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.
