Answer to Question 2

Not only SQL and relational database management systems provide value in different ways. Traditional RDBMS focus on avoidance of replication and reduced storage costs. Data is stored in tables and usually normalized to avoid update, delete, and modification problems. NoSQL discounts the avoidance of replication and storage costs and focuses on scalability, flexibility, agility, and versatility. NoSQL allows for large databases (i.e., Google) that would be impossible using traditional REBMS approaches.
