摘要
提出了序列块模式和全局惟一标识符模式的EJB主键生成策略,给出了这两种模式的生成算法.采用这两种模式生成EJB的主键,可使EJB的应用更具有可移植性、可维护性和可靠性.
Sequence block pattern and UUID for EJB for EJB＇s primary key generation strategies are put forward and then the building algorithms of these two patterns are provided. By adopting these two stragegies, good primary key can be generated and EJB＇s application can be made more protable, scalable and reliable.
