ActiveAndroid
ActiveAndroid est un framework de persistance pour gérer les bases de données SQLite locales sur Android. Il fournit un système d'ORM (Object-Relational Mapping) de type active record qui lie les tables de base de données aux classes, permettant la persistance et la récupération de données sans écrire de SQL manuel.
Le projet se distingue par un outil dédié à la migration de schéma qui met à jour les structures de base de données à l'aide de scripts versionnés chargés depuis les assets de l'application. Il inclut également un framework pour partager le contenu de la base de données entre différentes applications Android via une interface standard de content provider basée sur des URI.
La bibliothèque couvre de larges domaines de capacités, notamment l'ORM pour gérer les relations entre tables et les types de données personnalisés, le traitement de transactions en masse pour l'ingestion de données, et l'initialisation automatisée de la base de données à partir de fichiers pré-remplis. Elle fournit en outre des utilitaires pour les requêtes programmatiques et l'indexation de colonnes afin de gérer la recherche et la récupération de données.
Features
- Active-Record ORMs - Provides an Active Record ORM that binds data access logic directly to model objects.
- Android SQLite Management - Provides a comprehensive persistence framework for managing SQLite databases within the Android ecosystem.
- Schema Migration Scripts - Uses ordered SQL scripts from assets to incrementally update database structures across application versions.
- Database Schema Migrations - Automates the application of versioned updates to database schemas to maintain structural compatibility.
- Object-Relational Mapping Associations - Manages relationships and foreign key associations between database entities at the ORM level.
- Programmatic Query APIs - Retrieves objects from the database using a programmatic API to filter and fetch records.
- Schema Migration Tools - Ships a management tool for updating database structures using versioned scripts loaded from assets.
- Class-to-Table Mappings - Maps classes to tables using annotations to manage primitive data types and primary keys.
- Object Relational Mappings - Provides an object-relational mapping system to bind Android classes to SQLite tables using annotations.
- Content Providers - Implements standardized Android Content Providers to share database content with other applications.
- Inter-App Data Sharing - Exports database records to other Android applications via system-standard content providers.
- URI-Based Content Provisioning - Exposes database records to external applications using a standard provider interface and URI-based access patterns.
- Schema Mappings - Maps application objects to database table columns using metadata annotations.
- Database Schema Migrations - Implements a dedicated tool for updating database schemas through sequential, versioned SQL scripts.
- Custom Type Serializers - Implements serialization and deserialization logic to map complex Java objects to primitive database types.
- Data Type Mappings - Translates application-level complex data types into native database column formats.
- Database Connection Management - Manages the lifecycle and configuration of connections to SQLite database files.
- Database Initializations - Provides mechanisms for initializing the database using pre-populated files from application assets.
- Database Schema Initializations - Provides a mechanism to initialize the database structure and seed it with data from application assets.
- Database Setup - Automates the configuration and initialization of the database layer during application startup.
- Bulk ORM Operations - Provides high-speed bulk insert and update operations for records using batch processing.
- Record Deletion - Provides methods for removing specific database records based on object instances or query criteria.
- Bulk Record Insertions - Supports bulk record insertion by wrapping multiple save operations in a single atomic transaction.
- Column Indexing - Allows marking specific columns as indexed within model definitions to accelerate search and filtering.
- Database ORM - Implements active record style persistence for SQLite databases.
- Persistence - Active record style SQLite persistence.
