1. The importance of demand analysisSoftware requirements refers to the user's expectations of the target software system in terms of function, behavior, performance, design constraints and so on.Typically, the software lifecycle includes activities such as feasibility analysis and development planning, requirements analysis,
Most developers with the experience of the growth, will enter a management position (team leader, of course, Bo Master only graduated for six months, not the development team leader, just in advance to share to everyone), need to be responsible for software system design (System function design and database design).

The design phase includes four aspects: Data design, system structure design, process
We focus on what the system is doing, and in the design phase we will focus on the software implementation issues of the system, including architecture design, detailed design, user interface design and database design.As with modeling,

Because [GOF95] is the first of a book on software patterns and is one of the most popular books in oo design theory, some people often use the term design pattern to refer to any type of schema, design, or program implementati

The initial architecture design determines the survival of software products. "A good start is half the success ".
The initial architecture design is also the most difficult. We need to investigate the situation and technical characteristics of similar products and learn about the theoretical support and technical platform suppor

This article introduces two important qualities of software design:Transparency and controllability. The author
This article introduces some of the principles in software design, which are learned after long-term experience. Every programmer should understand them. I believe it will be of great help to everyone in the process of software design.
Don't repeat yourself (dry)Dry is the simplest rule and the easiest to understand.
A large project must be designed first, but must be designed first. Before design, the requirement analysis is required. Requirement analysis is to understand what users "do". Requirement Analysis includes understanding the functional and performance requirements. Only after understanding the user's needs can we design them again to ensure rework after the project is completed.
