Features

• Mobile Storage Engines - Provides a specialized object-oriented storage engine optimized for persisting structured data as native objects on mobile devices.
• Native Object Databases - Functions as a mobile object database that saves native objects directly to disk, bypassing relational mapping.
• Data Querying - Offers a typed API and query language for filtering, retrieving, and sorting objects within the database.
• Database Change Listeners - Provides utilities for monitoring and reacting to data modifications via real-time change listeners.
• Database Schema Migrations - Automates versioned updates to the local database schema to maintain structural compatibility during application upgrades.
• CRUD Interfaces - Provides a native query interface for performing standard create, read, update, and delete operations.
• Reactive View Bindings - Provides mechanisms that automatically update user interface components in response to underlying database changes.
• Differential Synchronization - Coordinates local and remote states by syncing only incremental data subsets to optimize bandwidth.
• Object-Oriented Databases - Functions as a mobile-optimized database engine that stores data as native objects, eliminating the need for relational mapping.
• Schema-Driven Object Modeling - Provides the ability to define database schemas using object types that align with native programming language structures.
• Zero-Copy Mappings - Maps database records directly to native objects to eliminate the need for traditional object-relational mapping layers.
• Reactive Data Queries - Implements live queries that trigger interface updates automatically when underlying data changes.
• Reactive Databases - Provides a reactive database engine that uses change listeners and streams to trigger automatic user interface updates.
• Real-time Data Synchronization - Coordinates real-time data updates across multiple users and devices via a cloud backend to maintain a consistent state.
• Schema Versioning - Manages database structure updates through a migration system that preserves data during application upgrades.
• Conflict Resolution & Recovery - Implements mechanisms to recover unsynced local data and resolve conflicts during synchronization resets or server rollbacks.
• Database Connection Managers - Manages the initialization and configuration of persistent connections to local data stores.
• Multi-Version Concurrency Control - Implements a multi-version concurrency control model to enable non-blocking read and write operations.
• B-Tree - Utilizes a specialized storage engine that organizes data in B-Tree structures to optimize disk-based lookups.
• Transaction Management - Supports executing data modifications through a transactional model with commit and cancel capabilities.
• C++ Language Bridges - Interfaces Java language structures with a high-performance native C++ database core for improved mobile efficiency.
• Encrypted Database Managers - Offers a secure storage solution that uses hardware-optimized encryption to protect database files from unauthorized local access.
• Encrypted Persistence - Secures application data at rest on local device storage using robust encryption to prevent unauthorized access.
• Database Page Encryption - Secures stored data at rest by encrypting individual database file pages using hardware-optimized encryption.
• Mobile Database Security - Protects sensitive on-device information using hardware-optimized encryption and manages user access through authentication.
• Reactive State Management - Binds database queries to asynchronous event streams to automatically synchronize UI elements with underlying data changes.
• Database Tools - Mobile-first embedded database for local storage.
• Persistence - Mobile database replacement for SQLite.
• Database Management - Modern, object-oriented alternative to traditional SQLite databases.
