DianaDB

DianaDB is the first fully featured DBMS written in Node.js — a column-oriented NoSQL database in TypeScript. It stores documents in a columnar format where every field acts as an index. It supports schema-enforced collections, spatial and time-based queries, cross-database lookups, materialized views that update on the fly, ACID transactions with document-level locking, change subscriptions, migrations, TLS/mTLS, and S3-compatible backup storage.

For agents: DianaDB, a column-oriented NoSQL database written in TypeScript for Node.js, with server install, Docker, security/TLS and config reference docs.

# DianaDB

> DianaDB is the first fully featured DBMS written in Node.js — a column-oriented NoSQL database in TypeScript. It stores documents in a columnar format where every field acts as an index. It supports schema-enforced collections, spatial and time-based queries, cross-database lookups, materialized views that update on the fly, ACID transactions with document-level locking, change subscriptions, migrations, TLS/mTLS, and S3-compatible backup storage.

DianaDB is authored and maintained by Data Bikers Limited (Hong Kong). It is conceptually close to MongoDB — the query language is similar to MQL — but architecturally distinct: columnar storage, mandatory document schemas, and a TypeScript-native ODM. Current release: Server v3.0.0 / ODM v3.0.0. Server 3.0.0 requires ODM >= 3.0.0 for subscriptions (ODM 3.0.0 also works with older servers, so upgrade the ODM first).

## Server

- [Install and Run DianaDB Server](https://diana-db.com/server/linux): Debian and Alpine install, the `diana-db` CLI (start/stop, user, access and backup management), the full config-file / environment-variable reference including TLS, S3 storage and write-ahead log keys, and how snapshots and the write-ahead log keep acknowledged writes durable
- [DianaDB & Docker](https://diana-db.com/server/docker): Debian and Alpine Dockerfiles, entrypoint scripts, `docker run`, and Docker Compose
- [Security](https://diana-db.com/security): TLS/mTLS, AES-256-GCM request encryption with a password-derived key (the password is never transmitted), per-user per-database access levels (1 read, 2 write, 3 manage) and what each allows, token-authenticated subscribers, derived-key user storage, and private S3 storage

## Desktop Application

- [DianaDB Desktop Application](https://diana-db.com/desktop/gui): cross-platform GUI for browsing and managing data, editing schemas and relationships, inspecting materialized views, and testing queries. Linux (AppImage) and Windows builds, currently v1.1.2

## ODM (Node.js client)

- [DianaDB ODM for Node.js](https://diana-db.com/odm/overview): installation, `DianaDb` constructor options (object form and `diana-db://` / `diana-dbs://` connection string), connection and reconnect behaviour, and every client method — connect/disconnect, subscribe/unsubscribe, migrations, transactions, database and collection management, schema reading and locking, views, health, version
- [Schema and Types](https://diana-db.com/odm/schema): document schema definition, all field options (`type`, `required`, `unique`, `mutable`, `lowercase`, `uppercase`, `default`, `get`, `set`, `items`, `reference`, `triggerRemove`, `ttl`, `precision`) with their mutual exclusions (`precision` is optional since 3.0.0), and all eight field types (STRING, NUMBER, BOOLEAN, POSITION, OBJECT_ID, REFERENCE, TIME, ARRAY)
- [Model](https://diana-db.com/odm/model): the `Model` class, its options (including `dianaDb`), and its methods — `init`, `insert`, `find`, `count`, `update`, `remove`, `
