الشركات التي تستخدم Simple Graph في الولايات المتحدة

It is a simple graph database in SQLite, inspired by "SQLite as a document database". Its schema consists of just two structures: Nodes - these are any json objects, with the only constraint being that they each contain a unique id value and Edges - these are pairs of node id values, specifying the direction, with an optional json object as connection properties.
