摘要
本文在传统的三层架构基础上,为了保持数据库操作过程中的数据完整性将应用层分为业务原子层和业务控制层。在很好的保留原有多层架构优势的基础上实现用户界面访问底层数据的主要接口功能,将多个业务原子层的业务函数组装成一个完整的业务逻辑,形成一个业务流程供外界调用,可避免过去分层体系中多个不同原子操作过程中无法保持事务完整性的现象发生,同时可满足外部系统和系统业务规范的接口要求。
In this paper bases on the traditional three-layer architecture. In order to maintain data integrity in the process of the application layer, it divided the application layer into business atomic layer business control layer. On the basis of keeping the original multi-storey structure advantage, it implements the main interface functions of the user interface access to the underlying data. It makes a number of the business function in the business atomic layer assembled into a completely business logic to form a business process that call for the outside world. It can avoided phenomenon that in the past a number of different atomic operations unable to maintain the integrity of the Affairs, at the same time it also meet interface demand of the external system and system business criterion.
