Geographic Information System (GIS) is coming up with integrated wireless technologies for implementing in real time applications. OpenGIS enables spatial data sharing and system interoperability, which leads to data integrity, timeliness and hinders data replication. The shopping assistant E-Shopping is developed to solve that issue; the "E"envisions: "Everything is Easier for Everybody on Every time". It provides shoppers all information they need to make a convenient shopping by the aid of a shopping digital assistant. E-Shopping does this by providing rich information and services via a network-enabled Pocket PC, giving them direct access to the valuable information quickly and easily. The commercial software's developed for wireless applications do not provide a system in one suite for real time applications. The methodology designed and developed in this study is describing an Open Source wireless system for map visualization, data updating, uploading and retrieving in real time. The concept of portable digital shopping assistant using E-Shopping Solution become popular able to remove human's role and effectively contribute to the development one's business. Open Source software's and freeware packages, e.g. Minnesota Map Server, Apache web server, JBox, PFIP, MYSQL and PHP are the foundation of this study. The integrated system demonstrates that reliable spatial data updating can be done in real-time. It is also able to apply at any other kind of business like: museum, library, tourism places, etc. A thesis submitted in partial fulfillment of the requi,rements for the degree of Master of Engineering, School of Engineering Technology Thesis (M.
