Summary of Personal Edition room fee system

It took one months to complete a personal version of the system of the restructuring of the room, not the heart of the summary is a little relieved.

First of all, a year ago, the first knock on the computer room charge system, it is purely process-oriented, can realize the function can. The system was completed at the beginning. It is also a milestone in the improvement of class learning, pure hand-made. Carefully built. we have learned to analyze business processes, digest and assimilate the learning results of VB and database, improve the affinity of code, and cultivate interest in programming.

A year later, now experienced the second computer room charge system. I deeply appreciate the good intentions of teacher training program , we are in fact climbing a mountain, one step at a stage. in the first computer room charging system exposed problems to be resolved and intact. Let's say the code repeats itself. The system structure is bloated, the change is not easy and the potential risk and so on.

A classic three-layer architecture is used in refactoring to deepen the understanding of previous theoretical knowledge. from pure process-oriented to semi-oriented process, not only can realize the function, but also improve the performance, optimize the structure. Design your own database this time . Consider the three paradigms. Use views, stored procedures, and triggers. Put the previous theory study into practice.

Once thought those things were very tall, and now just so so!

SQL Helper optimizes the database additions and deletions, reduces the code repeatedly, do it once and for all.

This time also uses the design pattern, uses the template method realizes the combination query. Use abstract Factory + reflection + configuration files to enhance system flexibility and facilitate database replacement. The nomenclature is more standardized. The code gaze is also more professional. Also learn to use ea to draw UML diagrams and generate code and documentation, and be proficient in using software development tools such as SQL Server and Visual Studio.

When debugging, there is no longer fear of bugs. Already have a certain ability to solve this problem.

two times the computer room charge system, one year after the lapse. Every one of us can see our own harvest and progress. Not only is the table now technical. There is also the ability of thought and other aspects. The upcoming Third Co-operative edition of the computer room fee system will also be a leap forward to experience project cooperation. to specialization and professionalism. Tomorrow will be better! Let's cheer together!
