The fact that you had so much data in it probably caused your spreadsheet to crash. Relational databases are designed to hold a large amount of data, often millions of rows. SQL allows you to carry out operations on this vast amount of data without fear of crashing..” Despite the fact that Microsoft Excel is a fantastic tool, it was not designed to conduct functions on millions of lines simultaneously. SQL is the program that allows you to do these massive jobs in relational databases.
