This document discusses various aspects of building a database in Microsoft Access, including: 1. Creating and defining fields in a table in Design view by specifying the field name, data type, description, and properties. 2. Specifying the primary key for a table by selecting the appropriate field in Design view. 3. Importing data from an Excel worksheet into an Access database table using the import wizard. 4. Defining relationships between tables to maintain referential integrity when updating data, including one-to-many relationships.

10. Defining Table Relationships
• A one-to-many relationship exists between two
tables when one record in the first table matches
one or many records in the second table.
– The Primary table is the “one” in a one-to-many
relationship
– The Related table is the “many” table

enforces to maintain consistency between
related tables when you update data in a
database
• The Relationships window illustrates the
relationships among a database’s tables
• Click the Database Tools tab on the Ribbon
• In the Show/Hide group on the Database Tools
