ACCOUNTING INFORMATION SYSTEMS Access and Data Analytics Test General Instructions. This exam has four parts. Part 1 is in class. Parts 2, 3, and 4 are take-home. Submit all parts to the designated dropbox folder. I expect your individual effort on all parts. Parts 2 to 4 are described in a separate document. Part 1 – Access (50 points). To get full credit, you must set up appropriate relationships among the tables and enforce referential integrity for each link. Your queries must produce the correct values, the fields must by labeled and formatted appropriately, and query designs must not include extraneous tables. In other words, you should follow the list of fundamental rules for Access posted on BeachBoard and included at the end of this document for reference. 1. Download the Fall_2019 database posted in the Access and Data Analytics Test Module under CONTENT on BeachBoard. 2. Ensure that primary keys are set and establish appropriate relationships among the tables: Stores, Vendors, Purchases, and Purchase_Items. Stores and Vendors should be linked to Purchases. Purchases should be linked to Purchase_Items. 3. Prepare the following queries, naming the queries qa, qb, qc, qd, corresponding to the identifying letters below: a. Use the purchase_items table to calculate the dollar amount of each item purchased in an extension query; name your new calculated field purchase_item_amount and format it appropriately. b. Use qa and the purchases table to sum the purchase item amounts for each purchase in an accumulation query; include all fields from the purchases table and the purchase_item_amount field from qa; name your summed field purchase amount and format it appropriately. c. Use qb and the vendors table to sum the purchase amounts from each vendor in another accumulation query; include vendor number, name, city, and state; name your summed field vendor purchases and format it appropriately. d. Use the qb query. Keeping all fields from qb, calculate the month of the purchase; name that field purchase month. BEFORE SUBMITTING, ask me to review your work. After I say that you are done, then submit your file to the BeachBoard DROPBOX. Be sure to close Access before you upload your results. 1 Some Fundamental Rules for Access 1. Look at your tables and think about what information those tables provide before you start linking tables and creating queries. 2. Make sure each table has a primary key designated. 3. Always establish relationships between tables first, before starting queries. 4. Always enforce referential integrity (or understand why you can’t). 5. No “expr1” field names. 6. Do not click on the big sigma to produce totals if the query doesn’t require totals (i.e., an extension query). 7. Avoid “SumOf…” field names in accumulation queries. 8. Include identifying information in addition to the primary key in accumulation queries that provide subtotals. 9. Always format new fields prope.
