How to clean code
Sometimes writing code is like organizing and drawing architectural drawings. Without a clear idea and architecture, it is necessary to create a messy community
the so-called transaction isolation level. In fact, the four levels are defined to solve the problems caused by high concurrency of data. What are the problems?
First, let's look at "Dirty reading". When I see the word "dirty", I think of disgusting and dirty. How can the data be dirty? This is what we often call "junk data. For example, two transactions are executed concurrently (that is, competition ). Take a look at the following table and you will understand what I'm talking about:
