around concurrency can cause the system to become essentially serial, limiting the ability to scale. Concurrent programming is not difficult, and there are some simple principles that can help when building a scalable system.If you do need to hold locks (such as local objects, database objects, etc.), try to hold them as short as possible.Try to reduce contention for shared resources and, as far as possible, compete to avoid critical processing paths

Label:In order to build a database with small redundancy and reasonable structure, we must follow certain rules when designing database. In a relational database, this rule is called a paradigm. A paradigm is a summary of a design requirement. In order to design a relational

Good habits of database design and use, good habits of Database Design Good habits need to be constantly cultivated and strengthened until they become a habit and then part of their thoughts. Before or after work, I want to read "three character classics" or "Di Zigui" for my little guy whenever I have time. He may not

, if we put the dough, shape, heat, and cooling in the same machine, then this machine can only make one kind of cake. However, if we divide these functions into different machines, some machines and faces, and some machine stereotypes, we can think of them. For example, a new cake can be made when the surface is first joined, heated, finalized, and cooled. You can even make a variety of things that are not cakes. Then we want to cope with the changes. We want to add the function of adding eggs

1. Avoid empty columns in the table; 2. duplicate values or columns should not exist in the table; III:The record in the table should have a unique identifier.When designing a database table, the database administrator should develop a good habit of using an idnumber.It uniquely identifies a row record, rather than distinguishing records by names, numbers, and other fields. Each table should have an ID colu

. The general framework of Instant Messaging deployment is also mentioned. Now, let's look at the technical difficulties. Some functional points that will not spread are not difficult. Just do it. Therefore, in the initial stage of software design, we should consider the difficulties that are easy to expand globally, just like cancer is in the blood. Don't fix it, and be careful when the whole body crashes
