Starlight
Concept
The Starlight information model is uniquely flexible and powerful. Starlight uses an advanced, object-oriented approach that is much more conducive to exploratory information analysis than are typical relational data models. Additionally, the Starlight information model is capable of tightly integrating disparate, multi-format (and multimedia) information and data, enabling their concurrent analysis. Further, the model captures interrelationships among database elements and their properties in a way that more effectively mirrors the true nature of most problem domains than do other approaches.
