MySQL - Workbench

Table of content

The MySQL workbench is a graphical tool for working with MySQL servers and databases. It is developed and maintained by Oracle. This application includes various features such as data modelling, data migration, SQL development, server administration, database backup, database recovery and many more. MySQL Workbench supports the MySQL versions 5.7 and above.

The versions of MySQL prior to version 5.7 are deprecated and they are incompatible with MySQL workbench. Therefore, we need to ensure that they should be upgraded before we make a connection.

MySQL Workbench is a recommended application for database developers and administrators. We can download this application on Windows, macOS, and Linux operating systems.

Functionalities of MySQL Workbench

Following are the five main functionalities of MySQL workbench −

SQL Development − This functionality allows to create and manage connections to database servers. SQL queries can be executed on the database connections using the built-in SQL editor in MySQL workbench.
Data Modelling (Design) − This functionality allows to create models of our database schema graphically, reverse and forward engineer between a schema and a live database, and edits all aspects of the database using the comprehensive table. The table editor provides facilities to edit Tables, Columns, Indexes, Triggers, Partitioning, Options, Inserts, Privileges, Routines and Views.
Server Administration − It allows us to administer the MySQL sever instances by administering users, viewing database health, performing backup and recovery, inspecting audit data, and monitoring the MySQL server performance.
Data Migration − It allows us to migrate from the Microsoft SQL server, Microsoft Access, Sybase ASE, SQLite, SQL Anywhere PostreSQL, and other RDBMS tables, objects and data to MySQL. Migration also allows us to migrate from prior versions of MySQL to the latest releases.
MySQL Enterprise support − This functionality provides the support for Enterprise products such as MySQL Enterprise backup, MySQL Firewall and MySQL Audit.

It allows us to configure the server paramerters. It shows various details about the sever and status variable, number of threads, buffer allocation size, fine-tuning for optimal performance, etc.

Database Backup and Restorations

This tools is used for importing and exporting the MySQL dump files. These dump files contains the SQL script for table creation, view creation, stored procedure creation etc.

Server Logs

This tool shows log information for the MySQL server by each connection tab. For every tab connection, it includes an additional tab for the general error logs.

Performance Dashboard

This tab provides real-time statistical view and analysis of server performance such as CPU usage, memory usage, query execution time, etc.
