How to Create Relationships Between Multiple Tables Using Data Model in Excel. Using Data Model, automate the data analysis and business modeling tasks in Microsoft Excel. See how it's done! Excel is a powerful tool for data. Aug 23, 2012 Excel is telling me that a relationship between the two tables might be needed, so I go ahead and create it. A couple of things to notice when working with relationships: Both columns chosen need to contain the same type of data (Zip Code in this case). They only work when one of the table’s columns contains unique values.

Data in one table often relates to data in another table. For example, you might have a Teachers table and a Class table, and the Class table might have a lookup relation to the Teachers table to show which teacher teaches the class. You can use a lookup column to show data from the Teachers table. This is commonly referred to as a lookup column.

Define a relationship

You can create several types of relationships from one table to another (or between a table and itself). Each table can have a relationship with more than one table, and each table can have more than one relationship to another table. Some common relationship types are:

Many-to-one - In this type of relationship, each row in table A can match more than one row in table B, but each row in table B can match only one row in table A. For example, a class has a single classroom. This is the most common type of relationship and is shown in the column list as a Lookup column
One-to-many - In this type of relationship, each row in table B can match more than one row in table A, but each row in table A can match only one row in table B. For example, a single teacher, teaches many classes.
Many-to-many - In this type of relationship, each row in table A can match more than one row in table B, and vice versa. For example, students attend many classes, and each class can have multiple students.

Additionally, you can set advanced cascading behaviors on many-to-one and one-to-many relationships whenever an action is taken on the parent table.

Excel Create Relationship Between Tables

Add a lookup column (Many-to-one relationship)

To add a lookup relation to a table, create a relation under the Relationships tab and specify the table with which you want to create a relationship.

On powerapps.com, expand the Data section, and then select Tables on the left navigation pane.
Select an existing table, or Create a new table
Select the Relationships tab.
Select Add relationship, and then select a relationship type, such as Many-to-one.
On the right pane, select a Related table for the Current table, and then select Done.
Select Save table.

Add a One-to-many relationship

To add a One-to-many relationship, create a relation under the Relationships tab and specify the table with which you want to create a relationship.

On powerapps.com, expand the Data section and select Tables in the left navigation pane.
Select an existing table, or Create a new table
Select the Relationships tab.
Select the down arrow to the right of Add relationship, and then select One-to-many.
Select a table. Notice the Look up columns will be shown on the Current table, they will default with the tables name (in this example Teacher) but you can change them if needed. Select Done to add the relationship to your table.
Note
In the case of a One-to-many relationships, the Look up column will be created on the related table, not the table you currently have selected. If you need the lookup on the current table, create a Many-to-one relationship.
Select Save table.

Add a Many-to-many relationship

To add a Many-to-many relationship, create a relation under the Relationships tab and specify the table with which you want to create a relationship.

On powerapps.com, expand the Data section and select Tables in the left navigation pane.
Select an existing table, or Create a new table
Select the Relationships tab.
Select Add relationship and then select Many-to-many. This opens a panel for you to choose the table you want to create a relationship to. Select the table from the Related table drop down.
After selecting a table, the names for the relationship and relationship table will appear. They will default with the names of the tables combined, but you can change them if needed.
Select Done to add the relationship to your table, and then click Save table.

Add advanced relationship behavior

While building a one-to-many or a many-to-one relationship, you can also set advanced behaviors.

These options are also referred to as cascading behaviors because they cascade down the hierarchy of related tables. For example, it may be desirable to delete the related tests and homework of a student if a student is removed from the system. This type of behavior is called a parental relationship.

On the other hand, you may decide that you don't want actions to cascade down the hierarchy. For example, in the teacher to class relationship you may decide that the child table (class) should not be deleted when a parent (teacher) is deleted. This is called a referential relationship.

As you model your business data by creating custom tables or when using existing Common Data Model tables, consider the behavior you require and the implications for the entire hierarchy of related tables and choose between one of the following standard behaviors:

Referential,
