SQL is a programming language for querying and manipulating data
It performs almost the same tasks as Excel, but it is superior to it in its ability to deal with large data, and thus shortens a great deal of data processing time compared to Excel, in addition to its ability to store data in small files.
However, the only aspect in which Excel excels over SQL is the ease of learning and handling of the main tasks.
The main function of SQL tool is to edit big data
For example, you have a very large number of posts on Instagram and you want to make edits or sort those posts with easy procedures and simple instructions.
It has an effective role in joining data sets together. You can rely on SQL to combine several spreadsheet files containing a number of fields in one file with the utmost smoothness and flexibility, avoiding complications, difficulties and wasting time that you face to perform this task in Excel.
