Technical Requirements• Performance and Scalability: services must be

able to serve an unlimited number of users 24/7. Engroup must be designed to be able to run in clustering environment effectively.

• Extensibility: components are designed with loose coupling and high cohesion. Cost of upgrading and extending must be minimal.

Technical Requirements (cont.)• Modularity: Each module code base is

independent of the others. One module can be changed without impacting any other one.

• Security: User access is restricted based on method level of service class.

• Testability: The system is designed to make it easy for writing unit test, integration test.

High Level Architecture• Communication

method between Client and Server are AMF, HTTP protocols.

• Engroup server modules could be integrated with other clients via REST.

http://www.esofthead.com

Engroup Client Platform• Platform is developed

based on eSoftHead framework including an extension of Adobe Cairngorm framework.

• Module architecture follows MVC pattern.

http://www.esofthead.com

Engroup Client Platform (cont.)• Platform manages

Module life cycle. • Platform routes

messages sent from one module to appropriate client channel that then dispatches events to listening modules. It helps the module loose coupling with each others.

Engroup Client Platform (cont.)• Platform and common

API are independent of AIR library.

• Factory pattern is used to separate logic code between platform and specific AIR API → Engroup client can run on both desktop and web environment.

framework and Osgi platform (Equinox) as well.• Platform packages many third-party Java

libraries as Osgi bundles: – Apache libraries.– Chat.– Logging.– XML processing etc.

Engroup server by:– Changing the legacy code base (Limit usage).– Data integration (for example: LDAP).– API - using Enterprise Integration Framework Spring

Engroup Server Platform (cont.)• Each Engroup

module follows OO principles:– Each layer has single

and clear responsibility.

– Extensibility.– No cycle dependency.– Separating interface

and implementation into different packages.
