What is the benefit of learning SQL?
PURPOSE OF SQL DATABASE LEARNING FOR IT FIELD:
The main reason to learn SQL is, as so many of the others have pointed out, to access the data inside of databases. It’s the language used for most relational storage systems and derivations of it are available for some unstructured or semi-structured systems as well.
                     
A secondary, but extremely important, reason to work on learning SQL properly is because it’s not a programming language. It’s a query language. You need to learn it as such and learn how it differs, in some cases radically, from procedural and control languages. The one thing that gets people into trouble the most when learning and applying SQL is to treat it as the same as those other types of languages. SQL is not.
SQL is different and requires a different approach. For example, functions and views look like mechanisms of code reuse common in other languages. However, in SQL, they’re a trap that leads to poor performance and confusion.
Learning the different ways to program SQL will aid you in accessing data. Learning the ways that programming SQL is different from other languages will make a huge difference in your application of that data access.
- SQL is easier to learn than other programming languages, such as Java and C++.
- It helps you handle vast volumes of structured data.
- You can query a million rows of data using simple SQL commands.
- SQL lets you standardize and normalize your data.
- SQL is used to create and manage servers.
- You can manipulate your data and perform calculations.
- SQL lets you combine data from multiple sources and perform analysis on it.
Advantages of SQL
There are the following advantages of SQL:
High speed
Using the SQL queries, the user can quickly and efficiently retrieve a large amount of records from a database.
No coding needed
In the standard SQL, it is very easy to manage the database system. It doesn’t require a substantial amount of code to manage the database system.
Well defined standards
Long established are used by the SQL databases that are being used by ISO and ANSI.
Portability
SQL can be used in laptop, PCs, server and even some mobile phones.
Interactive language
SQL is a domain language used to communicate with the database. It is also used to receive answers to the complex questions in seconds.
Multiple data view
Using the SQL language, the users can make different views of the database structure.
