Designing tables in MS Access involves creating tables and defining the structure and data types for each column. The following steps outline the process:

1. Open MS Access and create a new database.
2. Click on the "Create" tab in the ribbon and select "Table Design."
3. In the "Table Design" view, create a table by entering the name of the first column in the first row.
4. Define the data type for each column by selecting the data type from the drop-down menu in the "Data Type" field.
5. Set the primary key for the table by clicking on the "Primary Key" button in the "Table Design" view and selecting the appropriate column.
6. Create additional columns and define their data types as needed.
7. Save the table by clicking on the "Save" button and entering a name for the table.

Defining relationships between tables involves creating relationships between columns in different tables that have a common value, such as a customer ID or order number. The following steps outline the process:

1. Open MS Access and open the database that contains the tables you want to relate.
2. Click on the "Database Tools" tab in the ribbon and select "Relationships."
3. In the "Relationships" view, click on the "Add Table" button and select the first table that you want to relate.
4. Repeat the previous step to add any additional tables that you want to relate.
5. In the "Relationships" view, click and drag the related column from one table to the related column in the other table.
6. In the "Edit Relationships" dialog box, select the type of relationship you want to create, such as a one-to-one or one-to-many relationship, and set any other relevant options.
7. Click on the "OK" button to create the relationship and close the "Edit Relationships" dialog box.
8. Repeat the previous steps for any additional relationships you want to create.
9. Save the relationships by clicking on the "Save" button in the "Relationships" view.
