When I just participated in the work, every colleague around him seems to be longer than I have, and I don't know most of the colleagues. Most of my colleagues have become a little brother, my little sister, I'm going back, I have to enter the year. Ok, talk less nonsense, talk about the experience of software development in the years, share it with you. The initial writing program is used in foxpro. Of course, I can't talk about any theoretical guidance. I later saw a book of books in the design of the relational database, and learned the concept of paradigm, as a milestone. China's university education is really failure. Many people's computer undergraduate graduates, even this is not understanding, the procedures written are simplified. I have seen a guy's design process. A table has more than 100 fields. It is really sweating, actually relying on this When the computer manager, the monthly salary is 16000! ! ! Later, in 1997, Delphi1.0 just came out soon, as if Java started at this time, there was a PB than these two, and the Internet was also slowly popular in China. Hardware Aspects are the historical age of P166, 97 years. I chose Delphi, the main reason is to like the style of Pascal. It is from the beginning of this era, and it is also the time when the client / server system is said. At that time, Java, Delphi, VB book mixed, finally understood inheritance, polymorphism. However, writing a program seems to be at all, and the most is still a process of process. When Delphi3.0, the three-layer model started to fly. MS has a COM, COM , Borland has Midas, Data Model, and even Sybase is known as PB support 3-layer model, now it is true that these foreigners can blow, especially IT. During this time in 2000, I saw a book of Li Wei, I think many people have read the book, which I think that the only valuable thing is the design of the disconnected data set. Pattern, the other is garbage. However, if I said, Li Wei came later, I have a book that analyzes VCL, and it is really a little value, it is too late. During this time, the biggest regret is that there is no book in this regard, nor is it concerned about the development of Java. Time is wasting in Li Wei, this time the middleware is also blown, even the gold butterfly This kind of garbage company also wanted to do, and did not understand what this is something, it is until a few years later, I understand. I have been in 2002, I really don't know how to do this 3-layer model and COM, I started reading UML, J2EE, as if I have a feeling of opening, but I always feel that it is still a line. Until one day, I saw the agile software development of Robert Martin in Shenzhen Book City. Because I saw a lot of design patterns, agile development, and extreme programming, I saw this book and looked up. 2 pages, I will conclude this is the book I need, I will buy it back and have a feeling of reading. Later, I started using C #, studied several sample programs, what PETSHOP, what duwamish, finally basically open. Finally, I will welcome all netizens to discuss. Now that we write procedures to pay attention to any objective design, but actually applied it difficult. It fundamentally has the following obstacles, objects between objects, objects between databases, objects between networks, hardware performance, Finally, the object is the obstacle between Data Aware controls designed by DataSet.
