Does the CVM have a database? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

Normally, the cloud virtual host is given away by the database, such as the Yunfeng host. Because the cloud virtual host is equivalent to the upgraded version of the virtual host, the virtual host originally has a database, and so does the cloud virtual host.

There are generally three commonly used databases: Access, SQL Server, and MySQL. With the upgrading of technology and server hardware, more and more websites begin to use MSSQL or MYSQL as the database of the website, and the previous ACCESS database websites have become less and less.

Access

Access is basically used in small websites, is a desktop database, only suitable for a small amount of data applications, in dealing with a small amount of data and stand-alone access to the database is very good, and efficient. But it can access no more than 4 clients at the same time. Access database has a certain limit, if the data reaches 100m or so, it is easy to cause the server iis to die, or consume the memory of the server and cause the website space to crash.

Mssql

Is a relatively large and perfect database, commonly used in windows, with NET ASP and other programs. Based on the server-side medium-sized database, it can be suitable for large-capacity data applications, and its functional management is much better than Access. It is powerful in the efficiency of dealing with massive data, the flexibility of background development, scalability and so on.

Mysql

Is a small open source free database, commonly used in windows, linux, and PHP programs to form a perfect pair. MySQL is the most popular open source SQL database management system. The core program of MySql is completely multithreaded programming. Threads are lightweight processes that can flexibly provide services to users without too many system resources.
