Talking about making software development is a casual thing. When you go to the university, I read economic management, just popular computer, Apple, 286, 386, or simple, the school set up a computer association, I am fascinated, there is no class to run, I don't understand the information, and the operation of the computer is also familiar with students more than many students who learn computer. However, most of the computer did not even have a hard disk, and the speed can be imagined. At that time, it was only familiar with the operation and did not learn the basics.
After graduating, I participated in the work. The first thing to take the year-end award was to buy a 386, 4M memory, 40M hard drive, color TV computer, and played in order to play a play. Playing for half a year, the game is too familiar, and I don't think it means. So learning FoxPro, there is a DOS version, Windows version, I chose the Windows version, after a effort, some small procedures can also be written. There is a chance to have a company to sell management software, specializing in statistical sales invoices, customer management, tracking conditions. At that time, I immediately agreed, but I truly did it very difficult. Later, I first concluded that I would like to understand the needs of customers, and then do data structures, business rules according to customer needs, and it is very easy to use, and finally Yes, it is encoded. At that time, such as the Arabic number turned RMB uppercase, password encryption decoding had a lot of time, and eventually developed successfully. Delivery use is also very good. After a period of improvement, it is used to use the branches. At that time, it was also deliberately added the registration function. It was really shocking ... Subsequently developed some special customer files. , Sales plan management, after-sales service, etc. Application software, usage platform, upgrade from Win32 to Win98. FoxPro has also appeared 3.0 version, but I think it is not very easy, 2.6 is very good, I also use it to develop a point of song, put the songs to the songs, play at any time. Later, I turned with delphi3.0, using it to develop a dormitory management system, including complicated hydropower, rent-sharing management, and it is also very easy to use. Solved the cost calculation of thousands of people.
Later, a computer company was joined, officially knewing software development this line. The first task is to design a canteen management software for the company. It is a cartoon image engineering, using computer à la carte form, dynamic management, card value, consumption function, 30 sale meals workstation parallel, use 486DX100 as a workstation, at the time Only I am familiar with Delphi, only one person has done the development tool to use Delphi5.0, the data library selection SQL Server 7.0, the workstation selection Win95, the server installed NT 4.0 uses the storage process and the view, spend a month to complete The program does not feel slow in 486DX100, Win95. After a week of testing, there is no big problem, the system is on, and I didn't sleep on the night, I don't know how the second day, the result has a small problem. Because the card at the time is to distinguish management and general staff, a parameter is wrong, but fortunately, the custom management method is used, and the parameters solve the problem, but also surprised a sweat. It has been working in a few years, noon, late, and everything is working in the night. Later, according to the opinions of everyone, I also hung up supermarket, medical management, human resources, access control, attendance function, truly a card.
It is also aware that the shortage of knowledge, the basic knowledge is weak, and the data structure and algorithm must also be worried. But software technology has also developed rapidly, .net appears, I think C # is a relatively promising, so use C # to develop the first Web version of the enterprise information management system, including human resources, sales management, warehouse management and combine some Web version of the personal office function. The application is good, and the function needs to be strengthened. Software has been in so many years, I feel that the development is too fast, there are too many things to learn, and it is tired, and I have a sense of success, but the taste is only only I feel. Especially like I have more effort to spend more energy to engage in difficulties. The road is still very long, and there is no very good direction. I always feel the technical leap, I can adapt, the road, I can only go to open up, in front or a bright sunshine ...
