Description

A complete real-time data logging service that supports collection, consumption, shipping, search, and analysis of logs.

All data is stored inside objects which are linked by so-called link attributes. Objects consist of classes which can be extended and de-extended at runtime. Graphs can be defined with a struct.

Cloud-hosted realtime document store. iOS, Android, and JavaScript clients share one Realtime Database instance and automatically receive updates with the newest data.

WakandaDB is embedded in a server that provides a REST API and a server-side javascript engine to access data
