SQL - Structured Query Language

SQL stands for Structured Query Language. It's a specific programming language. It manages and tweaks data in relational databases. This language presents an avenue. It's an avenue to interface with databases. It's used to carry out various operations. Operations such as storing, retrieving updating and wiping out data.

Let us envision a large box. In this box you store all your toys. Every toy has a particular name. For instance "Teddy Bear" "Race Car" or "Doll". You desire to arrange and engage with these toys in varying methods.

SQL resembles a mystical language. This language helps you with your toy box. However, it isn't used for toys. It is meant for organizing and engaging with information on a computer.

Following is an explanation of the fundamental tasks accomplished by SQL.

Getting Information: This task involves asking questions about the information. The questions are about what's inside the computer. Picture asking something like, "Tell me all names of my toys." SQL will produce a list with toy names.

Storing Information: SQL aids in putting new things into the computer. Think about the scenario where you acquire a new toy. Say, a robot toy. Use SQL to inform the computer. You'd say, "place 'Robot' in the toy box." The computer is then aware that you have the robot toy.

Changing Information: Sometimes you may wish to alter certain attributes of your toys. Picture an instance where you desire to color your teddy bear's shirt blue. SQL can be the solution. Inform SQL of your desired changes. It will facilitate these changes for you.

Taking Things Away: Occasionally one finds a toy they no longer desire. In this case you'd use SQL to instruct the computer to remove it. You can say "Remove 'Broken Toy'." The computer would thus eliminate the broken toy from your toy box.

Sorting and Grouping: There are times when you wish to arrange your toys in a specific order. This could be from the biggest to the smallest. Know that SQL has the capability to do this too.

SQL is akin to a magical language. It allows you to communicate with a computer. You can then tell the computer what you wish to do with your information. It’s very similar to how you'd interact with your toys in the toy box. Use SQL for organizing for finding and for changing. Use it on information present in your computer.
