EGS-CC DataModeling

Design and implementation of a DataModel Editor (DME) for the European Ground Station Common Core (EGS-CC) project.

The DME provides a conceptual data modeling solution which was originally developed by ScopeSET for EGS-CC, but has since also been used in other ESA activities such as SVTLC, NewMOD, and MARVL.

DME offers the following key functionalities:

• A lightweight UML and Ecore based data modeling approach, combined with fully integrated constraint modeling (using OCL), which exceeds the capabilities and usefulness of current complex UML tools
• Integrated requirements editor and tracing to datamodel elements, with ReqIF import
• QUDV and Category support
• Powerful report generation (ICD-like documents, HTML reference reports, etc.)
• Various exports to Ecore, XSD, XMI, etc.
• Model comparison / diff report
• Pre-validation of DataModels through instantiation in an automatically generated tool, significantly raising the quality of the DataModel
• Dynamic and notation-independent visualization of model data through generated “boxes and lines” diagrams (“Model Explorer”), easing the learning curve for a new model while also facilitating communication about models
• Support for model partitioning, i.e. splitting datamodels into separate parts with read-only access to linked external elements
• Git integration
• Optional BPMN integration – with tracing capabilities between the BPM and the DataModel

Quote from a tool user: “I like it a lot, mainly because it is one of the few custom-made software projects that worked exactly as the user needs it and could be used without any problems.”
