Several shape of Information System are broadly used in a variety of System Models. With the rapid development of computer network, Information System users concern more about data sharing in networks. In conventional relational database, data consistency was controlled by consistency control mechanism when a data object is locked in a sharing mode, other transactions can only read it, but cannot update it. If the traditional consistency control method has been used yet, the system's concurrency will be inadequately influenced. So there are many new necessities for the consistency control and security in Mobile Real Time Distributed Database (MRTDDB). The problem not limited only to type of data (e.g. mobile or real-time databases).
