If a "reasonable" notion of database consistency is to be supported (I.c. the database system is to enforce it automatically), there are bound to be" conflict" situations where one transaction comes into an access conflict against some other transaction. If await is to be avoided,some means of a negotiated settlement of the conflict must be provided, thereby dragging the users into the details of concurrency control.The single-database model is more appropriate-ate than the multiple-database model in an environment where it is difficult to determine in advance logical partitions of the database that correspond to work to be performed, and the users closely cooperate.
如果一个数据库一致的合理观念要得到支持(即数据库系统要自动实行这个观念)、一定会有矛盾的情形产生、在这种情形中一个业务与其它业务产生存取矛盾如果要避免等待,就必须提供某种协商解决矛盾的方法,从而迫使用户详细了解并行控制单一数据库模式在某一种环境中比多个数据库模式更恰当,在这个环境中,要事先确定与要执行的工作相适应的数据库的逻辑分割是很难的,同时用户们又紧密地合作在一起。
