10 recommended articles about database design

This article mainly introduces the relevant information on the implementation of the PC-side WeChat code scanning registration and login functions developed by .NET WeChat. It is very good and has reference value. Friends in need can refer to the next one. Let me state in the preface that this article The focus is on implementing ideas. The code and database design are mainly to show the ideas. Do not copy it if there are projects that have strict requirements on code efficiency. I believe that anyone who has done WeChat development has done a lot of authorization, but generally speaking we do more authorization for mobile websites. To be precise, we do authorization under WeChat. One problem I encountered today is that the project supports WeChat and PC, and registration is open. It is required that after registering on the PC side or on the WeChat side, you can log in on the other side. In other words, whether it is PC or WeChat, "you are you" (relevant in some way). 2.

2. 5 Common Database Design Mistakes

# Introduction: Everyone makes mistakes, but as database administrators, we should try to avoid them to reduce costs for the company and ensure data quality. The following five database design mistakes must arouse our vigilance. 1. Choose appropriate data types to avoid excessive expansion of the database. Please pay attention to the selection of data types. For example, if you know that the value of a column ranges from 0 to 100,000, you don't need to use the BIGINT data type because the INT type will suffice.
