title OBJECT-ORIENTED DATA MODELING AND WAREHOUSING TO SUPPORT URBAN DESIGN
source Ph.D. Dissertation, School of Architecture, Carnegie Mellon University
summary All over the world, local authorities are moving towards managing and storing urban data in digital form. But the data storage devices used are heterogeneous and typically include relational database management systems (DBMS), GIS and CAD files. As a result, data are present in different locations on different platforms and under different schemas. This poses a problem for software applications meant to support decision-making in urban design that require input from more than one data source. This dissertation demonstrates how data warehousing—combined with object-oriented data modeling—is able to provide a general solution for this problem. Data warehousing is a technique initially developed for business applications, but is equally useful for urban design: The data warehouse constitutes a communication layer between the urban design applications and data sources. It makes the data available through a unified interface that hides the sources themselves and represents that data in terms of a general-purpose, preferably object-oriented, model. The dissertation also describes an implementation prototype of the data model and the data warehouse. The test case of this research is the city of Makkah in Saudi Arabia, which faces significant urban design and planning issues in connection with the pilgrimage (Hajj) that brings millions of visitors to the city every year.
