Features

• Cross-Platform Storage Frameworks - Serves as a cross-platform storage framework providing consistent API and storage behavior across multiple operating systems.
• Object-Relational Mapping - Functions as an object-relational mapper linking application classes to database tables for object-based data operations.
• SQLite Databases - Utilizes a relational SQLite engine to handle low-level disk I/O and atomic transactions for persistence.
• Record Management Interfaces - Provides standard create, read, update, and delete operations for managing database records and tables.
• Embedded Database Engines - Functions as an embedded database engine integrated directly into the application process.
• Full Text Search - Indexes and searches text content across multiple languages using integrated tokenizers.
• Full-Text Search Engines - Includes a full-text search engine with language-specific tokenizers for efficient text retrieval across large datasets.
• Object-Relational Mappers - Simplifies database interactions by mapping application classes to SQLite tables.
• Storage Encryption - Provides an integrated encryption layer that secures the database file at rest to prevent unauthorized access.
• Connection Pools - Implements a connection pooling mechanism to coordinate simultaneous read and write operations across multiple threads.
• Transparent Field Compression - Intercepts data access to automatically compress and decompress specific table columns to reduce storage footprint.
• Database Migrations - Allows transferring data between different databases via configuration without manual migration tracking.
• Mobile Storage Engines - Manages local storage on mobile devices with specialized features like schema synchronization and data recovery.
• Database Schema Migrations - Automatically updates the database table structure at runtime by comparing current fields with bound class definitions.
• Connection Pooling - Coordinates simultaneous read and write operations across multiple threads using a connection-pooling model.
• Native Language Querying - Executes database queries and filters using native language integration to eliminate raw string concatenation.
• Schema Synchronizers - Automatically aligns database fields to remain consistent with changes made to bound class definitions.
• Transparent Column Compression - Reduces storage footprints by automatically compressing and decompressing specific table fields.
• Type-Safe Query Builders - Translates native language expressions into SQL queries to ensure type safety and prevent injection attacks.
• Encrypted Database Managers - Secures data at rest using an integrated encryption layer to prevent unauthorized access to the database file.
• SQL Injection Prevention - Prevents SQL injection attacks by using type-safe query generation instead of raw string concatenation.
• Thread-Safe Database Access - Handles multiple simultaneous read and write operations through connection pooling to optimize multi-threaded performance.
• Database Libraries - Efficient mobile database framework for Apple platforms.
