large amount of data that is all data about related topic as well as nearby data about a topic. Example, Google search engine has its own database which stores large amount of data. Whenever, the authors enter a query to search all the data related to that topic appears and then they select data according to their need. That's why it is true that databases are now-a-days becoming data rich but information poor.
