Previous work with spatial database systems has dealt mostly with two dimensions and more with implementation than with design issues. This dissertation deals with the formal design of three- dimensional spatial database systems and with the need for abstraction in the design. Use of abstraction in the formal design of data models allows a database system developer to consider the comprehensive needs of users at an ideal level unencumbered by implementation details. The dissertation also presents a set of robust three- dimensional geometric primitives that could form the core of a discrete dat...
