Software architectures and dependency injection
Lesson 1 - Introduction to software architectures
How software looked like before the object-oriented programming and what was the problem. Dependencies, SRP, High Cohesion, Low Coupling.
Lesson 2 - Monolithic and two-tier architecture
This tutorial explains the monolithic architecture and why to divide it using the Indirection and Controller design patterns. We'll program a 2-tier app.
Lesson 3 - Three-tier architecture and other multi-tier architectures
This tutorial introduces a view layer and adds views to our 2-tier app. Except of MVC, we'll also talk about MVVM and other architectures.
Lesson 4 - Wrong ways of passing dependencies - Static members
In this tutorial, we'll introduce bad practices of dependency management in 3-tier MVC apps. We'll keep creating new instances and use static members.
Lesson 5 - Wrong ways of passing dependencies - Singleton and SL
In this tutorial, we'll explain disadvantages of the Singleton and Service Locator design patterns for passing dependencies in three-tier MVC apps.
Lesson 6 - Passing dependencies with Dependency Injection
This tutorial explains what we did wrong till now, what Inversion of Control is and how the Dependency Injection pattern works in practice.
Lesson 7 - IoC container source code
In this tutorial, we'll complete our knowledge of multi-layered architectures and Dependency Injection with a simple IoC container implementation.
