-inclusive model diagram, but the module you are modeling or under the case of the model, as for all-inclusive business model diagram, to the model is relatively mature after the integration Just keep good communication with the associated model in the process of modeling, of course, this kind of communication can avoid as far as possible, after all, the more communication information, indicating the stronger module coupling, this may be the module division unreasonable signal, need vigilance, o

Hijack users' private message content (bypassing Cross-Domain Policy/bypass) with design defects of everyone) Don't go around during the design. Didn't I find that I ran back to the starting point for half a day? I said it was a bypass. In fact, I used the design vulnerability.Cross-origin error: Blocked a frame with o

Cookie Introduction First, we will give a brief introduction to the cookie to illustrate how to use ASP to maintain the cookie. Cookie is a small file stored in the client computer, which means that every time a user visits your site, you can secretly put a file containing the relevant information on its hard disk.

Design in the application development based on B/s, from the basic technical Division of labor is two large, one is the software display interface, the other is the program logic. In the time of the scripting language of n years ago, whether ASP, PHP or JSP, we basically are the two soft together. Although we are trying to do a lot of functions or include files to try to achieve software reuse, we still can't meet the changing needs of our users, main

Whether your project is using swing technology or not, I would say that swing is a well-designed Java package that is filled with the wisdom of the master.

Swing technology has been used in foreign countries, because of the free Java, easy to learn and the full trust of Java technology, a lot of companies early on the application of everything

, each object of the system should focus on the discrete abstraction in the problem domain. So ideally, an object would only do one thing. This also brings a lot of benefits in development: it provides reusability and maintainability, and is a good foundation for refactoring.So almost all design patterns are based on this basic design principle. The origin of the
