Description

Data persistence is important to your application workflow. This course will teach you how to use Entity Framework Core 6 and 7 effectively to persist data from your DDD designed software.

What You'll Learn?

While DDD is focused on the domain, data persistence is still important to your application workflow and if you are using EF Core, it is important to understand how EF Core maps nicely designed domain models. In this course, EF Core 6 and Domain-Driven Design, you’ll learn to persist tactical designs of DDD with EF Core. First, you’ll explore why persistence is relevant to DDD. Next, you’ll discover how EF Core maps by default as well as how to help EF Core with mapping aggregates. Finally, you’ll learn how to organize data related logic using skills from DDD. When you’re finished with this course, you’ll have the skills and knowledge of EF Core needed to persist your lovely domain models, also addressing changes to EF Core 7 that will affect persistence of DDD models.
