What Makes Up a Relational Database?

A relational database is a type of database that organizes data based on unique attributes. For example, a relational database may represent a data entry by employee ID, name, age, and date of birth. These unique characteristics are how relational databases organize the database structure such that data entries share a common relationship.

A relational database is made up of 3 basic elements: fields (columns), records (rows), and table. A record is a row of entries that reads from left to right and will be populated with data for employee ID, name, age, and date of birth.

A field is a column that stores a relational data entry. An example of a field could be employee ID. As you can imagine, the ID field column will be populated solely with ID values reading top to bottom.

Lastly, the table itself encompasses the entire relational database. So when you hear table, just think of the entire database of entries.
