How do you relate tables?

You can relate the data present in multiple tables by using the concept of Foreign Keys. for example if we have an employee database that contains various details of an employee scattered in multiple tables, one column in each table can be used to logically group the data in all these tables. For example, the employee number column in each of these tables can be used to relate the data present in these tables.

What is the smallest unit of data in a database?

Relational databases consist of tables. Tables consist of columns and rows; think of a single page of a simple spreadsheet. The term "field" is often used to describe the intersection of a column and a row in a database table. (Some people use the term field interchangeably with the term column so this is not completely agreed upon so, alternately, you could refer to that piece of data as a "cell".) Each column in a database has a type. In some databases the smallest type is a "bit" which represents a 0 or 1 and can be interpreted as "false" or "true". So, if a column has a type of "bit" a field in that column is probably the smallest unit of data for that database.
