GORM: An Object Relational Mapper for Go
This course provides an in-depth examination of GORM and how to use it to provide an interface between a Go application and a relational database.
What you'll learn
Go is a language based on simplicity and speed. However, the complexity of an application can rise substantially when it has to interact with a database. GORM is a library that provides object-relational mapping capabilities to eliminate much of this complexity. This course will introduce you to GORM and help you learn about how to integrate it into your next data-driven application.
