What are the Different Application Integration Styles

by

There are a number of different integration styles like

  • Shared database
  • batch file transfer
  • Invoking remote procedures (RPC)
  • Exchanging asynchronous messages over a message oriented middle-ware (MOM).

In Advanced Java, when discussing application integration styles, you typically refer to various approaches or patterns for integrating different software systems or components. Here are some common application integration styles:

  1. Messaging:
    • Message-Oriented Middleware (MOM): Involves using a message broker to facilitate communication between different components or systems by passing messages.
    • Message Queues: Communication happens through message queues, allowing for asynchronous and reliable communication.
  2. Remote Procedure Invocation (RPI):
    • Remote Method Invocation (RMI): Allows objects to invoke methods on remote objects in a distributed system.
    • Java Remote Method Protocol (JRMP): A protocol used by RMI for communication.
  3. Web Services:
    • SOAP (Simple Object Access Protocol): A protocol for exchanging structured information in web services.
    • REST (Representational State Transfer): Architectural style that uses standard HTTP methods for communication.
  4. Enterprise Service Bus (ESB):
    • Middleware: ESB acts as middleware to facilitate communication and integration between different systems.
  5. Data Integration:
    • Batch Processing: Involves processing large volumes of data at scheduled intervals.
    • Real-time Data Integration: Involves integrating and processing data in real-time.
  6. Microservices:
    • Microservices Architecture: Involves developing an application as a collection of small, loosely coupled services that can be developed, deployed, and scaled independently.
  7. File-Based Integration:
    • File Transfer: Involves the exchange of files between systems.
  8. Database Integration:
    • Database Linking: Connecting databases to enable data sharing between them.
  9. API Integration:
    • Application Programming Interface (API): Involves exposing and consuming APIs for communication between different applications.
  10. Event-Driven Architecture:
    • Publish-Subscribe: Components can publish events, and other components can subscribe to receive those events.

These integration styles can be used individually or in combination, depending on the specific requirements of the application or system being developed. The choice of integration style often depends on factors such as scalability, maintainability, and the nature of the systems being integrated.
