The company System Andersson is developing systems for controlling materials and production in industries. They want to add a new service, where parts of those systems are accessible through cell phones. In this paper we are investigating which technology are best suited for this kind of application. And then we describe how we are developing a prototype fort this application, based upon that technology. After investigating technologies such as Java ME, Microsoft Silverlight, and web applications we settled upon building the system as a web application, customized for a mobile environment. To build a web page which is readable by many different cell phones we use the markup-languages which are developed for cell phones. We put much effort in reading about the standards and recommendations for the mobile web, produced by the organizations W3C and OMA. It's also very important that one consider the limitations of cell phones, such as the small screens, their limited performance and their limited means of input and navigation. Finally we are very thorough in our testing on several cell phones created by different manufacturers and with different operating systems and web browsers. On the server we are running ASP.NET, with a database using Microsoft SQL Server, since this was a request from the company. The development is made in C#. We reach a fully operational application with the functions that the company has requested. We got functions for handling orders, changing jobs, supply management, listing employees, and more. We also got a class for generating and rendering of lists and tables for easy and customizable lists for small screens. The application has support for several users with a secure login function. We have also created a system running as a service in Microsoft Windows, which is regularly sending messages, in the form of e-mails to the users of the mobile application. The messages contain user defined reminders, e.g. that the factory is running low on a certain material. The message system is well integrated with the rest of the system, in which one can list the active reminders, edit them or create new ones. Overall this has been an interesting and successful project.
