Background

Product line approach: development of a generic platform from which numerous different products can be derived. Example: Nokia’s cell phone line

Goals

Develop web-based feature manager tool

Main elements: Feature Tree Management Product Management Feature Tree Editing Product Definition

Methodology

Development Methodology: Weekly iterations – review current

status, choose stories for next iteration Incremental evolution – code is

always runnableMain tools:

Java over Eclipse Spring MVC framework Dojo/Dijit libraries JSON format Derby database

Architecture

The feature manager tool consists of

Client-side code

Server-side code

Database

Achievements- Server SideReceives requests from the client

and responds accordingly. Data requests for client Update requests

Saves system data in a persistent database

Checks input received from client for errors

Reports errors on server side to client

Includes automatic testing6

Achievements- Client SideFeature Tree ManagementSupports creation of a new feature

treeSupports edit/remove/rename an

existing feature treeDisplays information about selected

feature tree

Conclusions

Web applications are complex Many frameworks and libraries Frequent meetings are vital to the

progress of the project. On a large scale project, appropriate work

methods and infrastructures are crucial for the ongoing success of the project. Repository Code reviews

Project was a great platform for learning new technologies and how a project is executed in the “real world”
