C/S learning Summary

C/S learning Summary

After more than a month of hard work, the reconstructed IDC was finally available. It took a long time, but I learned a lot from it.

Let's talk about the C/S study. C/S has gone through the soft work documents, UML, C #, design mode, VB. NET video, three-tier, and the individual version of the data center charging system. The personal version of the data center billing system is a big summary of the previous learning. Practice all the things learned throughout the C/S learning process. I have a deeper understanding of knowledge.

Soft work document

Soft work documents are essential in our software development process. Make our software development follow the evidence to improve development efficiency. At the same time, it also provides information about software operation and maintenance, facilitating communication and understanding between managers, developers, operators and users. Make software development activities more scientific and effective.

UML

UML is a powerful, object-oriented modeling language for visual system analysis. Its models help developers better understand business processes and build more reliable, A more comprehensive system model. Everything in UML is actually for communication. It is wrong to first code and then fix it. It is correct to first design and then correct it. The UML diagram is designed to find errors first, and then code is programmed according to the diagram.

C #, design mode

C # is the second programming language after learning VB. It is also a pure object-oriented language. Through C # learning, you can understand the communication between languages. When learning the design model, we also use C # as an example to get a deeper understanding of C. Through the design model, we have a new understanding of software design. The software is designed not only to implement functions, but also to reuse code when the needs are changed or used elsewhere. Make our software easier to maintain and reduce coupling.

VB. NET

Through VB. NET learning, we have a global understanding of VB. NET. VB. NET is similar to VB. It is also the third programming language. With the foundation of VB, learning is not difficult. At the same time, VB. NET is also an object-oriented language. Through VB. NET learning, we have a deeper understanding of object-oriented languages.

Layer 3

The three layers are divided into the interface layer (U layer), business logic layer (B layer), and data access layer (D Layer ). Layer 3 enables us to focus only on one layer in the entire structure, which reduces the dependency between layers and facilitates the reuse of logic at each layer. Better reduces coupling. At the same time, we also have a deeper understanding of parameter transfer and object-oriented between processes.

Data center charging system for VB. NET

The last data center charging system was designed for the process. This data center charging system was designed for object-oriented development. There is a big difference. Object-Oriented Programming makes the system more convenient to maintain and makes it easier to add new functions. The current understanding of object-oriented is just a bit of a bit, and we will continue to learn. I also learned a lot about the database in this IDC. I felt very high about the views and stored procedures. Now it seems not that difficult. The data center was restructured with various designs, documents, and diagrams. I feel more professional.

 

In general, we still need to continue to practice, but it is impossible to look at it. We can only understand the surface. If we have never practiced it, we are still quite confused. After practice, you will encounter problems and then solve the problems. In this way, we will have a deeper understanding and a stronger grasp.
