I remember that the discipline of the initial methodology of the initial contact should be "software engineering", so I thought about such a problem, what is the difference between the two. In fact, it is important to point out that in the field of MIS discipline, it can also be divided into two types, namely the engineering school and behavior. It is very good to understand that the focus is different, that is to say that our concern is that the information system acts on an organization or the company's management level is the focus on the development of the information system. In all, I personally, I should be more important, but I always adhere to the technology is the foundation, and it is something that must be mastered. I always think that if you simply can't understand the principles and operational mechanisms of the entire system, how do you talk about the so-called management of information systems or even consult [consulting]. However, in the actual application of the information system, many things are not solved or explained from the technical level. In the decision support system [DSS], a case [case] is mentioned in a GDSS [Packet Decision Support System], the computer monitor on the round table needs to use the horizontal design, and it is clear that organization behavior, etc. The domain knowledge to explain this problem. Although it is not related to this, it is clear that it is possible to optimize the entire system.
The above is said a lot, then go back to the beginning of the problem. Can look at the definition information systems [IS], "An infomation system (IS) is an arrangement of people, data, processes, infomation presentation, and infomation technology that interact to support and improve day-to-day operations in a business as Well As Support The Problem-Solving and Decision-Making Needs Of Management and Users. It can be seen that a critical part is that "people" emphasizes the important factors of people. And I understand the software engineering, more should be purely a standardization of development from the level of the project. Personnel designed in an information system may include system owners, system users, system designers, system developers, and system analysts. Of course, these are the concepts that can only be on, in fact, may be responsible for multiple aspects or many people responsible for one aspect. People are difficult to get to work. For system analysts, his work is coordinating these people's work, comprehensive responsibility and ensuring that the entire system can develop and implement correctly and efficiently. So as a system analyst, he needs to be multifaceted quality and talent, including knowledge of IT [Information Technology], computer programming [programming] experience and expertise, knowledge, solve the problem, The ability to communicate communication, as well as some flexibility and adaptive combination of individuality, etc.
