I recently talked with some friends about some things about the factory model. I think it is necessary to write an article to clarify the application methods of the abstract factory. In the abstract factory chapter, GoF does not spend much space on how to apply abstract factories. Fortunately, ADO. NET provides us with an example of a very standard Abstract Factory, and it is also a very practical interface

based index for that purpose.3) Inversion of keyword indexYou can also see these inverted keyword indices, and they are also used occasionally. Suppose there is a list of "restaurant a", "Restaurant B", "Restaurant C" and other similar names. This may not be a good example, but the key point is that there are many unique values, but the previous part of the keyword does not change much. Because Oracle simplifies the reverse string before assigning th

Preface: I haven't written any tutorials for a long time. The version upgrade is very fast. Because all versions are backward compatible, the original tutorials also apply, If you have time, please update it manually.

Therefore, everyone should leave their posts of different versions empty. Today, we have carefully written an example
