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:
Relational Database Management System (RDBMS)
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.
It is secure
MySQL consists of a solid data security layer that protects sensitive data from intruders. Also, passwords are encrypted in MySQL.
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.
Free to download
MySQL is free to use so that we can download it from MySQL official website without any cost.
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.
MySQL is considered one of the very fast database languages, backed by a large number of the benchmark test.
MySQL supports a large number of embedded applications, which makes MySQL very flexible.
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).
MySQL allows transactions to be rolled back, commit, and crash recovery.
Its efficiency is high because it has a very low memory leakage problem.
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.
MySQL uses Triggers, Stored procedures, and views that allow the developer to give higher productivity.
It can download, install, and execute on most of the available operating systems.
This feature improves the performance and provides fast management of the large database.
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.
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
Following are the few disadvantages 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.
