How to apply MySQL in the database management system, I believe that many inexperienced people do not know what to do. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

MySQL is a relational database management system developed by MySQL AB Company of Sweden and currently belongs to Oracle Company. MySQL is an associated database management system that stores data in different tables instead of all data in a large warehouse, which increases speed and flexibility. MySQL's SQL language is the most commonly used standardized language for accessing databases. MySQL software adopts the double authorization policy (this entry "authorization policy"), which is divided into community version and commercial version. Because of its small size, high speed and low total cost of ownership, especially open source, the development of small and medium-sized websites generally choose MySQL as the website database. Because of the excellent performance of its community version, it can form a good development environment with PHP and Apache.

At the same time, enterprises also take the ability of MySQL application as one of the screening criteria during the interview, so more and more programmers and people who are going to be programmers are beginning to learn this technology seriously.

To learn programming, you may hesitate to choose C++ or Java; to get started with data science, and you may struggle with choosing Python or R, but in any case, MySQL is an indispensable skill for IT practitioners!

Let's look at the role of MySql database management system through practical operation.

In the data connection page, there are search, refresh, new connection, data connection database, new connection name data type, connection string and other information

Procedure:

① refreshes the current page

② enters the connection name or connection type on the current page to search

The data modeling page opens the new table name, and on this page, you must fill in the table name, table description and table primary key (select the application primary key name in the drop-down box). In the field settings, you can add, delete, move up and down the field. it's easy to use.

Procedure:

The green "plus" sign in the ① field setting indicates the addition of the current line

The red minus sign in the ② field setting indicates that the current line is deleted

When you select a piece of data on the data modeling page, you can edit, delete, open data and view subdirectories.

Procedure:

If the current data selected by ① is applied, it cannot be deleted successfully.

② Select Table name Click the action triangle to display the subdirectory information under this directory

When ③ selects a data operation to open the data button, it goes to the current selection table data page.

Select the search criteria (F_ID, F_Parentld, F_FulName, etc.) in the data page of the current table and enter the keywords under the conditions to search. However, the current search data jumps to the page.

Procedure:

① if you clear the current input keywords, click to search, and the data will return to all the data pages of the current table.

When ② operates the current table data close button, the current table data page closes itself and jumps to the data modeling page.

Data synchronization page, operation data synchronization warm reminder: data synchronization is synchronized from A database to B database, you must ensure that the database table structure is consistent, otherwise synchronization will fail.

In the data connection, data modeling and data synchronization of JNPF rapid development platform, there are MySQL, SQL Server and Oracle databases at the same time, which can meet the data management needs of enterprises in many aspects.
