We require a medium that makes this data accessible, usable, and changeable.
What is SQL?
The Structured Query Language (SQL) is a query language for stream processing and database management that was developed in the 1970s. It enables the usage of the same database on several computers at the same time, which is highly useful while working in an office. From development to maintenance, SQL has a wide range of uses. It also offers sublanguages like DDL, DQL, DCL, and others that may be thought of as specialized statements for certain jobs.
What is SQL used for?
So, now that you know what SQL is, you might be asking what SQL is used for. It is, as previously said, a programming language that is used to connect with relational databases. But let's look into it a bit further. Some of SQL's applications are given below.
As a Data Definition Language (DDL)
One of the most common uses of SQL is as a Data Definition Language (DDL) to construct and alter data structures. The DDL commands are used to add, delete, and edit tables in a database. Some of the most regularly used DDLs include Create, Drop, and Alter. Furthermore, utilizing DDL, anybody may curate and arrange a database on their own, as well as use and discard it.
As a Data Manipulation Language (DML)
DML refers to the SQL commands that are used to perform database updates. These are used to update or remove data, even one cell or entry at a time. DML examples include "Insert," "Update," and "Delete." DML refers to SQL's ability to maintain an existing database by adding new data chunks and modifying, extracting, and saving them.
As a Client-Server Programming Language
SQL may be used as part of a three-tier architecture that contains, among other things, a client, an application, and a database. SQL is used as a Client-Server language to provide a link between the front-end and back-end, therefore simplifying the architecture. The Internet infrastructure is given a specified framework in this approach.
