Fundamentals
Description	A multi-model database inspired by OrientDB, supporting graphs, documents, key-value, time-series, and search. Uses RAFT-based replication for high availability.	A cloud-native relational knowledge graph system (RKGS) that models all data as relations in Graph Normal Form and is queried with Rel, a declarative, Datalog-based modeling language. Positioned as a knowledge graph coprocessor for Snowflake, it runs in-account as a Native App on Snowpark Container Services, adding rule-based reasoning, graph analytics, and predictive and prescriptive analytics over data where it already lives. The engine is built in Julia.
