Volume 5, Number 1 EDITORIAL Dear Readers, We hope you enjoyed reading our last issue of IJIT which was the special issue on "Singapore One" edited by Michael Yap. The second issue on "Singapore One" which was to follow has been delayed, mainly to a heavy schedule of work placed on Daniel Pang, the assistant editor for both issues, and Michael who was recently promoted to Chief Executive of NCB. (Congratulations Michael!). However, the second issue is on the way! In the mean time we have decided to produce a new issue, which has papers contributed by authors from all over the world. Some of the problems they address are not new but the solutions are new. It is gratifying to see that researchers are not just looking at new problems to solve all the time but are paying attention to old problems, which have not found satisfactory solutions. In this category are the papers by; Brenda Cheang, Sherlyn Foo and Andrew Lim on "Vehicle Routing" and the paper by Victor Lee and Sunny Suen on "Distance Learning". There are two papers database technology; one on " Maintaining Transitive Closures of Graphs in SQL" by Gouzhu Dong, Leonid Libkin, Jianwen Su and Limsoon Wong and the other on "Object-Relational Query Translation on Heterogeneous Database Architecture". Both address real problems encountered in modern database systems. The paper on "Distributed Mobile Computing" by Zhonghua Yang, Chengzheng Sun, Abdul Sattar and Yanyan Sun, looks at a growing problem in geographically distributed mobile computing as more and more people adapt to it in the process of globalization. We have one paper from Austria from Werner Winiwarter on " A Personal Email Assistant" which has learning capability. This could be a boon to all of us who are flooded by email messages everyday. I hope you enjoy reading this issue of IJIT. Our future plans for going Online are still on. After the next issue on "Singapore One", due to appear early next year, our journal will go online. We will keep you informed. R. Gay |
