nternational Foodies is an importer of exotic foods from all over the world. You landed a summer internship with the company and discovered that their product lists and the suppliers they buy from are stored in Excel workbooks. You offer to help by using your newly gained knowledge of Access to create a relational database for them. You will begin by importing the workbooks from Excel into a new Access database. Your manager mentions that she would also like a table that specifies food categories so that you can relate the products you sell to specific categories in the database. You will create a table from scratch to track categories, create relationships between the tables, and create some baseline queries.
Start Access. Open the downloaded Access file named Exp19_Access_Ch2_Cap_Foodies. Grader has automatically added your last name to the beginning of the filename. Save the file to the location where you are storing your files.
You will examine the data in the downloaded Excel worksheets to determine which fields will become the primary keys in each table and which fields will become the foreign keys so that you can join them in the database.
Open the Suppliers.xlsx Excel workbook, examine the data, and close the workbook. Open the Products.xlsx Excel workbook, examine the data, and close the workbook.
You will import two Excel workbooks that contain supplier and product information into the database.
Click the External Data tab, click New Data Source, point to From File in the Import & Link group, and then select Excel. Navigate to and select the Suppliers.xlsx workbook to be imported as a new table in the current database. Select First Row Contains Column Headings. Set the SupplierID field Indexed option to Yes (No Duplicates). Select SupplierID as the primary key when prompted and accept the table name Suppliers. Do not save the import steps.
Import the Products.xlsx workbook, set the ProductID Indexed option to Yes (No Duplicates), and select ProductID as the primary key. Accept the table name Products.
Change the Field Size of the QuantityPerUnit field to 25 in Design view of the Products table. Set the Field Size of ProductID and CategoryID to Long Integer. Save the changes and open the table in Datasheet view. Open the Suppliers table in Datasheet view to examine the data. Close the tables.
You will create a new table that will enable International Foodies to associate each product with a food category in the database.
Create a new table in Design view. Add the following fields in Design view and set the properties as specified:
Add the primary key field as CategoryID with the Number Data Type and Number assigned to a new category. (type the period) as the Description. Set the Caption property to Category ID.
Save the table as Categories.
Add CategoryName with the Short Text Data Type and Name of food category. (type the period) as the Description. Change the field size to 15. Set the Caption property to Category Name and the Required property to Yes.
Add CategoryDescription with the Long Text Data Type. Set the Caption property to Category Description. Switch to Datasheet view and save the table when prompted. You will enter Category data into the table in the next step.
You will add 8 records to the Categories table so that you have some sample data to test in the database.
Add the following records to the Categories table:
Category ID Category Name Category Description
1 BEVERAGES SOFT DRINKS, COFFEES, TEAS
2 CONDIMENTS SAUCES, RELISHES, SEASONINGS
3 CONFECTIONS DESSERTS, CANDIES, SWEET BREADS
4 DAIRY PRODUCTS CHEESES
5 GRAINS/CEREALS BREADS, PASTA, CEREAL
6 MEAT/POULTRY PREPARED MEATS
7 PRODUCE DRIED FRUIT, BEAN CURD
8 SEAFOOD SEAWEED AND FISH
Close the table.
You will create the relationships between the tables using the Relationships window.
Add all three tables to the Relationships window. Identify the primary key fields in the Categories table and the Suppliers table and join them with their foreign key counterparts in the related Products table. Select the Enforce Referential Integrity and Cascade Update Related Fields check boxes. Save and close the Relationships window.
You will use the Simple Query Wizard to create a query of all products that you import in the seafood category.
Add the ProductName, SupplierID, and CategoryID fields from Products (in that order). Save the query as Seafood Products.
Add a criterion in Design view, to include only products with 8 as the CategoryID.
Sort the query results in ascending order by ProductName. Run, save, and close the query.
You want to create a query that displays actual category names rather than the CategoryIDs. You are interested to know which meat and poultry products are imported. You will copy the Seafood Products query and modify it to delete a field, then add an additional table and field.
Copy the Seafood Products query and paste it using Seafood Or Meat/Poultry as the query name.
Open the Seafood Or Meat/Poultry query in Design view and delete the CategoryID column.
Add the Categories table to the top pane of the query design window. Add the CategoryName field to the last column of the design grid and set the criterion as “Seafood” Or “Meat/Poultry”. Run, save, and close the query.
You will create a query that identifies suppliers and their associated products. Because there is a relationship between the two tables, you can now pull data from each of them together as usable information.
Create a query in Design view that includes the Suppliers and Products tables. The query should list the company name, contact name, phone (in that order), then the product name and the product cost (in that order).
Sort the query by company name in ascending order, then by product cost in descending order. Run, close, and save the query as Company by Product List.
You determine that the data in the Company by Product List query could be summarized with a Total row. You will group the records by company name, and then count the number of products you buy from each of them.
Copy the Company by Product List query and paste it using Summary of Company by Product as the query name.
Open the Summary of Company by Product query in Design view and delete the ContactName, Phone, and ProductCost columns.
Click Totals in the Show/Hide group on the Query Tools Design tab. Click in the Total row of the ProductName field, click the arrow, and then select Count. The records will be grouped by the company’s name and the products for each company will be summarized.
Modify the field name of the ProductName column as Product Count: ProductName to make the field name more identifiable. Click Run in the Results group (20 records display in the Datasheet). The results display the product count for each company that supplies your organization. Save and close the query.
Close all database objects. Close the database and then exit Access. Submit the database as directed.
