51) Chapter 2 describes, the various ways in which data can be stored for differing purposes. Describe the two ways data can be organized and the purpose for each organizational structure.
Answer: Answers may vary slightly!
A relational database, is the type of database you are most likely to come across when extracting and using accounting and financial data. While it is often preferred to analyze data from a flat file (e.g., in an Excel spreadsheet, in which all the data are stored in one place), when it comes to storing data and maintaining data integrity, a relational database is preferred because of its ability to maintain “one version of the truth” across multiple data elements.

52) Taylor is a new staff accountant for a fortune 100 company. After hearing that she just successfully completed an Accounting Data Analytics course, her boss said, “Get me a listing of all our deadbeat customer, so I can cut off their credit.” After asking clarifying questions, Taylor was able to determine that root request was “Which customer, with a credit limit over $10,000, have more than $5,000 outstanding for more than 90 days at the prior quarter’s end?” Use the ETL Techniques briefly describe the process Taylor with have to complete to answer her boss’ question. (Assume that Taylor does not have direct access the data, data will export into an Excel file, and she will complete the analysis with an Excel Pivot Table.)
Answer:Answers will vary but should include some of these items.
- EXTRACTION: Taylor completed step 1 by asking her boss clarifying question to determine purpose and scope of the data request. To complete step 2 she should complete a template to request the data from the system administrator.
- TRANSFORMATION: For step 3, Taylor will need to validate the data for completeness and integrity. She can compare the total AR balance of the data extracted to the gross AR amount on the financial statement from the prior quarter’s end. For step 4, Taylor should clean the data by removing headings or subtotals, ensuring formatting is consistent, etc.
- LOADING: No additional loading is necessary as the analysis will be run in Excel.

53) Define and compare a primary key, a foreign key, and non-key attribute.
Answer:Answers will vary!
- The purpose of the primary key is to ensure that each row in the table is unique, so it is often referred to as a “unique identifier.”
- Each table must have a primary key. The primary key is typically made up of one column, but it can occasionally be made up of a combination of columns. It is rarely truly descriptive; instead, a collection of letters of simply sequential numbers are often used.
- The purpose of the foreign key is to create the relationship between two tables. The relationship is created by placing a foreign key in one of the two tables that are related.
- Whenever two tables are related, one of those tables must contain a foreign key to create the relationship. The foreign key is special type of attribute as it must be the primary key in a related table.
- The other columns in a table are descriptive attributes.
- Primary and foreign keys facilitate the structure of a relational database, and the descriptive attributes provide actual business information.

54) Assume that you will be up for a promotion next month and you’d like to analyze a recently acquired database to show off your data analytic skills. After identifying the goal of your data analysis, using the first step of the IMPACT cycle, what steps would you take if you have direct access to the database?
Answer:Answers may vary!
- Identify the tables that contain the information you need. You can do this by looking through the data dictionary or the relationship model.
- Identify which attributes, specifically, hold the information you need in each table.
- Identify how those tables are related to each other.

55) Assume that you have just completed the extraction process on a data set. As you begin validating the data for completeness and integrity, you notice an error. Describe the steps you might take to determine the source of an error.
Answer:Answers will vary! A potential answer might include:
If an error is found, depending on the size of the dataset, you may be able to easily find the missing or erroneous data by scanning it with your eyes. However, if the dataset is large, or if the error is difficult to find, it may be easiest to go back to the extraction and examine how the data was extracted, fix any errors in the SQL code, and re-run the extraction.
