Wrapper-based evolution of legacy information systems
Philippe Thiran, Jean-Luc Hainaut, Geert-Jan Houben, Djamal Benslimane
System evolution most often implies the integration of legacy components, such as databases, with newly developed ones, leading to mixed architectures that suffer from severe heterogeneity problems. For instance, incorporating a new program in a...
Process modeling in Web applications
Marco Brambilla, Stefano Ceri, Piero Fraternali, Ioana Manolescu
While Web applications evolve towards ubiquitous, enterprise-wide or multienterprise information systems, they face new requirements, such as the capability of managing complex processes spanning multiple users and organizations, by interconnecting...
Efficient path conditions in dependence graphs for software safety analysis
Gregor Snelting, Torsten Robschink, Jens Krinke
A new method for software safety analysis is presented which uses program slicing and constraint solving to construct and analyze path conditions, conditions defined on a program's input variables which must hold for information flow between...
