In the previous article I talked about the front and back of the separation of some views, this view is from a macro point of view, no concrete landing to achieve, today I will continue the topic of the previous article, from the front-end of the architecture design point of view of the front-end separation of a specific implementation of the program and I originally conceived a great change, But the core i

Opening and closing principle OCP (Open for extension,closed for modification). The core idea of open and close principle is that an object is opened to expansion and closed to modification. In fact, the opening and closing principle means that changes to the class are made by adding code rather than altering the existing code. In other words, once the software developer writes out the code that can be run, it should not change it, but to ensure that it can continue to run, how to do this? Th

Web API application architecture design analysis (1), api Architecture Design Web API is an application interface framework that can build HTTP services to support a wider range of clients (including browsers, mobile phones, tablets, and other mobile devices). ASP. NET Web API is.. NET Framework. This article mainly in

and knowledge (I have never thought too well about the classification standards, so I said my own experience and knowledge), I divided data into two categories: landing data and not landing data. Landing data: persistent data, which is usually stored on a hard disk or another persistent storage device. For example: images, system logs, data displayed on the page, and data stored in the relational database, there must be a fixed carrier for landing data that will not disappear instantly.

Introduction to android Architecture Design and android Architecture Design So far, android development has no accepted or unified development framework on the network or in the community. Many frameworks are based on method encapsulation. Today, I am talking about my understanding of android development over the past

Three, in-depth rddThe Rdd itself is an abstract class with many specific implementations of subclasses: The RDD will be calculated based on partition: The default partitioner is as follows: The documentation for Hashpartitioner is described below: Another common type of partitioner is Rangepartitioner: The RDD needs to consider the memory policy in the persistence: Spark offers many storagelevel to choose from: At the same time,

XP emphasizes a simple design principle: the functions that can be implemented using arrays are never linked lists. In other agile methods, simple principles are repeatedly emphasized. In this chapter, we have a comprehensive understanding of simplicity. Context To what extent should the architecture be designed? Problem The software architecture is very complex,

mouth Chen indicates the well. (Photography: author) The relationship between software and human beings is the core issue that architects must face. It is also a problem that has occurred since the software entered the stage of history. Like this, the relationship between architecture and human beings has been the core issue that architects must face since building. British Prime Minister Churchill said that we constructed a building and t

Iteration is a life cycle model of software development. We can get a lot of benefits by applying iterative design in the design. Context In the software life cycle, how do we deal with the development of architecture design? Problem Architecture

, the biggest problem is how responsibilities are assigned. On the system architecture design of the biggest problem, in fact, is the allocation of responsibilities, allocation of reasonable, the implementation will be very flexible, the contrary will make the structure is very chaotic.The life cycle of software can be summarized into four basic processes, analysis, des
