Patterns and Reference Model
Block Library
• Compositions of pattern implementations that meet requirements of scenarios
• Pattern implementations include blocks and tool-generated code
Architecture Scenarios• Ex. clients submitting one-way service requests via
message queues, SOAP message, transaction spanning message queue and business action, …
Tools• Pattern selection• Patten implementation • Block inclusion• Code generation • Configuration
• Selected patterns of distributed applications
• Meaningful pattern compositions
• A library of configurable, generally applicable blocks • Blocks or block compositions may implement patterns,
but they don’t imply patterns directly
Abstract Code-based

Portal IntegrationPortal Integration
How can users efficiently perform tasks that require access to information that resides in multiple disparate systems?
Create a Portal Application that displays the information retrieved from multiple applications in a unified user interface
![Page 14: Integration Patterns Overview Christopher Baldwin Architect Microsoft EMEA cbaldwin@microsoft.com.](https://reader030.fdocuments.in/reader030/viewer/2022032800/56649d405503460f94a19f05/html5/thumbnails/14.jpg)
Entity IntegrationEntity Integration
How can enterprise data that is redundantly distributed across multiple repositories be effectively maintained by applications?
Introduce an Entity Aggregation layer that provides a logical representation of the entities at an enterprise level with physical connections that support access to the back-end repositories
![Page 15: Integration Patterns Overview Christopher Baldwin Architect Microsoft EMEA cbaldwin@microsoft.com.](https://reader030.fdocuments.in/reader030/viewer/2022032800/56649d405503460f94a19f05/html5/thumbnails/15.jpg)
Process IntegrationProcess Integration
How do you coordinate the execution of a long-running business function that spans multiple disparate applications?
Define a business process model that describes the individual steps that make up the complex business function; Create a separate process manager component that can interpret multiple concurrent instances of this model and that can interact with the existing applications

Business Scenario: ConvergenceBusiness Scenario: Convergence
“In the Convergence pattern, competitors from previously distinct industries start competing to satisfy the requirements of a specific customer set. There are three distinct flavors of this pattern: product, in which product boundaries blur; supplier, in which suppliers become ‘one stop shops’; and complementor, in which companies combine to deliver greater value”
- Profit Patterns, Adrian J. Slywotsky
