Embedded Databases — Database Systems

Pocketbase is a backend-as-a-service platform that provides a self-contained, single-binary server for building full-stack applications. It integrates a relational database, authentication, and file storage into one executable process, eliminating the need for external infrastructure or complex server management. The platform distinguishes itself through an embedded database engine that runs directly within the application process and a reactive communication layer that pushes live updates to connected clients. By monitoring internal transaction logs, it synchronizes data across multiple users in real time. It also features a schema-aware data access layer that maps database tables to dynamic objects, allowing for data manipulation without the need for manual migration scripts. The system includes a built-in security layer for managing user accounts, session tokens, and access control rules. It handles binary asset management through a managed storage interface that supports local filesystem storage while maintaining metadata references within the database. The entire request lifecycle is managed through a modular pipeline that processes traffic for authentication and validation.
