To conquer all disadvantages of document preparing framework, another framework called database framework is created. Every one of the records in the document preparing framework are known as tables in the database. The substance of documents shape records of the table. We can likewise characterize a mapping between any two related tables. We characterize a special key segment for every record known as essential key. In database, each of segment qualities are known as property and every line of data is known as record. In the database, every arrangement of data is put away as lines and segments. There no distinction in the information being put away.  Utilizing essential key, we can get to the information much speedier than record framework.  This aides in decreasing superfluous information stockpiling and speedier recovery of information. Be that as it may, it is not quite the same as the record framework by the way information is put away and got to in the database.
