ConceptBase.cc vs TypeDB

ConceptBase.cc: Deductive object base for metamodeling, built on O-Telos with Datalog rules and unlimited meta-levels. TypeDB: Strongly typed entity-relation database with TypeQL, polymorphic queries and a Rust core.

key differences

  • ConceptBase.cc is primarily an object database; TypeDB is graph.
  • Licensing: ConceptBase.cc is open source (permissive) (FreeBSD-style license); TypeDB is open source (copyleft) (Mozilla Public License 2.0).
  • TypeDB is built for larger datasets (≤ 10 TB) than ConceptBase.cc (≤ 100 GB).
  • Transactions: ConceptBase.cc offers limited ACID; TypeDB offers full.
  • Only ConceptBase.cc has triggers.
  • Only TypeDB has transactions, secondary indexes, compression, role-based access, online schema changes.
