Accumulated by bit --- Summary of niuyun News Publishing System

Recently, the learning status has always been good. Recently, after reading the niuyun news and publishing system, I looked at training program 6.0 and found that the role of the niuyun news publishing system is actually an idiom-to inspire others. This news publishing system basically involves the knowledge modules required for B/S Development (HTML, Asp.net, XML, JavaScript, CSS. DIV, JQuery, AJAX ). My learning from this small system will also be transferred from C/S to B/S. Of course, this small system will bring me far more than this.

 

I. Re-recognize the software development process.

Although I have learned UML, software engineering, and so on before, I have a preliminary understanding of system development. But when I do it myself, I often don't know how to start it. After watching this series of videos, I have a little understanding of the software engineering I have watched before. Requirement --> document --> prototype design (Phase 1) --> Database Design (Phase 2) --> write code (layer D --> layer B --> layer U ). At the same time, in the C/S phase, the problem of restructuring the data center charging system is easily solved with pleasure.

 

2. Update Old Knowledge

In fact, this is also one of my deepest feelings.

First of all, I have a better understanding of the three-tier architecture, how to layer, and how to classify it. (I can't bear to look directly at the B-tier of my Personal Edition ).

Secondly, we can't tell you how to build SQLHelper step by step without making a perfect explanation in the video. Before that, I wrote SQLHelper by myself, and there are still a lot of repeated code.

Again, I read about SQL server in the last summer and I felt like "Oh, I have read about stored procedures and triggers ", this time I felt like "Oh, the original stored procedure and the logpilot are such a thing ". In this series of videos, I started to use Join. I was not afraid of being tired when I thought about refactoring.

 

Iii. Motive Force behind discovery

Think about how to copy and paste the code again and again in the first day. It's really fearless (of course, this kind of spirit is quite good ). When constructing SQLHelper, each method actually has a bunch of duplicate code. Before that, I did not think about it (maybe but did not do it) to abstract the duplicates, in this way, the same code can be written three times less. However, the teachers in the video don't have to deal with it. Every place should do its best, whether it's repetitive code or the design of the U-layer interface, they should be patiently modified. At the same time, by modifying different data in CSS. Div, you can view the changes in the webpage layout and get a little familiar with some of these attributes. It does not give learners better resources, nor can they allow themselves to go further on the programming path.

 

4. Know yourself and know what you want to do

Does this title seem to be different from this article? In fact, I have a preliminary understanding of B/S development through this system, the next learning will also begin from exploring new knowledge to improving old knowledge. I think this small change may change our mindset in the next type of learning. We are not learning new knowledge, but asking old and old knowledge. This is not a bit of a feeling that "know yourself and know what you want to do. What I may know now is that the content in HTML, Asp.net, XML, JavaScript, CSS. DIV, JQuery, and AJAX is cool, but it is also cool.

 

In short, I did not stick to the materials in the source code in the study of Niuke news publishing system. Only by looking for pictures and designing styles can the system be completed step by step according to the instructor's explanation.
