Some Basics: Relational Databases
A relational database is used to store relational information across multiple tables and allows you to query information in more than one table at the same time. You can easily understand with the example: imagine you are working in the school office department and you need to track the number of Admissions information. This you can create Spreadsheets in Excel and store data in row and columns as per requirements such as student name, class, fee, registration, etc. As time passes your data will be increases. Repetition will take place and old entries will not disappear as per time. All these data will slow down your processing. You can ignore all these problems with the help of relational Database, create a separate sheet for different work and Try to store repeated customer details in one place.
