Question: "Relational Set Operators" Please respond to the following:

- 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. Within the context of your business scenario, analyze the analysis and data consistency advantages of using a UNION operator rather than simply merging two data sets into one result table.

- Suppose you are tasked with finding common data elements amongst various data sets. Specify how an INTERSECT operator may assist you in accomplishing this task. Construct a query that can perform the same function as the INTERSECT operator without using the "INTERSECT" syntax within the query. Note: The Strayer Oracle Server may be used to test and compile the SQL Queries developed.
