Establish relationships between tables in Access 2016

In this article, TipsMake.com will work with you to learn the necessity of creating relationships between related tables. The relationship between tables is the data link between tables. By defining these relationships, you can drag records from related tables based on the fields of each table.

One of the good database design goals is to eliminate data redundancy.

  1. To achieve that goal, you need to divide your data into multiple tables on multiple topics so that each entity is interpreted only once.
  2. To do this, all related fields will be placed in a table.
  3. To perform this step correctly, you must first understand the relationship between your tables and then specify these relationships in your Access database.

Why should relations be established between tables?

MS Access uses relationships to join tables that help you use them in a database object. You should create table relationships before you create other database objects such as forms, queries, macros, reports, and reasons like this:

  1. To work with records from two or more tables, you often have to create a query with the participation of multiple tables.
  2. The query works by matching the values ​​in the first primary key field of the table with the foreign key in the second table.
  3. When designing forms or reports, MS Access uses the information collected from defined table relationships to provide appropriate choices.
  4. When designing databases, you divide your data into multiple tables by multiple topics, each with a primary key and then add foreign keys to the relevant tables. Main key pairs - foreign key is the basis for table relationships and query multiple tables.

Now let's add another table of personnel information to your database and name it tblHRData with Table Design as shown in the following screenshot.
