A homogenous distributed real time replicated database system is a network of two or more DBMS that reside on one or more machines. A distributed system that connects two or more databases are Homogenous Distributed DataBase Systems (HDDBS) create different problems when accessing distributed and replicated databases. Particularly, access control and transaction management in HDDBS require different mechanism to monitor data retrieval and update to databases. Current trends in multi-tier client/server networks make DDBS an appropriated solution to provide access to and control over localized databases. This paper highlights the basic concepts underlying distributed database system including transaction management in HDRTDBS. Distributed DataBase Systems (DDBS) create different problems when accessing distributed and replicated databases.
