Most of these patterns were taken from Martin Fowler's book, Patterns of Enterprise Application Architecture. I highly recommend reading this book if you have anything to do with writing enterprise applications. Due to length limitations, I was unable to cover some other important patterns like Uni...
For a more detailed description, see Martin Fowler's Shared Database pattern in Hohpe and Woolf's Enterprise Integration Patterns [Hohpe04].Maintain Data CopiesInstead of sharing a single instance of a database between applications, you can make multiple copies of the database so that each ...
Inversion of Control (IoC) and IoC containers are patterns that have always seemed a bit daunting to me. Keep in mind that I’ve been coding for almost 30 years, so I imagine I’m not the only experienced developer who never made the mental transition to this pattern. Martin Fowler, a...
In his article on the subject, Martin Fowler created this useful image to describe the situation: Bounded contexts Inevitably, some concepts sit on the boundary and are shared between bounded contexts. Should you still have a single data model per bounded context, or are you then forced to hav...

A DTO's only purpose is to transfer state, and should have no behavior. See Martin Fowler'sexplanation of a DTOfor an example of the use of this pattern. Here's the difference:POCO describes an approach to programming(good old fashioned object oriented programming), whereDTO is a patternth...
for all enterprise operating systems, this method is often simple to implement. The disadvantage of this method is that two applications can lose synchronization with each other because each one is changing the file independently.
