Realm Cocoa
Realm-Cocoa is a NoSQL mobile database engine and reactive object database designed for local data storage on mobile devices. It serves as a non-relational alternative to Core Data and SQLite, storing data as objects rather than tables.
The system functions as an encrypted local store that protects sensitive application data using encryption. It provides reactive data synchronization, allowing application objects and user interfaces to update automatically when the underlying database changes.
Features
- Local Data Stores - Functions as a persistent local data store for managing application information directly on the mobile device.
- Core Data Alternatives - Serves as a non-relational alternative to Core Data and SQLite for simplified mobile data modeling.
- Local Storage Solutions - Offers a robust local storage solution for saving application data on mobile devices.
- Mobile Databases - Provides a high-performance local database engine optimized specifically for mobile application environments.
- NoSQL Databases - Implements a NoSQL data model that stores information as objects instead of relational tables.
- Attribute Proxies - Provides proxy objects that automatically refresh application data when the underlying database records change.
- Reactive Databases - Acts as a reactive database that pushes real-time updates to application objects when data changes.
- Reactive Data Bindings - Implements reactive data bindings that automatically update UI components when the underlying database changes.
- Reactive State Syncing - Automatically synchronizes the user interface with the centralized database state to keep views current.
- Zero-Copy Memory Mappings - Maps database files directly into memory to read data without copying bytes into the application heap.
- Multi-Version Concurrency Control - Utilizes multi-version concurrency control to allow simultaneous reads and writes without locking the database.
- B-Tree - Uses B-Tree structures to organize data for high-performance lookups and sorted range queries.
- Encrypted Database Managers - Implements a database manager that secures the entire database file using AES-256 page-level encryption.
- Encrypted Persistence - Secures application data at rest on local mobile storage using symmetric encryption.
- Data Encryption - Protects sensitive user information by transforming data into unreadable formats during storage.
- Cross-Platform Database Kernels - Employs a shared C++ core engine to maintain consistent database behavior across mobile platforms.
- Database and Storage - A modern mobile database alternative to Core Data and SQLite.
- Database Engines - Modern, fast alternative to Core Data and SQLite.
- Database Libraries - Modern, fast alternative to Core Data and SQLite.
- Database Management - Mobile database for local storage.
- Databases and Search - Fast, mobile-first database for iOS and macOS applications.
