Mode System Patterns are not isolated-they are mutually dependent, and the pattern system binds their composition patterns together. A Software Architecture Model System is a collection of software architecture models. It includes guidance on implementation, combination, and actual use of models in software development. The main purpose of a software architecture model system is to support high-quality so

If the Apache configuration/apache Tomcat configuration file is not handled well, it will bring considerable hidden trouble to the site, directory Traversal vulnerability, will expose all the site's directories to the visitors, experienced developers or hacker from these directories to know the current site information, such as development language, Server system, site structure, and even some sensitive inf

[Big talk design model] -- Behavior Model Summary (one-to-many); big talk Design Model Based on the classification of the previous blog, this blog summarizes the one-to-many relationship: responsibility chain, intermediary, observer, iterator. In fact, there is nothing to do with these models, and there is nothing to compare. I just put them together. 1. Chain of

(According to the msdn webcast courses) This is a behavior-oriented design model that is widely used. Objects may often need different typesAlgorithm, But if the change is frequent, the type will become very fragile. As shown inCubeTake, take different cross sections, then its area calculation method will be different, need to use different algorithms. So, how can we design Algorithms Dynamically without changing the method during runtime? Deco

find a lot of problems, board rules need to build an object? Does the user interface need to build an object? Or when a property, the user is using abstract class description or entity class, the chessboard? Do you use form as a user interface? FOM program and how to design? Wait a minute..... And so we sweat the bite to finish. The next day the manager spoke. We need to add a stool to the design. That's not easy, then build a stool class, class stool. good. Who is to use the stool?

for processing the request has been theoretical, which is called the MPM: the Multi process model. The older Apache 1.3 model is represented by Prefork MPM, which is the default MPM for 2.0 on UNIX platforms. In this mode, there is a separate process that processes each request. However, if you compile Apache 2.0 with

interrupted, and the master process starts the new worker process quickly. Of course, the abnormal exit of the worker process must be a bug in the program, and an exception exit will cause all requests on the current worker to fail, but will not affect all requests, thus reducing the risk. Of course, there are many benefits, we can slowly experience. It says a lot about the Nginx process model, and next, let's look at how Nginx handles events. Someo

leakage may occur. 2. event The prefork and mpm methods are insufficient in extremely busy server applications. Although the HTTP Keepalive method can reduce the number of TCP connections and network load, the Keepalive must be bound to the service process or thread, This causes a busy server to consume all threads. Event MPM is a new model to solve this problem. It separates service processes from connections. The processing speed on the server is v

What are JSF, Facelets, and Apache Derby? The three technologies demonstrated in this article for WEB applications are JSF, Facelets, and java™database connectivity (jdbc™). JDBC is used to access data in the relational database Apache Derby. JSF is a WEB application framework for building the user interface (Interface,ui), Facelets is a presentation technology designed specifically for JSF.
