You are the assistant director for the Information Technology (IT) department at Healthy Living Motorcycles, Inc. In addition to overseeing hardware and software selection, system maintenance, and employee IT training, you create and maintain databases for the whole organization. The organization uses one central database rather than maintaining several individual ones to reduce data redundancy and errors. You will take the opportunity to create an efficient database to keep track of and manage information regarding the company’s employees, products, and shareholders.
You have an existing database that contains the products sold by the company. However, you need to create a table that will classify each product under a specific category. After the table is created, you import the category data into the new table.
Import the data in the 02a_ProductCategory.xlsx Excel file into a new table. Use the column headings from the Excel file, select the CategoryID field as the primary key, and then save the table as Product Category.
Hint: On the External Data tab, in Import & Link group, click New Data Source.

Description = This field is assigned a 2-letter code
Caption = Category ID

Set Indexed = Yes (No Duplicates)
Caption = Category Name
This is a required field
Set Indexed = Yes (No Duplicates)
Caption = Supplier ID
Description = All Supplier ID must begin with an “S”
Set Indexed = No
