How do you record a data driven test?

We can create a data-driven testing using data from a flat file, data table or a database.
Using Flat File: we actually store the data to be used in a required format in the file. We access the file using the File manipulation commands, reads data from the file and assign the variables with data.
Data Table: It is an excel file. We can store test data in these files and manipulate them. We use the ‘ddt_*’ functions to manipulate data in the data table.
Database: we store test data in the database and access these data using ‘db_*’ functions
