MySQL is an open-source relational database management system (RDBMS) that is used to store and manage structured data. It is developed by Oracle Corporation and is used by many web applications and websites as a backend database.
The features of MySQL are as follows:
Ease of Management – The software very easily gets downloaded and also uses an event scheduler to schedule the tasks automatically.
Robust Transactional Support – Holds the ACID (Atomicity, Consistency, Isolation, Durability) property, and also allows distributed multi-version support.
Comprehensive Application Development – MySQL has plugin libraries to embed the database into any application. It also supports stored procedures, triggers, functions, views and many more for application development. You can refer to the RDS Tutorial, to understand Amazon’s RDBMS.
High Performance – Provides fast load utilities with distinct memory caches and table index partitioning.
Low Total Cost Of Ownership – This reduces licensing costs and hardware expenditures.
Open Source & 24 * 7 Support – This RDBMS can be used on any platform and offers 24*7 support for open-source and enterprise editions.
Secure Data Protection – MySQL supports powerful mechanisms to ensure that only authorized users have access to the databases.
High Availability – MySQL can run high-speed master/slave replication configurations and it offers cluster servers.
Scalability & Flexibility – With MySQL you can run deeply embedded applications and create data warehouses holding a humongous amount of data.
MySQL Data Types
Numeric – This data type includes integers of various sizes, floating-point(real) of various precisions and formatted numbers.
Character-string – These data types either have a fixed, or a varying number of characters. This data type also has a variable-length string called CHARACTER LARGE OBJECT (CLOB) which is used to specify columns that have large text values.
Bit-string – These data types are either of a fixed length or varying lengths of bits. There is also a variable-length bit string data type called BINARY LARGE OBJECT(BLOB), which is available to specify columns that have large binary values, such as images.
Boolean – This data type has TRUE or FALSE values. Since SQL, has NULL values, a three-valued logic is used, which is UNKNOWN.
Date & Time – The DATE data type has: YEAR, MONTH, and DAY in the form YYYY-MM-DD. Similarly, the TIME data type has the components HOUR, MINUTE, and SECOND in the form HH:MM: SS. These formats can change based on the requirement.
Timestamp & Interval – The TIMESTAMP data type includes a minimum of six positions, for decimal fractions of seconds and an optional WITH TIME ZONE qualifier in addition to the DATE and TIME fields. The INTERVAL data type mentions a relative value that can be used to increment or decrement an absolute value of a date, time, or timestamp.
MySQL is a reliable database management system that offers a range of features and benefits to users. Its performance, scalability, and security make it a popular choice for web applications and websites, and its community support ensures that it remains a relevant and valuable tool for developers and businesses alike.
