This is a simple graph database in SQLite, inspired by "SQLite as a document database".
The schema consists of just two structures:
- Nodes - these are any json objects, with the only constraint being that they each contain a unique
idvalue - Edges - these are pairs of node
idvalues, specifying the direction, with an optional json object as connection properties
The create, read, update, and delete functions (.sql files) are complete statements with qmark bindings.
Search templates (.template files) are in Jinja2 format, which can be converted to other template syntaxes relatively easily, with a bit of regex magic (though it would be nice if they could be expressed in a more language-agnostic way).
There are also traversal function templates as native SQLite Common Table Expressions which produce lists of identifiers or return all objects along the path.
- Social networks
- Interest maps/recommendation finders
- To-do / task lists
- Bug trackers
- Customer relationship management (CRM)
- Gantt chart
The Banrai Simple Graph Database and Document Store wraps this core logic with an API service, creating a managed graph database and document store, with additional features not found in any of the public bindings.
