SOA and McDonald's

The founder of the McDonald's brand is Ray croke. With extraordinary business talents, He has transformed the little restaurant sold as a brother into the world's first fast food brand, and he has become one of the entrepreneurs in the United States and even the world.

It is said that apart from Crock, the one who bought the franchise from the McDonald's brothers, there was also a Dutch. The two are on a completely different business path: croke only runs McDonald's stores, while the money for beef processing and cattle raising is earned by others; the Dutch not only open McDonald's stores, in addition, the investment opened a beef processing factory, so that the money for beef processing also flows into their pockets. Later, they started a cattle farm. After many years, crook went through the whole world, while the Dutch kept 200 cows in a farm in the Netherlands.

The concept of SOA is service-oriented and focuses on the concept of service. Current software development process model, both the waterfall model and the RUP model have to go through such a cycle as requirement analysis, outline design, detailed design, coding structure, unit testing, integration testing, system testing, and acceptance testing. These process models are either demand-driven or case-driven. The quality and progress of subsequent tasks depend heavily on the quality and progress of the previous tasks, thus affecting the quality and progress of the entire software development process. The strong coupling between such progress is converted to loose coupling after the SOA model is used. ManyArticleIt has always been said that using Java and WSDL to implement loose coupling is only at the technical level. Prior to the publication of SOA, loosely coupling has been widely applied in many places. If the loose coupling is one of the characteristics of SOA, it is not only a technical loose coupling, but also a loose coupling between processes.

In the story above, the Dutch people seem to be the general object-oriented software engineering development process, from providing fast food services to customers, to beef processing plants, and then to yangniu factory. Croke is not concerned about service-oriented, and does not care about beef processing and cattle raising.
