Architecture framework used is a mix between:

Process ProcessQueue

• N-tier architecture.• Messaging architecture

Component Characteristics

CMS Interface Server

• Provides remote interface.

• Uses CMS APIs.

• Provides a model that generalizes and hides CMS functionality.

CMS Interface Client

Uses the remote interface of CMS interface server.

ComponentsComponent Characteristics

Media Streaming Component

• COTS.

• Streams images, audio and video.

• Maps every resource into a URL.

• Should not have any dependencies on other components.

• Pulls new media files from temporary storage.

Goal Of Decomposition

Modifiability

Performance

Usability

ComponentsComponent Characteristics

Content • Works as a model (MVC) .

• Hides CMS remote interface.

• Provides Object –Oriented model for CMS content.

• Handles Content retrieval and reporting.

• Has a dependency with the streaming subsystem.

Control • Works as controller (MVC).

• Provides application services for client tier.

• Has dependency with Content and File Upload.

Component CharacteristicsFile Upload • COTS.

•Uses HTTP or TCP.

• Writes files to temporary secondary storage.

• Should not have any dependencies on other components.

Java Script Framework

• Runs on client machine as a viewer (MVC).

• Connects asynchronously to service provided by the applications.

• Handles all UI manipulation operations.

Third-Party Libraries

Goal Of Use

Testability

Composability

Loose Coupling

Library PurposeSpring Framework

• Automatic instantiation of objects (Factory).

• Hides details of components’ implementation.

• Paves the way for zero deployment.

AspectJ • Better error handling and reporting techniques.

• Can be used to separate between running the system in normal and debugging modes.

JMS (MOM) Can be used for messaging purposes between components running in different environments to leverage loose coupling.

LibrariesLibrary Purpose

CORBA • An implementation of CORBA could be used to achieve remote invocation capabilities.

• CORBA provides better interoperability.

• Replacements: EJB, RMI and any web service implementation.
