Simply so, how do you create a relationship in access?
You define a relationship by adding the tables that you want to relate to the Relationships window, and then dragging the key field from one table and dropping it on the key field in the other table.
Beside above, what is primary key access? 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. Access automatically manages primary keys for new tables in Access web apps and web databases.
Simply so, which key defines relationship between two tables?
The term referential integrity is used to describe a specific relationship between tables. Each table in a database must have a primary key, the set of columns that define what constitutes a unique row of data.
Can two tables share the same primary key?
Yes, they can. But whether that's a good idea depends on how the data is used. Generally if two tables have the same primary key, it's because the data within the tables refer to the same object.
