What Is MySQL?

MySQL is an open-source relational database management system, which works on many platforms. It provides multi-user access to support many storage engines.

MySQL has various features that enable us to do many tasks such as comprehensive application development, providing availability and scalability.

Now, obviously, when you work at an industry level, you can’t do everything on the terminal right? You need some kind of dashboard which makes it easy for you to work with large databases and create models.

Well, the dashboard that can perform these actions is the MySQL Workbench.

MySQL Features

MySQL is a relational database management system (RDBMS) based on the SQL (Structured Query Language) queries. It is one of the most popular languages for accessing and managing the records in the table. MySQL is open-source and free software under the GNU license. Oracle Company supports it.

The following are the most important features of MySQL:

1.Relational Database Management System (RDBMS)

MySQL is a relational database management system. This database language is based on the SQL queries to access and manage the records of the table.

2.Easy to use

MySQL is easy to use. We have to get only the basic knowledge of SQL. We can build and interact with MySQL by using only a few simple SQL statements.

3.It is secure

MySQL consists of a solid data security layer that protects sensitive data from intruders. Also, passwords are encrypted in MySQL.

4.Client/ Server Architecture

MySQL follows the working of a client/server architecture. There is a database server (MySQL) and arbitrarily many clients (application programs), which communicate with the server; that is, they can query data, save changes, etc.

5.Free to download

MySQL is free to use so that we can download it from MySQL official website without any cost.

6.It is scalable

MySQL supports multi-threading that makes it easily scalable. It can handle almost any amount of data, up to as much as 50 million rows or more. The default file size limit is about 4 GB. However, we can increase this number to a theoretical limit of 8 TB of data.

7.Speed

MySQL is considered one of the very fast database languages, backed by a large number of the benchmark test.

8.High Flexibility

MySQL supports a large number of embedded applications, which makes MySQL very flexible.

9.Compatible on many operating systems

MySQL is compatible to run on many operating systems, like Novell NetWare, Windows* Linux*, many varieties of UNIX* (such as Sun* Solaris*, AIX, and DEC* UNIX), OS/2, FreeBSD*, and others. MySQL also provides a facility that the clients can run on the same computer as the server or on another computer (communication via a local network or the Internet).

10.Allows roll-back

MySQL allows transactions to be rolled back, commit, and crash recovery.

11.Memory efficiency

Its efficiency is high because it has a very low memory leakage problem.

12.High Performance

MySQL is faster, more reliable, and cheaper because of its unique storage engine architecture. It provides very high-performance results in comparison to other databases without losing an essential functionality of the software. It has fast loading utilities because of the different cache memory.

13.High Productivity

MySQL uses Triggers, Stored procedures, and views that allow the developer to give higher productivity.

14.Platform Independent

It can download, install, and execute on most of the available operating systems.

15.Partitioning

This feature improves the performance and provides fast management of the large database.

16.GUI Support

MySQL provides a unified visual database graphical user interface tool named “MySQL Workbench” to work with database architects, developers, and Database Administrators. MySQL Workbench provides SQL development, data modeling, data migration, and comprehensive administration tools for server configuration, user administration, backup, and many more. MySQL has a fully GUI supports from MySQL Server version 5.6 and higher.

17.Dual Password Support

MySQL version 8.0 provides support for dual passwords: one is the current password, and another is a secondary password, which allows us to transition to the new password.

Disadvantages/Drawback of MySQL

  • MySQL version less than 5.0 doesn’t support ROLE, COMMIT, and stored procedure.
  • MySQL does not support a very large database size as efficiently.
  • MySQL doesn’t handle transactions very efficiently, and it is prone to data corruption.
  • MySQL is accused that it doesn’t have a good developing and debugging tool compared to paid databases.
  • MySQL doesn’t support SQL check constraints.

MySQL Workbench Tutorial: MySQL Workbench and Its Functionalities

MySQL Workbench is a designing or a graphical tool that is used for working with MySQL servers and databases. This tool compatible with the older server 5.x versions and does not support the 4.x server versions.

The functionalities of MySQL Workbench are as follows:

  • SQL Development: This functionality provides the capability to execute SQL queries, create and manage connections to database servers using the built-in SQL Editor.
  • Data Modeling (Design): This functionality enables you to create models of your database schema graphically, perform reverse and forward engineer between a schema and a live database, and edit all aspects of your database using the comprehensive Table Editor.
  • Server Administration: This functionality enables you to administer MySQL server instances by administering users, performing backup and recovery, inspecting audit data, viewing database health, and monitoring the MySQL server performance.
  • Data Migration: This functionality allows you to migrate from Microsoft SQL Server, Microsoft Access, and other RDBMS tables, objects, and data to MySQL.
  • MySQL Enterprise Support: This functionality provides support for Enterprise products such as MySQL Enterprise Backup, MySQL Firewall, and MySQL Audit.

Now that you know about MySQL Workbench, let me next tell you the basic requirements and the steps to install MySQL Workbench.

MySQL Workbench (Download and Installation)

MySQL Workbench is a unified visual database designing or graphical user interface tool used for working with database architects, developers, and Database Administrators. It is developed and maintained by Oracle. It provides SQL development, data modeling, data migration, and comprehensive administration tools for server configuration, user administration, backup, and many more. We can use this Server Administration for creating new physical data models, E-R diagrams, and for SQL development (run queries, etc.). It is available for all major operating systems like Mac OS, Windows, and Linux. MySQL Workbench fully supports MySQL Server version v5.6 and higher.

MySQL Workbench covers five main functionalities, which are given below:

1.SQL Development: This functionality provides the capability that enables you to execute SQL queries, create and manage connections to the database Servers with the help of built-in SQL editor.

2.Data Modelling (Design): This functionality provides the capability that enables you to create models of the database Schema graphically, performs reverse and forward engineering between a Schema and a live database, and edit all aspects of the database using the comprehensive Table editor. The Table editor gives the facilities for editing tables, columns, indexes, views, triggers, partitioning, etc.

3.Server Administration: This functionality enables you to administer MySQL Server instances by administering users, inspecting audit data, viewing database health, performing backup and recovery, and monitoring the performance of MySQL Server.

4.Data Migration: This functionality allows you to migrate from Microsoft SQL Server, SQLite, Microsoft Access, PostgreSQL, Sybase ASE, SQL Anywhere, and other RDBMS tables, objects, and data to MySQL. It also supports migrating from the previous versions of MySQL to the latest releases.
