scrum, eXtreme Programming (XP) and Rational Unified Process (RUP) all have specific application methods.A heavyweight software development process is more stable for large projects. Due to my limited understanding of RUP, I will not discuss it in depth. For XP, continuous integration, Pair programming, and test-driven developmentIs actually the earliest use of this Agile Methodology, Crisp's HenrikThe kniberg team has tried the combination of scrum
some enthusiastic learners think that they can better find a job (or be subconscious-driven) by understanding object-oriented skills ). So I gradually changed from active participation to silence on these topics. Because in the end, this discussion has not hit the essence and has no guiding significance.

Recently, I have a relatively accurate understanding of the refinement of various fields in software engineering that I understand. This understanding is somewhat different from the traditional software engineering concept. I will write it here and I will add it later.
Software Engineering is divided into software engineering process theory and software engineering methodology.
Software Engineering Process Theory is divided:
Software Engineering
into three stages: 6. electronic data processing (EDP) in 1970s and management information system (MIS) in the middle of 1980s) corresponding to the Decision Support System (DSS) and the Strategic Information System (SIS) that emerged in the early 1990s S, IT planning can also be divided into three stages.

It has often been asked how "design gives product character" and "How to determine which visual style is more appropriate" through analysis. I am very happy to encounter these problems, because it shows that more and more people are beginning to pay more attention to the higher level of design problems, not limited to the design skills, aesthetic and other superficial problems.
In the past six months, I am also studying brand design-related methods. One is because the discovery industry ha

After selling the network of excellence, I've been thinking about what is the Internet? What was the great pressure I was facing? Jinshan is only 20% to 30% growth, and the network of Excellence can achieve 100% growth. I was thinking, this thing seems wrong, I spent 80% of time things only 20% to 30% growth, the problem is where? How can we

For the first time, scholars such as Goldwasser have systematically expounded the idea of provable security, the encryption and signature scheme with provable security [44,48] is given, however, the proven security of the above scheme is at the cost of the serious sacrifice of efficiency, therefore, although the above scheme is of great significance in theory, it is not practical. In the 1993, the Bellare and Rogaway two scholars [49] formally p

They all emphasize that software development is the process of cooperation between people, so the successful software development process should make full use of people's advantages, and weaken human shortcomings, highlighting the role of people in the software development process [2].

What is the software? This is a difficult question to explain. Simply put, it's some logical computer code. But from another point of view, it also has many kinds of meanings and many kinds of puzzles. For example, is software a tool? What is the relationship between it and the human mind? Should he have a personality or even a life? What is the future of software? What is the relationship between software and human future?
Humans have been studying computer software for decades, but i

The error message directly indicates the database log locked, which implies that the database log may not have upt, so there is no need to worry about dbcc repair.

Is methodology and architecture mutually exclusive?
Some people think that software development practices and architecture are not repeated. This may be true in other environments, but it is not true in this topic. On the one hand, agile methods (such as XP) directly focus on design, rather than specifically agreeing to the idea of doing a lot of design (bduf) in advance. On the other hand, most SOA teams primarily focus on
difficult to grasp the object-oriented ideas. At present, there are various ideas that hold your hair up.I think thinking inJava (Java programming ideology) is useless. It tries to talk about OO programming ideology at the language level, which is very unsuccessful. It can be used as a language reference, but as a learning material for the OO ideology embodied in Java,It is wrong.OO programming is a methodology. If there is no Application Comparison
