EGS-CC DataModeling

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

The DME provides a conceptual data modeling solution which was originally developed by ScopeSET for EGS-CC (European Ground Station Common Core) but has since then been used in other ESA activities such as SVTLC, NewMOD and MARVL.

DME offers the following key functionalities:

  • A lightweight UML and Ecore based datamodeling approach, combined with fully integrated constraint modelling (using OCL) which exceeds the capabilities and usefulness of current complex UML tools
  • Integrated requirements editor and tracing to datamodel elements, ReqIF import (to be tailored dependiung on actual ReqIF)
  • 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
  • PreValidation of DataModels through instantiation in an automatically generated tool significantly raises the quality of the DataModel.
  • Dynamic and notation independent visualization of model data through generated “boxes and lines” diagrams (“Model Explorer”) significantly eases both the learning curve for a new model as well as facilitates communication about models
  • Support for model partitioning, i.e. the splitting of datamodels into separate parts, read-only access to linked external elements
  • Git integration
  • Optional BPMN integration – with tracing cababilities 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.”
