n 2017​, McGrath ​& Sons, a small​ environmental-testing firm, performed 10 comma 800 radon tests for $ 280 each and 15 comma 600 lead tests for $ 180 each. Because newer homes are being built with​ lead-free pipes,​ lead-testing volume is expected to decrease by 13​% next year.​ However, awareness of​ radon-related health hazards is expected to result in a 4​% increase in​ radon-test volume each year in the near future. Jim McGrath feels that if he lowers his price for lead testing to $ 170 per​ test, he will have to face only a 7​% decline in​ lead-test sales in 2018.

1. Prepare a 2018 sales budget for Sons assuming that McGrath holds prices at 2017 levels.

2. Prepare a 2018 sales budget for McGrath assuming McGrath lowers the price of a lead test to $170. Should McGrath lower the price of a lead test in 2018 if the company's goal is to maximize sales revenue?

You are a data analyst with strong backgrounds in database design and management. In fact, you have learned from education, mentors, and experience the art of collecting data and transforming data into business intelligence and your experience in database design and management complements your abilities to analyze data. Your hypothetical employer, Park University, is in the process planning a new employee payroll database and has asked you for assistance. The database will be standalone but will need to have ability to communicate with other ODBC and SQL Server databases. The overall purpose of the database will be to input employee data for 100-150 employees. The database will need to input time and process data needed to document payroll and to create payroll checks. Park University at this point needs to understand and review options so that cost to develop and maintain this payroll database are kept at a minimum but without compromising security. Park University has requested information and has asked you to address the following questions: Would a full-scale Database Management System (DBMS) or Relational Database Management Systems (RDBMS) be required in this case? Discuss and defend your answer in scholarly detail!! Could Microsoft Access be a good option in this case? Discuss and defend your answer in scholarly detail!! Could even Microsoft Excel be used in this case maybe as a secondary database support application for further data analysis and statistical models? Discuss and defend your answer in scholarly detail!! What Systems Development Life Cycle methodology would you suggest in this case for the overall planning, design, implementation, and maintenance of this database? Discuss and defend your answer in scholarly detail!! What else might you need to cover to help Park University determine what type of database to consider for the new payroll database? Include any other important conclusions or content you see fit to support this assignment.
