Today, the website is accessible from databases. Maybe the website you maintain is connected to the MySQL database. MySQL is a relational database management system (RDMS). We know that with the database, your website will jump from a dead static site and become "awesome" and energetic, personal data management, general daily database applications, and so on are all supported by the back-end database of the website. This is where MySQL is amazing! This article is about the MySQL database. I hope that you can learn more about the MySQL database from the summary. This will bring you into the MySQL world.
Cheap all-around Database
MySQL is a popular database system in the open source world and in the Web community. It has become a de facto standard for free database software. Why? In fact, the MySQL database is indeed a popular "underfloor" solution for the public. It attracts a large number of database users and database administrators, we will discuss this later.
Another reason for the huge success of Mysql is that it is especially convenient. In the open-source world, GPL is a standard license agreement for sharing open-source software. It stipulates that free software (we are talking about MySQL) can be used without payment, as long as any source code containing the GPL product is also used within the GPL-compliant conditions. Let's talk about it: you can download MySQL for free without having to use it.
Moreover, this does not mean that if your database uses MySQL, you must publish your software source code publicly. In fact, GPL must be executed only in the following two cases: first, MySQL code is a necessary component of your software in terms of functionality, the second is that you assign RDMS along with your own software. There are no restrictions for business or personal use. However, many companies that use MySQL usually adopt proprietary licensing protocols to prevent software source code leakage. The license agreement can be purchased on a per-database server basis. The starting price of an organization is about $200 (this price may be lower if the license agreement is distributed by volume ).

However, MySQL also has the biggest headache: it does not fully comply with ansi SQL standards. If you are particularly concerned about this issue and are worried about it, I suggest you read the article by Michael M. Gorman. This article describes the effectiveness of the ansi SQL standard, because, to be honest, no database system has always followed the SQL99 standard.
