What Is Enterprise Application Architecture?
Enterprise Application Architecture refers to the design and structure of software systems. It focuses on creating systems that are reliable, scalable, and able to handle complex tasks efficiently.
It’s the plan that helps different applications, like customer management systems, data storage, and communication tools, connect and function smoothly to support business goals.
This architecture focuses on how different software components interact with each other and with core services like databases and middleware to support business goals efficiently.
🎯 Most enterprise architectures include three basic layers:
Database Layer: Manages low-level components like servers, networks, storage, and middleware.
Business Layer: Sets the rules and logic, such as workflows, data models, and calculations specific to the organization.
Presentation Layer: Defines how users interact with the application, including menus, navigation, and interface components.
Concepts of enterprise architecture are variable, so it will not look the same for each organization. For example, programmers and other technical IT professionals regard enterprise architecture strategies in terms of the infrastructure, application and management components under their control.
Some architectures also include additional layers, like the Functional Layer, which outlines how systems behave based on business rules, or the Application Core Layer, which acts as a bridge between the database and other layers.
Understanding the distinction between platforms and applications is key to building a solid architecture. While platforms provide a foundation for multiple applications to run, applications serve specific business purposes.
