Evaluation and Optimization of ActiveRecord to implement the Personalized Software Service Platform

To implement the personalized software service platform (YouFree), we use the Ruby on Rails Framework. Ruby on Rails is an excellent Web application development framework, usable for developing fast and agile web applications. It offers a number of integrated technologies and increases the productivity of web application. However, there were some weak points of ActiveRecord on Rails like limitation of find method, lazy loading problem, and so on. In this paper, we qualitatively evaluate the weak points of ActiveRecord. And we optimize the ActiveRecord to implement the YouFree. From these considerations, we can implement the more efficient YouFree system.

A Method for Distributed Personal Contents Management

This paper describes a method for managing, visualizing and searching personal contents distributed on the desktop and the multiple Web sites. Personal Web server in this system enables users to access their contents from the remote sites, so users need not upload them to the public Web server. We propose unified contents access methods for the various contents from the multiple sources and a visualization method to manage personal contents effectively. With unified contents access methods and the visualization method, all contents are accessible through the same interface and users can use them regardless of contents types or sources. To provide the up-to-date information in the personal contents management system, we implemented the file system/database synchronization engine.
