Prerequisites for Learning Design Patterns in ASP.NET MVC [closed]

As a junior developer I have more than three months of experience in ASP.Net MVC. I be working on a project that uses DAO design pattern as the architecture. Since I wanted to create an application by implementing a design pattern, the lack of knowledge held me back. If I get to start learn design patterns, What are the prerequisites I need to know before-hand and what are some of good resources to use ?

NOTE: I want to create a demo application specifically in DAO design pattern as well
