摘　　要：多个用户并发访问FT&MEDB中的同一数据,使并行访问量达到最大,同时保证每一个用户以一致的方式读取和修改数据。虽然采用封锁技术能够有效的解决,但是任何资源的独占都会有死锁的危险。对数据的封锁不仅会产生阻塞,在封锁技术应用不当的情况下,还会产生死锁。为此深入分析了封锁技术和FT&MEDB应用中产生的死锁原因,并给出了解决方案。The consumer is complicated by the same data in visiting FT ＆ MEDB much, makes parallel visit amounts reach a maximum, ensures that everyone consumer fetches and revises a data with consistent way at the same time. Though adopt monopolizing blockading a technology being able to solving, but any resource having effect, the city danger having dead lock. The blockage to the data may produce a blockage not only, may produce lock fast under blockading a technology applying improper condition. The dead lock cause blockading a technology and coming into being in FT ＆ MEDB application are analyzed, a scheme is given.
