Chapter 6: Interacting with Remote Data Sources

In the last chapter, we talked about dealing with common data formats and showed how we can read and write data in those formats. But in that chapter, we were simply dealing with data that was accessible through a filesystem.

While the filesystem may actually have files that exist on remote devices through services such as the Network File System (NFS) or the Server Message Block (SMB), other remote data sources exist.

In this chapter, we will look at some common ways to send and receive data in remote data sources. This will focus on accessing data on remote systems using the Structured Query Language (SQL), REpresentational State Transfer (REST), and Google Remote Procedure Call (gRPC). You will learn how to access common SQL data stores, with a focus on PostgreSQL. We will also explore how Remote Procedure Call (RPC) services are created and queried using REST- and gRPC-style RPC methodologies.
