MonetDB vs VelocityDB: What are the differences?
Developers describe MonetDB as "Column-store database". MonetDB innovates at all layers of a DBMS, e.g. a storage model based on vertical fragmentation, a modern CPU-tuned query execution architecture, automatic and self-tuning indexes, run-time query optimization, and a modular software architecture. On the other hand, VelocityDB is detailed as "A NoSQL Object Database, extended as Graph Database is VelocityGraph". It is a C# .NET NoSQL Object Database that can be Embedded/Distributed, extended as Graph Database is VelocityGraph. It supports both embedded and distributed deployments.
MonetDB and VelocityDB can be categorized as "Databases" tools.
