We present a concrete case study of a situation where it was necessary to have different data models (documents and graphs) in the same database engine using a common query language. A single aircraft already contains some 6,000,000 parts, not counting components. Any single data model inevitably leads to inefficient queries, though queries are nevertheless crucial for the application.
Rod Smith (IBM Emerging Internet Technologies )
