DBFlow
DBFlow is an object-relational mapping library for Android that maps Java objects to SQLite databases. It serves as a persistence layer designed to reduce manual boilerplate code through automated database access and entity mapping.
The project distinguishes itself with a type-safe query builder that uses a fluid interface to construct queries with compile-time checks. It provides transparent file-level encryption for securing sensitive data and a reactive wrapper that streams database changes to subscribers for real-time updates.
Additional capabilities include asynchronous query execution to prevent blocking the main application thread and chunk-based pagination for loading large datasets. The library utilizes annotation-based code generation to automate the creation of database plumbing.
