To understand how the CodeBot enables large-scale parallel development we need to go back to Brooks’ Law, the widely believed postulate that you can’t accelerate a software project by throwing more developers at it.
DOMAIN DRIVEN DESIGN TUTORIAL GENERATOR
Specifically, how our domain driven database and API generator (aka Parallel Agile CodeBot) enables the Parallel Agile Process, which allows large teams of developers to collaborate more efficiently and breaks the “two pizza rule” on team size.

One of our biggest challenges at Parallel Agile is explaining how two apparently unrelated aspects of our business are actually very closely related. You don’t need to call the API directly because CodeBot generates client-side code including usage samplesĬodeBot is a complex product that does an incredible amount of work to simplify your life as a developer.
DOMAIN DRIVEN DESIGN TUTORIAL UPDATE
Use the API to Create Teams, Read Teams, Update Teams…Īnd a client-side layer that makes accessing the API nice and straightforward. To a Mongo DB collection with a NodeJS REST API (documented in Swagger), In this video we’ll follow the evolution of the TEAM object from a noun on a short problem domain description,Ī Team has an Owner and a Roster and a Schedule In our example, your app can show video of the players scoring touchdowns in near real-time This video will show you how in less than 3 minutes…which is about how long it takes for you to try it yourself. How easy is it to generate a working database and API from an EA domain model? Really, really easy. part of functionality MAY BE required in a WPF app - so we can use Service Layer with it.The first video of our CodeBot 201 tutorial series walks you through defining a domain model for a Fantasy Football app, and using CodeBot to instantly transform the domain model into a complete MongoDB database and REST API: I still think keeping the code in controller isn't necessarily the right thing to do (even with DDD) as long as e.g. Would it be okay to have Service Layer with DDD in such a web app? Then follows the code customer.MakePayment(10) Īfter that we call dbContext.SaveChanges() methodĭbContext tracks the changes and stores the payment - Bingo! In our controller / service we fetch a customer (for example by id) So, in order to make a payment, I imagine, we do the following: (say, we deal with an ASP.NET WebAPI app) With Entity Framework we can eagerly load the entire tree with the result Customer already has all their Payments mapped. The code will be as follows: public class Customer Plus, according to DDD - we keep our logic inside the model - so we have MakePayment method. And that model has one-to-many relation ICollection Payments. So, how I imagine the app without a separate Repository layer.įor example we have Customer model as an Aggregate Root (rich domain model). I'm wondering if we can omit creating Repository Layer in this case? Nothing much was explained with regard to Entity Framework.Įntity Framework 6 & Entity Framework Core already provide Repository/UoW out of the box. Watched a tutorial by Pluralsight in which they mention Repositories and noticed that a repo normally contains basic CRUD operations (create, update, fetch & remove entity). In Domain Driven Design it's common to keep business logic in a rich model. I used to deal with simple apps that have Service Layer containing all of the business logic.
