In this chapter, we covered a series of commonly used architecture patterns and how we can practice DDD when working with them. We also looked at common pitfalls and gotchas that we may need to be cognizant of when using these architectures. We also looked at popular programming paradigms and their influence on the tactical elements of DDD.
Additionally, you should have an appreciation of the various architecture styles that you need to employ when coming up with a solution. In addition, you should have an understanding of how DDD can play a role, no matter which style of architecture you choose to adopt.
In the next section, we will look to apply all we have learned in this and previous chapters to a real-world business use case. We will apply both the strategic and tactical patterns of DDD to break a complex domain into subdomains and bounded contexts and iteratively build a solution, using technologies that are based on the Java programming language.
