EDB

eDB

The Embedded Multi-Model Database

SQL + Document + Key-Value + REST + AI queries — all in a single embedded database engine designed for EoS applications.

Four Query Models, One Database

Choose the right query model for each use case — no need to run multiple database engines.

-- Query sensor readings
SELECT device_id, AVG(value) as avg_temp
FROM sensor_readings
WHERE sensor_type = 'temperature'
  AND timestamp > NOW() - INTERVAL '1 hour'
GROUP BY device_id
ORDER BY avg_temp DESC;

Features

Multi-Model

SQL, Document, Key-Value, and REST APIs in a single embedded database. No need to run multiple database engines.

Sub-millisecond Latency

Optimized for embedded storage: B-tree indexes, write-ahead logging, and memory-mapped I/O.

Encryption at Rest

AES-256-GCM encryption for all stored data. Per-table encryption keys managed by the EoS crypto module.

AI-Powered Queries

Natural language queries via the EAI integration. Ask questions in plain English and get structured SQL results.

REST API

Built-in HTTP REST API for remote access. Supports JSON, MessagePack, and CBOR serialization formats.

ACID Compliant

Full ACID transactions with serializable isolation. Safe for concurrent access from multiple EoS tasks.
