Patterns of Enterprise Application Architecture. Concentrates on Enterprise Application Architecture in the context of a layered architecture. Main sections cover domain logic, web presentations, database interaction, offline concurrency by David Rice and distribution. Database interaction is the largest section with many patterns on object-relational mapping issues.
Although the patterns are focused around the J2EE platform, the patterns are usually equally applicable albeit with a twist to other enterprise application platforms.
Enterprise Integration Patterns. I've increasingly come to the view that integration through asynchronous messaging is one of the most effective ways to integrate disparate enterprise applications. EIP is a foundation collection of patterns for this approach. Microsoft Enterprise Solution Patterns.
Microsoft's first collection of enterprise software patterns. Microsoft Data Patterns. A collection of patterns on data movement: replication and synchronization.
Microsoft Integration Patterns. Microsoft's take on integration patterns. Sections cover strategies for an integration layer, approaches to system connections, and topologies for integration.
Building an object-oriented Domain Model is a popular approach to organizing domain logic. It works particularly well with complex domains. It's downside is that it is difficult to do well. These patterns describe how to think about building and structuring a rich domain model, as well as how to recognize and overcome the real-world obstacles that too-often prevent people from employing the modeling principles they know. See enough domain models, and you see certain kinds of structures repeatedly.
This book was my attempt to capture these commonalities in the form of patterns. In lots of ways it's very much in need of an update, but the basic ideas are still pretty sound. Privacy policy. This eBook was published in the spring of , and has not been updated since then. There is much in the book that remains valuable, but some of the material is outdated. This eBook provides guidance on building cross-platform enterprise apps using Xamarin.
Forms is a cross-platform UI toolkit that allows developers to easily create native user interface layouts that can be shared across platforms, including iOS, Android, and the Universal Windows Platform UWP. The guide provides architectural guidance for developing adaptable, maintainable, and testable Xamarin. Forms enterprise apps. Guidance is provided on how to implement MVVM, dependency injection, navigation, validation, and configuration management, while maintaining loose coupling.
In addition, there's also guidance on performing authentication and authorization with IdentityServer, accessing data from containerized microservices, and unit testing. The guide comes with source code for the eShopOnContainers mobile app , and source code for the eShopOnContainers reference app. The eShopOnContainers mobile app is a cross-platform enterprise app developed using Xamarin. Forms, which connects to a series of containerized microservices known as the eShopOnContainers reference app.
However, the eShopOnContainers mobile app can be configured to consume data from mock services for those who wish to avoid deploying the containerized microservices. Privacy policy. This eBook was published in the spring of , and has not been updated since then.
There is much in the book that remains valuable, but some of the material is outdated. With these in mind, it's important to build apps that can be easily modified or extended over time. Designing for such adaptability can be difficult as it requires an architecture that allows individual parts of the app to be independently developed and tested in isolation without affecting the rest of the app. Many enterprise apps are sufficiently complex to require more than one developer.
It can be a significant challenge to decide how to design an app so that multiple developers can work effectively on different pieces of the app independently, while ensuring that the pieces come together seamlessly when integrated into the app.
The traditional approach to designing and building an app results in what is referred to as a monolithic app, where components are tightly coupled with no clear separation between them. Typically, this monolithic approach leads to apps that are difficult and inefficient to maintain, because it can be difficult to resolve bugs without breaking other components in the app, and it can be difficult to add new features or to replace existing features.
An effective remedy for these challenges is to partition an app into discrete, loosely coupled components that can be easily integrated together into an app. Such an approach offers several benefits:. However, there are many issues that must be resolved when partitioning an app into discrete, loosely coupled components. These include:. This guide provides guidance on these issues, and focuses on the core patterns and architecture for building a cross-platform enterprise app using Xamarin.
The guidance aims to help to produce adaptable, maintainable, and testable code, by addressing common Xamarin. Forms enterprise app development scenarios, and by separating the concerns of presentation, presentation logic, and entities through support for the Model-View-ViewModel MVVM pattern. This guide includes a sample application, eShopOnContainers, that's an online store that includes the following functionality:.
These backend services are implemented as microservices using ASP.
