Databases are essential for managing data effectively in web applications by providing a structured way to store, retrieve, and manipulate information. This chapter introduces the concept of databases, focusing on the differences between relational and non-relational databases, particularly MongoDB. It further explains how to set up MongoDB, define schemas, perform CRUD operations, and integrate these operations with an Express server for dynamic data management.
