Extending functional databases for use in text-intensive applications
This thesis continues research exploring the benefits of using functional
databases based around the functional data model for advanced database
applications-particularly those supporting investigative systems. This is a
growing generic application domain covering areas such as criminal and military
intelligence, which are characterised by significant data complexity, large data
sets and the need for high performance, interactive use. An experimental
functional database language was developed to provide the requisite semantic
richness. However, heavy use in a practical context has shown that language
extensions and implementation improvements are required-especially in the
crucial areas of string matching and graph traversal. In addition, an
implementation on multiprocessor, parallel architectures is essential to meet the
performance needs arising from existing and projected database sizes in the
chosen application area. [Continues.
