ORPHEUSDB

OrpheusDB is built on top of a traditional relational database, thus it inherits all of the standard benefits of relational database systems "for free"... OrpheusDB is built as a wrapper on top of traditional database systems, with no modifications to the underlying database. At the same time, OrpheusDB supports an important subset of git commands enabling checkout, commit, init, create_user, config, whoami, ls, drop, and optimize. Lastly, OrpheusDB supports a rich syntax of SQL statements, against either known or unknown version(s) of a particular dataset... OrpheusDB is a database system that supports versioning capabilities. Since OrpheusDB is built on standard relational databases, it inherits much of the same benefits of relational databases, while also compactly storing, keeping track of, and recreating versions on demand.
