Abstract

This research provides the study of integration between Location Based Services (LBS) and Online Analytical Processing (OLAP). LBS are mobile service that has the capability to provide real time information based on the user’s location. Geographical Information System (GIS) has been the heart of LBS in order to provide all the functionalities in LBS. Although mostly transparent, GIS provides the basis for most functionality, from services like geocoding, routing, location search to map presentation in LBS. In the Knowledge Discovery realm, Spatial Online Analytical Processing (SOLAP) integrates conventional OLAP with GIS data sets. The addition of GIS provides additional features such as better visualization which enhances decision making. With current trend in system development, it is possible to distribute the data available from these three systems (LBS, GIS, OLAP) in the web. The internet has become the main transport for data and information exchange, and a proper integration framework should be use. The research explains critical issues in data integration such as data modeling, schema integration and query processing strategy. The Semantic Web, a new emerging standard that has been used to manage all information on the internet is adapted throughout the research. The use of semantic web in this work merely focuses on solving data heterogeneity and the usage of ontology as a basis for integrating the two different systems. Guided by the methodology, this research will come out with a framework for the integration, focusing on web data integration and the flexibility for multiple sources integration.
