7 Add a database to your application

This chapter covers

Setting up a local database
Choosing a SQL crate suitable for your needs
Adding a database connection to our web service
Mapping our structs to tables
Extending our code to run queries within the code
Running database migrations
Switching to a new database management system

In the previous chapter, we added the ability to log metrics about our applications. Next to the extraction of code into several modules, this makes for an already solid web service. We try to go through the steps as you would do at the start of writing a new web service.

Chapters 1 to 6 provided a solid foundation, which we will build out in the remaining chapters. We will move more and more toward a production-grade ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
