A table makes up a collection of Built in Column Types that can be joined together in order to create relational result sets.
Each record in the table is called a row, and a table can have an infinite set of rows. Each row represents one piece of data, and each column can be thought of as representing a component of that piece of data.
So, for example, if we have a table for a customer information, then the columns may include information such as First Name, Last Name, Address, City, Country, Birth Date, and so on. As a result, tables have column headers, which specify the data types for that particular column.
