A DBMS can be classified as either centralized or distributed. A centralized system manages a single database while distributed manages multiple databases. A component DBS in a DBMS may be centralized or distributed. A multiple DBS (MDBS) can be classified into two types depending on the autonomy of the component DBS as federated and non federated.
The database schema is the structure of a database described in a formal language supported typically by a relational database management system (RDBMS). The term "schema" refers to the organization of data as a blueprint of how the database is constructed (divided into database tables in the case of relational databases).
It is composed of multiple database files, all controlled by a central DBMS. The main differences between centralized and distributed databases arise due to their respective basic characteristics. Differences include but are not limited to: Centralized databases store data on a single CPU bound to a single certain physical/geographical location.
