Its main job is to make the data accessible for business functionality and to maintain data consistency. The data layer manages the stored data.It sends the result back to the presentation layer. It will ask the data layer for the current in stock quantity and verify if sufficient quantity is in stock. The business layer receives the desired product and quantity from the frontend. Web shop example: The business functionality to check if a certain product is in stock is hosted on the business layer.For some of the calculations the business logic may require some data, for which it will reach out to the data layer. The business logic computes the answer and returns it to the presentation layer for visualization. It provides interfaces for the presentation layer to trigger certain actions. On the business layer (or application layer) the business functionality is hosted and executed.If you click to add a product to your cart, then the website reaches out to the business layer Web shop example: The website of the web shop is hosted on the presentation layer.Based on the user inputs it triggers the business logic on the business layer. It visualizes the website to the user and accepts their inputs (clicks, typed input, etc.). The presentation layer provides the user interface (UI).One of the most established reference architectures is the 3-tier architecture (sometimes also multi-tier architecture): In this architecture the solution is divided in 3 distinctive layers / tiers. mobile application usually have similar architecture but are much more complex. the development components reduces the level of complexity and keeps the architecture somewhat simple and understandable.Īs an introduction into application architecture, we’ll look at architectures for web application, since this is one of the most common types of applications. It describes the final result once the solution is live and used by actual users it doesn’t describe how you get there. The most common architectures you will see are application architectures, which describe the solution’s blueprint in production. Learn more about Interfaces Application Architecture IT architects use reference architectures as a basis for their project specific architecture and adjust it to the specific needs of the project.

As such they encapsulate well-working and established concepts.Ī reference architecture basically describes the best practices for a certain type of architecture problem. A reference architecture is a generic form of architecture, which contains the typical components but is not specific to an exact use case / project. In this chapter several reference architectures are shown. Since it’s the blueprint for the solution it is crucial for all project members to have some level of understanding of the architecture - especially for technical roles.Īrchitecture is a specification of static and dynamic behaviour of a system in a specific context.

The architecture for a project is designed / developed by IT architect(s). It describes what these components do and how they interact with each other. Timewell an IBM’s SWG Software Group Direct Partner supplies IBM Certified InfoSphere Solution Developers with huge experience to all our clients.IBM Data Science - Best Practices ArchitectureĪrchitecture - more specifically IT architecture - describes the components that together form the solution.
