Chapter 1. The SQL and NoSQL Way

Databases play a vital role in our life. Almost every application relies on a database for its operation. A database could be a flat file with a few bytes of data or a more complex system holding petabytes of data. Designing a database model is essential for an application to work effectively. Since the dawn of database systems, SQL databases ruled this technology space. SQL databases work on a relational database model that uses a tabular structure in which each element has a defined relationship with the other. However, recently, new generations of NoSQL databases have been created to combat the rising demands of data, and they are seeing widespread adoption from both technology giants and startups alike. This new wave of NoSQL databases has created a new school of thought, which requires a radically different thought process when compared to SQL databases.

This chapter explores the major differences between SQL and NoSQL databases, and provides an insight into what it takes to think in the NoSQL way. Here, you will also learn how to make decisions based on reliability, performance, and complexity.
