  2. Description Sky Watcher is a program designed to let a user gain information about star viewing through a web and phone interface. The web interface is for novice users and gives detailed information about viewable night sky objects. The phone interface is for more advanced users allowing them to hear basic viewing info.

  9. Pros and Cons ISSUE CS OO Interface Component Distribution Pro Con Code Reuse Pro Con Voxeo Front End Compatibility Pro Con Bottlenecking Pro Con Data Complexity Pro Con Number of Components/Complexity Con Pro Data Access/Integrity Con Pro Adding New Interfaces Con Pro

  10. Rationale Voxeo, the front end is designed for VXML scripts, so it was easier to implement as a Client-Server to fit this limitation and reduce the processing and complexity of components. The Client Server architecture is more distributed with little bottlenecking issues. The OO design requires a bottleneck built in to pass objects along, there the CS version lets interfaces use their own discrete code. If one interface fails, the other can still theoretically function. Data Integrity became very little concern when the design was fleshed all. All data is pre-rendered and not modifiable by the user. So the components access to them was not going to change them.

  11. Code Compilation The system was mainly built in .php scripts residing on the server and the Voxeo component is also VXML script based. The one component that was compiled is the Adobe Flex based Shockwave Flash web front end.
