The structured query language is the programming language that allows you to manage data in the relational database. SQL is the predominant language for crafting and overseeing databases utilized by various applications. A multitude of web and mobile apps rely on SQL for storing diverse data, ranging from customer profiles and shopping cart contents to search histories. Notable database systems that SQL can be employed to interact with encompass MySQL, Microsoft, Oracle, and more. Writing SQL queries, you can create, manage, update and manipulate databases. There are different types of SQL which are adopted widely by enterprises globally:
Data Definition Language (DDL)
The commands in this type will help you to define the schema or the structure of the database.
Data Manipulation Language (DML)
This type will help you to modify the database by inserting the data, modifying the data available and deleting the data. It allows you to carry out all the tasks that are required for you to modify the data.
Data Control Language (DCL)
The commands that are included in this type of SQL are grant and revoke which helps you to get the rights and permissions to access the data.
Transaction Control Language (TCL)
It has various commands that deal with transactions in the database.
Data Query Language (DQL)

Following are the topics on which many students will face difficulty in writing SQL queries:
Keys in SQL
The key is the single or multi-combination field available in the database table. This helps you to select the data with different characteristics like table name and field name. Keys help you to establish relationships with tables. Keys are what ensure that related data is in the same table.
Views in SQL
Views are called virtual tables that would display data in the other tables. The view will show you all or some rows in one or multiple tables.
Join will combine two or more tables in the database. This linking happens with the common values in each table. It helps you to fetch data from two or multiple tables.
It is a design technique that will reduce redundancy by segregating large tables into smaller ones and linking those tables with the help of relationships.
