• Distributed
architecture
• 10-100x faster than
conventional DB
technology
• Elastic
(Docker/Kubernetes)
• VQL: Similar to SPARQL,
but tailored for SysML
• Adaptable to other
modeling languages
(SysML profiles,
AUTOSAR, Capella, etc)

Performance
• Indexing
• 1.2M model: <20s thanks to delta processing
• 30M repository: <1 hour thanks to delta processing

Performance
• Indexing
• 1.2M model: <20s thanks to delta processing
• 30M repository: <1 hour thanks to delta processing
• Querying
• Complete validation suite: 1.2M model: <1min
• Impact analysis: 30M repository: < 10s
• Custom queries: <0.5s for most queries, even for large models
• At least 10x faster than state-of-the-art graph / linked data databases
(Neo4j, Amazon Neptune, …)

Web-based APIs and User Interfaces
