Want to know the quickest way to doom your software development project? Jump right in without a clear, detailed plan.
Think of it like this: Imagine building a house with no blueprints and no architect. Even if you managed to construct something usable, chances are it wouldn’t function well. You probably wouldn’t want to live in that house.
The same is true of business technology. Whether you’re building a house or an enterprise application, you can’t skip the architecture piece. A well-thought-out “blueprint” informs every aspect of an enterprise application, from the user interface to the business impact.
Enterprise application architecture (EAA) defines the structure, interactions, and overarching design of complex enterprise software. Without it, you risk rigid systems, security breaches, and inefficient processes.
Let’s unpack exactly what enterprise application architecture includes, the key principles to deploy it successfully, as well as the tools, methods, and best practices to use for the best chance of success.
What is Application Architecture?
Application architecture refers to a set of rules and patterns that govern the underlying structure of a digital system. The specific elements of the application architecture can vary, depending on the industry, business structure, and project goals. Different types of application architecture often include the following common components.
Presentation Layer
The presentation layer of the EAA informs everything users touch, see, and feel. Web, mobile, and desktop user interfaces are part of this layer of enterprise application architecture. Guiding principles in the presentation layer might specify how information is organized in the app’s menus or where to place certain buttons in the app.
Business Logic Layer
Beneath the presentation layer is the business logic layer. This layer deals with how the app functions. Everything from business rules and workflows to core app functionality form the business logic layer. While it’s not quite as visible as the presentation layer, it’s just as important for users and their experience within the app.
Data Layer
As the name suggests, the data layer of the enterprise application architecture contains data. Clear rules about how data is used, accessed, and managed are important for any enterprise application, and that’s exactly what this layer of architecture handles. Conventions related to databases, data stores, and the data itself fall within this category.
Integration Layer
Today, digital technology is only as helpful as its ability to participate in a company’s broader software ecosystem. The integration layer is responsible for patterns, rules, and structures that enable the application to connect to different systems. These mechanisms could include APIs or middleware that allow the application to interface with other tools.
