Recently, I have a internal project in the company, because I have used a lot of strange things for myself, so I have invested a lot of energy, I hope to make this project succeed. From the beginning of the structural design, although three layers, it is accurate that it should be multi-storey, the structure of the e-commerce senior programming published in Wrox (originally wanted to use the architecture, later giving up, the word is too scary ). Simply put in the database and stored procedure, first put a Core layer, create the core data base class, the business base class, the base class, and then create the three layers in each module, these layers inherit the core layer Three base classes. In the current point of view, the advantage of this project is that all modules are very independent and the system is easy to expand. Now, the stage of creating a database store is now, because the stored procedure is to be completely used, so it is basically designed when all of these stored procedures are created, and some demand is not clear and the design is slow. The emergence of it, how to improve it, now feel more trouble, after all, because of the lack of experience, plus a bit too much to pursue perfect, so I don't know how to get started. Fortunately, I thought about yesterday, "I will make it simply", yes, that is, simplicity, simplification, and simplify! In fact, I don't have a little disappointment or no expert's person to guide, so whether it is from the grasp of the project itself, it is a big lack. From the start of work, I have never encountered a such environment, it is a regret, but it is also a challenge!
