"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.
Write a function named equals() that accepts two char arrays and return true if both arrays have the same characters in the same order. The function should return false otherwise. Write a simple main() function to test your function.
You have to create a code with two functions. The first function takes a string as an argument and returns a Boolean that indicates whether or not the number of parentheses is balanced (utilizing a stack).
