Note that the following code is handwritten, only a small part is tested: the Service class is universal, it is a bit difficult. This layer is closely related to Business, but in the database era, what is less than a few databases, then Just put these operations in the BASE's service. Of course, because of common, in order to let Service know what domain you do, you can't specify, so add a InitBaseService method. If a service There are multiple tables to be worried, and the initXXxxService method is increasing. It is recommended that service is a thick particle size. It should contain a DAO operation of multiple functions similar to the table. When developing software, you should not expand this service class, Here if you use the "Adapter" design tool to do, the effect may be good.
