By who should be in charge of definition and the application that develop working shedding? Have 3 kinds of point of views commonly, namely 3 kinds of fixed position that we shed engine to the job:
1) the application that be in charge of define and developing the job to flow completely by actual technical personnel
I think this kind of viewpoint is equal to shed engine at needing the work, it suits the job with simple, little change to shed application only; If business logic and business are regular more complex, need oneself custom-built and corresponding application logic, and be ineffective live.
2) business personnel and technical personnel are united in wedlock
The job sheds a product to offer the interface that the graph changes, define business logic for business personnel; Technical personnel needs to finish specific applied logic.
3) business personnel is independent
This viewpoint thinks, should blend in the development of information system in working shedding engine, namely working shedding engine fulfils all functions.
At present with respect to home the circumstance looks, major pivotal business system sheds an ideology without applied job, namely the first viewpoint, this viewpoint has been proved to be incorrect; Software of abroad opening a source adopts the 2nd kind of point of view, because it cannot forecast the applied demand of all users; Domestic share company adopts the 3rd kind of point of view, but the solution that returns neither one to had been compared at present.
