what is best architecture software

This is the second article in the series of Web services architecture. Starting from the technical definition of Web services, we will discuss what Web services are. First, the author analyzes in detail the basic role of Web services as software components in the Internet environment from a technical point of view, sta

because the model and view must be strictly separated, this also makes it difficult to debug the application. Each component must be thoroughly tested before use. Once your components have been tested, you can reuse them without any scruples. In my personal experience, since we split an application into three parts, using MVC also means that you are going to manage more files than before, which is obvious. It seems that our workload has increased, bu

. Its definition is similar to that of SOA. However, the current SOA is already different because it depends on some updates that are based on the Extensible Markup Language (XML. You can use an XML-based language (Web Service Definition Language (WSDL) to describe an interface. The service has been transferred to a more dynamic and flexible interface system, the Interface Definition Language (IDL)

Many years ago, when I held the ASM/C ++ knife, I thought there was nothing I could not write.ProgramAs long as someone in the world can write it out, I can. But what? Writing out does not mean good maintenance, modification, and reuse. Therefore, we consider object-oriented design patterns and so on. The purpose is to abstract them, abstract complex programming models into simple models that are easy to un

What is the difference between ViewModel and View,model in MVVM mode?Model: Very simple, is the business logic-related data objects, usually from the database mapping, we can say that the database corresponding to the model.View: Also very simple, is the display of the user interface.Basically, most

Object Request Broker Architecture (CORBA), which has been around for a long time. Its definition is similar to that of SOA. However, the current SOA is already different because it depends on some updates that are based on the Extensible Markup Language (XML. You can use an XML-based language (Web Service Definition Language (WSDL) to describe an interface. T

Layer-3 structure explanation The layer-3 architecture adds an intermediate layer between the client and the database, also known as the component layer. Here The three-tier system does not refer to the three-tier physical systems, either simply placing three machines or the three-tier architecture. A B/S application is not only a three-tier

Volatile-modified variables do not allow the thread to cache and reorder internally.The collation rules will constrain the order of any thread that violates the rule invocation in the course of the operation, and the sorting problem revolves around the sequence of reading, writing, and assignment statements.3.

servers at the same time As an architecture designer, it is far from enough to understand only programming languages, design patterns, protocols, and various popular and unpopular frameworks. First, he needs to focus on value and how to create value for customers and enterprises. The sensitivity to user interests, market, and business models is extremely importa

responsible for the interpretation and execution of the code. When the JVM runs the program, its memory is used to store a lot of content, including bytecode, additional information extracted from the class file, and objects instantiated in the program, method parameters, return values, local variables, and computed intermediate results. The memory management of the JVM is divided into two parts: e

constraints, so can be arbitrarily modified at any time. Of course, this is a mistaken view. Like any mechanical system, software has design and architecture; it's not as flexible as it looks.However, the accelerated development of the business requires people to constantly modify the software. The old method of devel

What is the difference between FULLGC, MINORGC and MAGORGC?FULLGC, MINORGC, MAGORGC, and YOUNGGC are the Java garbage Processing mechanism (GC) nouns, which are very simple to differentiate: Laosheng is a garbage cleanup, known as FULLGC or MAGORGC. A new generation of garbage cleanup, known as YOUNGGC or MINORG
