| Abstract: | hat is an RTDB,why is an RTDB needed,what is the relation and difference betweena conventional database and a real-time system and what are its basic features? These ques-tions are discussed at length. An RTDBS is a database system with time limiting data andtransactions. Its basic features are that the data are not only with logic consistency, but alsowith external and interactive consistency ,and the transactions are with timing too. And allthese are closely related to transaction models. Various useful complex transaction modelsare described. |

| Keywords: | database real-time system real-time database timing limit real-time trans-action complex transaction model |
