摘要
探讨了实时ＤＢ、主动ＤＢ的基本理论；提出了实时ＤＢ和主动ＤＢ的结合机制；
An investigation on the concept of real
time database and active database is made and the mechanism of the integration of the two
databases is proposed. The composition and the basic data structure of ARTs I the prototype of
active real time DBMS successfully developed on AT&Ts UNIX system V4.0 are described
and the function and realization technique for every subsystem of ARTs I are discussed. Four
distinguished features in ARTs I, namely, the theories of ADB, RTDB and MDB; the allocating
strategy of the transaction priority in combined static and dynamic states; the unified
scheduling mechanism of hard, soft, periodic, and aperiodic transactions; and a new active real
time descriptive language ARTDL, are given.
