This article will explain in detail what the database and SQL are. Each has its own advantages, the content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

One: what is database and SQL

The database is the data collection of the system, the database supports the storage and operation of the data, and the database makes it easy to manage the data. for example, the online telephone directory must use the database to store people and phone numbers. and other contact information and other related data. [recommended: MySQL tutorial]

Structured query language (SQL) pronounced "SQL" or sometimes called "See-Quel" is actually a standard language for dealing with relational databases. SQL programming can be effectively used to insert, search, update, and delete database records, but not limited to optimizing and maintaining databases, MySQL databases, Oracle,Ms SQL servers, Sybase and other relational databases using SQL!

Second: the advantages of SQL Server's MySQL

MySQL supports multiple storage engines, each with its own specification, while other systems such as SQL servers only support a single storage engine. To understand this, let's take a look at the two storage engines supported by MySQL.

InnoDB:- has been the default storage engine provided with MySQL since version 5. 5, and InnoDB supports foreign keys for referential integrity and ACID standard transactions.

MyISAM:- is the default storage engine for MySQL before 5.5. MyISAM lacks support for transactions, which is simpler and higher performance than InnoDB.

Compared with other relational database systems, MySQL has high performance because of its simple design and support for multiple storage engines.

Compared with other relational databases, it is cost-effective and relatively cheap in terms of cost. In fact, the community version is free. There is a license fee for the commercial version, which is also cost-effective compared with the license fee for products such as Microsoft SQL Server.

Cross-platform-MySQL can run on many platforms, which means it can be deployed on most machines. Other systems, such as MS SQL Server, run only on the Windows platform.

In order to interact with MySQL, you need a server access tool that can communicate with the MySQL server, and MySQL supports multiple user connections.
