It is the project'sAfter successful practice, Philip kruchten became the author of the RUP initiative.The proposal of agile processes directly affects the core thinking of architecture design. It is precisely because of the proposal of agil

Simulation Software Design of automatic batching system for Welding Electrode
Design Content
Welding rods are widely used in steel structures in construction and industry. A electrode can be divided into solder and solder. Solder is a steel rod with a specified material, length (about 400mm), and di
A friend mentioned that my blog is empty a few days ago. Indeed, there are some days in the garden. It's time to put something in it. Or Dudu. I have been idle for the past few days. I have recorded my reading notes and my own experiences.
McConnell said that if the design can achieve the following goals, it would be a very good design.

Minimum complexity
To put it simply, it is easy to understand. McC
How to use the robust diagram for preliminary design?The Admems method summarizes the 10 points of experience in the modeling of robust graphs, covering 4 aspects, including grammar, thinking, skill, and attentions.10 experiences in robust graph modeling.1. Abide by the modeling rules.You can understand the nature of the diagram by following 4 statements:1.1 Part
includes two aspects: 1, how to be more beautiful, 2, set which minimum function to meet the user's all requirements. The latter can be simply understood as "user experience design".We can follow the function of the description of a step-up deduction, followed by the whole process of thinking. First, we need to list the actions that the user may need, the problems they may encounter:1, the user every time to update the daily line will need to select

Input domain override methodThere are three main points: Intermediate value test (equivalent to Interior point), extreme value test (upper point in the boundary), special value test (business-related, according to software function)9. Output domain Override methodThe equivalence class and boundary value of the output domain are analyzed, the equivalent clas

Son: Dad, I want 1 GB of memory.
Dad: No, son. Not even for your birthday.
Today, the cost of large memory is sufficient. Google uses a large number of PCs to build clusters for data processing, and I have always felt that using a large memory PC can solve front-end and even intermediate load proble

Now the new Android yuan machine has 2 GB of memory. Do we need to rack our brains to save memory? Yes, it is a feature of high-end processors. Here we are talking about the resource shortage embedded system design method. Generally, the cost of the electronic products of single-chip microcomputer controllers is directly proportional to the memory, especially in the design of SOC chips. Before a large amoun

1. Module principle: use simple interfaces to Assemble simple components.
2. Clear principle: Clear is better than clever.
3. Combination Principle: Consider splicing and combination during design.
4. separation principle: the policy and mechanism are separated, and the interface is the same as the engine.

If the front end becomes overly complex, consider using the front-end framework.When it comes to frameworks, I'm actually referring to CSS frameworks, such as bootstrap,foundation, or even the larger framework of jquery, including more visualization modules and JavaScript plugi

environments, the "best method" is constantly changing and must be analyzed based on specific conditions..
Of course, there is another extreme opposite. I think that any method is not a good method, so I would rather follow the stream or talk about it later than pursue the universal value in this case. This will cause a lot of waste and mistakes, because when the "specific scenario" comes, without prior thinking and accumulation, I often feel unable to start. Therefore,For a specific environmen
