SOA Short for Service Oriented Architecture, in fact, a collection of services with loose relationships on the smallest particle size network (A Collection of Services) -------- they can communicate with each other . Service, as its most basic unit, eliminating other people paying attention to the implementation of the service, on this level, it is much higher than the oo high ------ OO only reaches the method level, the service is some Column related methods and objects are connected in series, which make up service. You can make an alteration like this, you have to send a quick piece to Beijing, you don't go back to send this shipment ----- You have more important things to do, then You call the courier company, then they sent people to take the letters and record related information - Of course you have to pay. You don't have to worry about you, you don't have a big accident (such as war, big Size plague), this shipment will arrive on time. In the above case, send the simply this is a service, the phone is a way to get the service, the person who sent the company is the interface of the service, ----- Here are two A very important place, how is the service? 2 is the interface of the service. Now you have got the interface of the service, then you put the parameters to the interface --- Express, money, etc. related information. Then the whole process Don't worry, directly care about the results - send it to the express mail. For example, let's buy rice. How is the rice? How do you send it? These don't pay attention, pay attention is just return value ------- they send rice , Then pay. If you have to do it, you have to care, is it a loss? The above is a simple example - you may not be the same at different positions. If you are more advanced, your service will be more advanced --- Query specific services do not need you to do it, your secretary can complete, then your mission is more easily ----- Find the secretary directly, there is no need to tubercion. SOA thinking, I think technology will be treated by humanization, and some ideas or development in society will appear in technology. From the intrinsic disorder to process, to OO, to SO, these are The development of human beings can be reflected, ----- With the development of society, the original simple collection of foods, to the food, then go to the people's own placeholders, in a part of human bearing animals Others do additional things, social division of labor is more clear, producing certain specialized industries, providing specialized services. Is it IT's technology development not experienced similar processes? It can be speculated that if human lifestyle Change, it will definitely bring leap in the technical field! So I have a bold idea: any field, any industry, eventually can be abstract, and can be consistent with the development of human society.
