In this post you will learn about SQL and why it is so important. As you all know SQL stands for Structured Query Language. It is a standardized programming language, deals with relational database and performs various operations with data such as update, delete, query, insert. All the RDBMS(Relational Database Management Systems) such as Oracle, MySQL use SQL as their standard database language.
Further, the SQL language is divided into clauses, expressions, queries, statements etc. SQL is a declarative, not an imperative programming language. It allows users to define and describe the data, create and drop tables. SQL has many more different functions.
SQL is important because of the following main reasons -
a. SQL helps you to find the needed information or data easily.
b. SQL is a query language, not a programming language. You can easily write commands almost same as you write English.
c. It quickly stores and gets data from the database quickly. SQL is used for the query, insert, collect and manages data from the database.
d. Almost every database system will need SQL for further processing.
4 Reasons to learn SQL if you are still not planning to learn it
a. It doesn't require coding - SQL easily manages the database system without any requirement of adding significant code. It does so by using standard SQL.
b. Portability - I think this is the main benefit of SQL. You can run SQL on PCs, laptop, servers, tablets, even on the smartphone. Also, the database can easily be moved from one device to other.
c. Easy to learn - As I told you, it is the easiest language contains English statements. You can easily learn to write queries and manipulate data.
d. SQL Standard - DQL databases are used by established standards. The first standard for this by ANSI (American National Standards Institute) in 1986 and ISO (International Standards Organization) in 1987.
