Expert Solution & Answer
Chapter 8, Problem 8.15RQ
Explanation of Solution
Fact Table:
Fact table is the focal table of the dimension table that can store measure of the business activities.
- The qualities of the data present are called as measures.
- It holds the qualitative or factual data of the entity that are being represented in the fact table.
- Fact tables are normalized and are present at the center of the star schema.
- They do contain foreign key in joining the dimension tables...

Finally inputting an answer and the computer generates a new guess within the proper range. Oh and to make sure the program doesnt guess outside of the ranges produced by the inputs of “too high” and “too low”.
