This paper analyzes the applicability of HOPS on describing the workflow patterns, originally published by van der Aalst. The workflow patterns is a widely accepted collection of recurring fragments used for workflow modeling. These patterns can be used for evaluating the capabilities of workflow systems and models. We adopt this, to investigate the application of HOPS. HOPS is a universal specification formalism that can be used to describe cooperating and interacting systems. For this, we provide HOPS implementations of the workflow patterns. This can be used as a basis for future research and to compare HOPS with other formalisms. © 2010 Springer-Verlag Berlin Heidelberg. Source

Database applications allow the analysis of complex and large data sets. Such applications typically offer a lot of analysis functions to reveal all kinds of relations inside the data. Nevertheless end-users quite often face situations where they require viewing certain data or relations that is not easily provided by their existing analysis software. To overcome these situations they need means to create their own user interfaces to data that fit their specific requirements. Our solution is a tool that is easily usable for end users, doesn't require any programming knowledge, but enables them to quickly build a customized user interface to view the data they are specifically interested in. This paper illustrates the usage of our tool in a typical scenario taken from one of our industrial project partners. We show how our tool allows end users to specify interactive applications like spreadsheets. The developed tool is build on top of an OLAP application and is partially based on the Qt Designer. © 2010 Springer-Verlag Berlin Heidelberg. Source
