Technical requirements
Before we dive into our discussion, we must have the following in place:
- A web browser (to download the PostgreSQL installer)
- PostgreSQL version 15 or later (If you haven’t installed this yet on your machine, don’t worry—we will cover the step-by-step installation in this chapter)
The PostgreSQL queries are saved in the Packt GitHub repository for this book and can be accessed at https://github.com/PacktPublishing/Managing-Data-Integrity-for-Finance/tree/main/ch08.
Once these are ready, you may proceed with the next steps.
