Databases are one of the most important and almost inseparable parts of any modern application architecture. They help us store data in a meaningful format so that they can later be queried by the application or end user to fetch results on demand.
In this chapter, we will see how Julia interacts with various databases, be it a Relational Database Management Systems (RDBMSs) or NoSQL database. We will cover the following topics in this chapter:
- How to connect with databases?
- Relational databases
- NoSQL databases
- Introduction to REST
