With DBMS all data are saved in one place in database and it’s not duplicated. In DMBS the data redundancy can be controlled or reduced but is not removed completed. Sometime is necessary duplicating some data to communicate with tables each other by managing redundancy data it is possible to save space and increase performance when queries are needed to retrieve data.
