Please someone help me 1-9. I have posted this question several times now and no one has even attempted to help me.

Module 3 Database Assignment Please answer the following using the invoice and the database tables that follow these pages (each question is worth 2 points except for #9, which is worth 4 points). 1. Based on your readings from the textbook, which attributes are the likely primary keys for each of the 4 tables shown? a. Inventory? b. Sales? c. Customer? d. Sales-Inventory? 2a. Are any of the primary keys that you identified above considered a \"composite\" primary key? 2b. If yes, which one(s)? 3. Based on the database tables you have been provided, which of the Snerd International invoice (shown on page 4 of this assignment) fields are calculated by the ERP program rather than stored in the database? 4. Identify each of the \"foreign\" keys that are included as attributes in the database tables shown. Foreign keys are \"copies\" of the primary key of another table that are included in the linking table. These key fields allow the database to share data among the various tables. Note that any given table can have zero, one or more than one foreign key included among its attributes. I have completed the first one (Inventory table) for you a. Inventory table: no foreign key b. Sales table: ? c. Customer table: ? d. Sales-Inventory table: ? 5a. Will the fulfillment of the invoice shown on page 4 of this assignment result in any stockouts of inventory based on the data in the tables shown? 5b. Briefly explain how you determined the answer to 5a. 6. Which of the database tables shown include standing data (from Module 1, Ch. 3 readings)? 7. The recording of an invoice represents business event processing. Identify the specific database values that recording the invoice would change, if any, in each of the tables listed - a. Inventory table b. Customer table c. Sales table d. Sales-Inventory table (continued on next page) 8. Find a recent receipt from a purchase you made at a chain store (not a \"Mom and Pop\" store) and provide the code used on the receipt to indicate at which store location you made your purchase. Type the code in its exact form and the store name. Using this code, pick the coding scheme that you believe was used to identify the store (see Technology Summary 5.2, pp. 155-156) and explain why you think this is the scheme that was used. 9. (4 pts) When looking specifically at the relationship between the Inventory and the Sales-Inventory table a. which of the tables has the primary key of this relationship (see page 164)? b. which has the foreign key of the relationship? c. Would you describe the relationship between these 2 tables (Inventory and Sales- Inventory in that order) as a 1:N, M:N, N:1 or 1:1?
