Discussion and student response

A relational database model allows database users to analyze data  thoroughly. To accomplish this, advanced commands such as "union" and  "intersect" may be used.

• Describe a business scenario where a "union" relational set operator may be used to merge two similar data sets.
• Analyze the analysis and data consistency advantages of using a  "union" operator rather than simply merging two data sets into one  result table, within the context of your business scenario.
• Be sure to respond to at least one of your classmates' posts.
