If a web application is a project to develop team development, first, you should comply with the definition of software engineering development, determine the target, seek analysis, system design, etc. After a complete design, the web page designer, Web programmers, database programmers or more people should be in parallel. For example, a online bookstore, all database operations are completed by the database programmer, the user-oriented interface, that is, the web page, should be completed by the web designer, how the data is displayed and the client's interaction should be made by web programmer carry out. But these work will inevitably have a successful order, how to coordinate to implement parallel development? After these days, after reading MVC, there was an idea, perhaps close up to 100% of parallel development really realized. Web designers are responsible for designing files such as HTML, JS, and CSS to complete a static website, we can see the final effect; at the same time, database programmers will be packaged in all data operations to classes, here may be large segments SQL The statement, connection database operation, and PHP, Java code, PHP5 and Java are well supported object-oriented programming; some people may think that the work of the web programmer must wait until the first two start after completing it? In fact, it is not used. When the WEN programmer is forming Form, it is form, which is a form, and when it is a database, it is concerned about the class of the corresponding database operation, not a specific database operation, so as long as it is quickly developed analog database operation, You can make a Web programming. Quickly develop analog database operations is actually very simple, get data, as long as simple return data, very mechanical, data can be written directly in the class, because our purpose is just simulation. In this way, the 3 main force developed by the web application can develop a system parallel. Your own ideas, please enlighten me
