this assignment is to write a comparison between a NoSQL database and a relational database.

The use of document-based schemas means fewer relational joins and makes it easier to distribute data across multiple servers. The schema of a NoSQL document can be very flexible, but there are still cases where it may be useful to break out tables and provide some data isolation.

For this assignment, you are a software engineer developing a new payroll system for a startup company. Your startup has very aggressive goals, and within the first year you intend to support:

• Ten thousand customers
• Over one million employees
• Some companies will pay their workers weekly, others will pay bi-weekly, and others twice monthly
• Employees are expected to update their personal data whenever it changes

Your task is to think through the risks of running reports on a NoSQL database managing this payroll system. What could go wrong? If a problem occurs, what might be the impact? Will your reports be useful?
