How to introduce Visual Studio data, in view of this problem, this article introduces the corresponding analysis and answer in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Therefore, we need to add a Visual Studio data to compare our expected value with the return value. In our Visual Studio data section, delete the Visual Studio data, then select Scalar Value in the drop-down list and click the add button.

The efficiency of OO programs is not necessarily slower than that of the data + process, because OO is more able to implement Once and Only Once, easier to analyze the bottleneck of the problem, and therefore better able to optimize efficiency. Efficiency optimization is not optimized at 100%, but at 20%.

-- to take a practical example, OR Mapping is generally more efficient than your handwritten program, because in the development of an ORM product, it only needs to be optimized in a few limited places and for a few limited areas that affect efficiency, while manual programming generally needs to be optimized in many places, and every time it is not done, it has to be handwritten, manually maintained, manually optimized. On the other hand, OR mapping absorbs the expert knowledge of the whole community and makes continuous reuse and progress.

To say the least, even if you are a very good database programmer and the code you write is more efficient than OBank R, you can't guarantee it everywhere, and you can't guarantee everyone. Software projects are teamwork.

The important role of OO is the extensibility, stability and adaptability of programs, as well as the use of user-oriented languages and concepts to analyze and solve problems. This is a more important efficiency and optimization than your 5% (if any) improvement in database storage.

In 2004, we were still talking about the pros and cons of data modeling and object modeling, which I think is very ridiculous for most programs. This should be the issue discussed in 1994. But I'm not saying that data modeling is useless. Data modeling can still solve the problem. At present, many people are still writing management systems in C and PB, and they can still do good programs. Whether the user's business can be well realized is final.

It's just that in 2004, I was reluctant to send letters to the post office. Instead, I was willing to use email to send mail. Integration tools such as OFBIZ are still very advantageous in small-scale systems.

My experience of Ofbiz is not very deep. Ofbiz transforms the problems that must be solved by Java programming into data modeling with xml files, which really reduces the development effort. Many of the problems that had to be solved programmatically are now just xml files (more xml files, less code).

What we do is MIS class database operation-intensive software development, so our framework is also data modeling as the core. As for the reusability of the business framework, my consideration is that the business framework is designed to solve more complex business problems, that is, for a wider range of reuse, in which the reusability of each part is not very important. there is no criticism that the parts are tightly coupled.

This is the answer to the question about how to introduce Visual Studio data. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
