Java and its framework have been used to develop web application. Java is excellent as programming language; however, it takes a relatively large number of time and cost. Recently, a case that requires providing various solutions in a short period of time has been increasing.

We will propose a system with Ruby on Rails that uses Ruby and its framework as one of their solutions. Based on the know-how of constructing Ruby on Rails system, we will provide quick solution and support our customer's competitive strength.

library information system

Next-L Enju that we have adopted is Japan's first open source library information system. Prior to this, system using open source could be found, but library information system itself as source code has not been opened to the public. Leading library and information science officials in Japan have considered its specification and have implemented Next-L Enju. As a result, library information system already practical and covers all functions that are indispensable to library officials.

Moreover, by taking advantages of open source, Next-L Enju can easily customize. If implemented new features are disclosed as open source, it can contribute to the development of library information system of Japan. From this point of view, MIS approves to Next-L Enju project and support introduction as a solution.
