Microsoft Access is a database management system included in the professional editions of the Microsoft Office suite. Access is a data manager that uses relational database concepts and can be managed by means of queries and reports.

  • What is a primary key?
A primary key is a field or set of fields with values that are unique throughout a table. Values of the key can be used to refer to entire records, because each record has a different value for the key.
  • What is a foreign key?
A foreign key is a field (or fields) in one table that references the primary key in another table.
