II. System Architectural Design

II. System Architectural Design

A system architecture or systems architecture is the conceptual model that defines the structure, behavior, and more views of a system. An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structure of the system which comprises system components, the externally visible properties of those components, the relationships (e.g. the behavior) between them, and provides a plan from which products can be procured, and systems developed, that will work together to implement the overall system.

The software architecture of a system is the set of structures needed to reason about the system, which comprise software elements, relations among them, and properties of both. In this KA Plus project, our team use two main architecture is Client-Server and Interaction-Oriented Software Architectures (Model-View-Controller (MVC) and Presentation-Abstraction-Control (PAC))

Before read and make requirement clear, our team found that KAP has these attribute :

• 
  The database from mobile application and database from computer must be independence.
  
• 
  In KAP system have a connection among agent in two different devices (mobile and computer).
  
• 
  Data was multi taking and multi viewing.
  
• 
  Use HTTP protocol to connect
  

In order to understand KAP architecture, please see our diagram:

2. System Interface

2.1 PC-Server Interface

KAP-Server Service: A program with Graphic User Interface creates playlist for KAPlus make database. User can add, edit, and create many type of playlist.

2.2 PCs-Client Interface

VLC media player: A video player plays video, receive request and sent status for KAPlus.

KAP-Client: A program help KAPlus find and get database.

2.3Mobile Interface

KAPlus: A mobile application with Graphic User Interface, user can remote karaoke process, selects songs and manager playlist.

III. Component

KAP system will have three main components: KAP-SS, KAPlus and KAP-Client.

1. KAP-SS

KAP-SS run at PC Server, collect all song PC-Server contain to make database for KAP-SS via Playlist file.

2. KAPlus

KAPlus run at mobile, it use playlist file from KAP-SS create to make it own database. It connects with PC-Client via VLC media player and KAP-Client. This is main component of this system.

3. KAP-Client

KAP-Client plays a role like a service program to help KAPlus update database and display mark via request.
