They also vary in format or structure. We usually use the term big data for such types of data. Such large amounts of data can't be handled by a traditional relational database management system. That is why a new way needs to be discovered to solve this. This is how NoSQL came into existence. This chapter will introduce you to NoSQL and its fundamentals.
