MySQL is one of the most famous Relational Database to store handle your data. In this What is MySQL blog, you will be going through the following topics:What are Data Database?Database Management System Types of DBMSStructured Query Language(SQL)MySQL its featuresMySQL Data TypesWhat are Data Database?Suppose a company needs to store the names of hundreds of employees working in the company in such a way that all the employees can be individually identified. Then, the company collects the data of all those employees. Now, when I say data, I mean that the company collects distinct pieces of information about an object. So, that object could be a real-world entity such as people, or any object such as a mouse, laptop etc.Now, when you have such a large amount of data, you obviously need a place to store it, which is a Database.So, you can consider the database as a big container, wherein you can store all the da ta. But do you think you can use your data without a proper management of the database?Its an obvious No!So, lets know what exactly is Database Management System and its various types.Database Management System Types of DBMSADatabase Management System(DBMS) is a software application that interacts with the user, applications and the database itself to capture and analyze data.The data stored in the database can be modified, retrieved and deleted, and can be of any type like strings, numbers, images etc.Types of DBMSThere are mainly 4 types of DBMS, which are Hierarchical, Relational, Network, and Object-Oriented DBMS.Hierarchical DBMS: As the name suggests, this type of DBMS has a style of predecessor-successor type of relationship. So, it has a structure similar to that of a tree, whereinthe nodes represent records and the branches of the tree represent fields.Relational DBMS (RDBMS):This type of DBMS, uses a structure that allows the users to identify and access datain relationto another piece of data in the database.Network DBMS: This type of DBMS supports many to many relations wherein multiple member records can be linked.Object-oriented DBMS: This type of DBMS uses smallindividualsoftware called objects. Each object contains a piece of data, and the instructions for the actions to be done with the data.Now, that I have told you about DBMS, its time that we understandwhat is SQL?Subscribe to our youtube channel to get new updates..! Structured Query Language (SQL)SQL is the core of a relational database which is used for accessing and managing the database. By using SQL, you can add, update or delete rows of data, retrieve subsets of information,modify databases and perform many actions. The different subsets of SQL are as follows:DDL (Data Definition Language) It allows you to perform various operations on the database such as CREATE, ALTER and DELETE objects.DML (Data Manipulation Language) It allows you to access and manipulate data. It helps you to insert, update, delete and retrieve data from the database.DCL (Data Control Language) It allows you to control access to the database. Example Grant or Revoke access permissions.TCL(Transaction Control Language) It allows you to deal with the transaction of the database. Example Commit, Rollback, Savepoint, Set Transaction.Alright! So, now that you know SQL, its time I introduce to MySQL.What is MySQL its FeaturesMySQL is an open-source relational database management system that works on many platforms. It provides multi-user access to support many storage engines and is backed by Oracle. So,you can buy a commercial license version from Oracle to get premium support services.The features of MySQL are as follows:Fig 1: Features of MySQL What is MySQL?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 Amazons 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 edition.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 h umongous amount of data.Now, that you guys know what is MySQL, let me tell you various data types supported by MySQL. Interested to learn more about MySQL Learn Now MySQL Data TypesFig 2:MySQL Data Types What is MySQL?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 length of bits. There is also a variable-length bit string data type called BINARY LARGE OBJECT(BLOB), whichis 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: Y EAR, 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 mentionsa relative value that can be used to increment or decrement an absolute value of a date, time, or timestamp.
