    OverCASE

    OverCASE

    A cross-platform integrated CASE system

    An integrated CASE system that: • Supports multiple views and stages of project development – from keeping track of reference documentation to analysis/design modelling, to project implementation, roll-out and tracking the project-related issues. • Supports distributed development of projects by multiple participants, while proactively enforcing access control rules and auditing changes. • Is available on all platforms where development takes place (Windows, Unix/Linux, MacOS, Solaris, etc.) • Offers ideological and conceptual integrity across all facilities. By adapting a new approach to CASE tool architecture (integration at repository level and developing a component-based CASE system instead of a monolithic tool) an entirely new species of tools can be brought into a useful existence – an integrated environment where all project-related activities can be performed efficiently.

    Provenance in NetLogo

    This tool can trace, capture, query and visualize the dependency provenance in NetLogo. It consists of four main components: a source code analyzer used to automatically add probes to the model's source code, a NetLogo extension for capturing the provenance traces generated from probes, a non-preprocessing (NP) provenance slicing technique for computing provenance slices using provenance traces, and a visualization component for visualizing the provenance slices. It is compatible with NetLogo version 5.0.3.
