A package for working with a database

This section will develop a Go package for working with a given database schema stored on a Postgres database, with the end goal of demonstrating how to develop, store, and use a package. When interacting with specific schemas and tables in your application, you usually create separate packages with all the database-related functions—this also applies to NoSQL databases.

Go offers a generic package (https://golang.org/pkg/database/sql/) for working with databases. However, each database requires a specific package that acts as the driver and allows Go to connect and work with this specific database.

The steps for creating the desired Go package are as follows:

• Downloading the necessary external Go packages for working with PostgreSQL.
• Creating package files.
• Developing the required functions.
• Using the Go package for developing utilities.
• Using CI/CD tools for automation (this is optional).
