The record

Purpose: eDB is an embedded multi-model database for EoS devices with SQL, JSON document, and key-value stores.
SQL: Its SQLite-compatible SQL subset includes CREATE, INSERT, SELECT, UPDATE, DELETE, and JOIN.
Indexes: It uses B-tree indexes for SQL, hash indexes for key-value data, and inverted indexes for document full-text search.
Transactions: The database supports ACID transactions with write-ahead logging and is described as safe across power failures.
Encryption: At-rest encryption is AES-256-GCM, with keys derived from the eBoot TPM measurement.
Storage: Supported storage includes NOR flash, NAND flash, eMMC, SD cards, and volatile RAM.
Limits: The engine footprint is listed as under 64 KB of flash, and the database size is limited by the storage medium but tested to 32 GB.
Integrations: The page says eDB runs as an EoS service task, uses eBoot for encryption keys, and uses EIPC for capability-secured inter-process queries.
License: The product page describes eDB as MIT licensed and developed in the open.
Price: The EmbeddedOS products page describes the ecosystem as open-source, MIT-licensed, and free forever.
Support: The Foundation lists technical support for build failures, board bring-up, toolchain setup, and documentation questions; other enquiries are answered in arrival order.
Security response: The Foundation says it will respond to security reports within 48 hours and follows a 90-day responsible disclosure timeline.
Intended users: The product page presents eDB for EoS applications that need persistent storage, including sensor logs, AI model metadata, configurations, device state, and health records.
