Designing database interfaces with DBface
DBface is a toolkit for designing interfaces to object-oriented databases. It provides users with a set of tools for building custom interfaces with minimal programming. This is accomplished by combining techniques from User Interface Management Systems (...
Estimating accesses in partitioned signature file organizations
We show that performance of some basic methods for the partitioning of signature files, namely Quick Filter and Fixed Prefix, can be easily evaluated by means of a closed formula. The approximation is based on well-known results from probability theory, ...
Incremental clustering for dynamic information processing
Clustering of very large document databases is useful for both searching and browsing. The periodic updating of clusters is required due to the dynamic nature of databases. An algorithm for incremental clustering is introduced. The complexity and cost ...
A reappraisal of structured analysis: design in an organizational context
We review Structured Analysis as presented by Yourdon and DeMarco. First, we examine the implicit assumptions embodied in the method about the nature of organizations, work processes, and design. Following this we present the results of an exploratory ...
