Persistence
Dieses Projekt ist eine Bibliothek für Objektpersistenz und eine Abstraktionsschicht für Data-Mapper. Es bietet eine Reihe gemeinsamer Schnittstellen und Basisklassen, die darauf ausgelegt sind, die Domänenlogik von spezifischen Object-Mapper-Implementierungen zu entkoppeln und die Geschäftslogik von der zugrunde liegenden Datenzugriffsschicht zu trennen.
Die Bibliothek enthält ein Tool zur Verwaltung und Migration von Datenbankschemata für das Definieren, Versionieren und Bereitstellen inkrementeller Updates von Datenbankstrukturen in verschiedenen Umgebungen. Sie fungiert zudem als Dokumentendatenbank-Mapper, der Objektzustände für Speicherung und Abruf in strukturierte Dokumentformate übersetzt.
Das System deckt ein breites Spektrum an Persistenzfunktionen ab, einschließlich der Verwaltung von Objektsammlungen und der Möglichkeit, Objekte ohne Aufruf von Konstruktoren zu instanziieren, um den Zustand wiederherzustellen. Zudem bietet es Dienstprogramme für die Versionierung von Datenbankschemata und das Dispatching benutzerdefinierter Ereignisse, damit entkoppelte Komponenten auf Persistenzänderungen reagieren können.
Features
- Object Mappers - Provides an abstraction layer that maps application data models to database structures to simplify storage and retrieval.
- Persistence Abstractions - Implements a comprehensive persistence abstraction layer that decouples domain logic from specific database storage backends.
- Data Abstraction Layers - Defines interfaces that decouple application logic from specific database storage backends.
- Data Persistence and Storage - Implements architectures dedicated to the durable storage and long-term management of object-oriented digital information.
- Generic Base Mapper Interfaces - Provides generic base mapper interfaces to ensure consistent behavior across different object mapping implementations.
- Persistence Provider Interfaces - Provides standardized interfaces that allow the implementation of custom storage backends for the persistence layer.
- Database Schema Migrations - Automates the application of versioned updates to database schemas to maintain structural compatibility with application code.
- Database Schema Managers - Provides a declarative toolset for defining and managing database structures across different environments.
- Object-Document Mappers - Maps application objects to document database structures using translation logic.
- Object Persistence - Defines shared interfaces for saving and retrieving complex objects from persistent data stores.
- Object Persistence Tools - Provides mechanisms for saving and restoring the internal state of language-native objects to and from external storage.
- Schema Version Tracking - Tracks database schema changes by recording unique identifiers of applied updates in a database table.
- Database Schema Migrations - Includes a system for versioning and applying incremental database schema updates to maintain consistency across environments.
- Object-to-Document Mappings - Translates object states into structured document formats for storage and retrieval within document-oriented databases.
- Domain Data Presentation Layers - Implements architectural patterns that separate an application into domain, data, and presentation layers.
- Domain-Persistence Decoupling - Separates business entity definitions from database schemas to allow domain rules to drive the model.
- Document Database Modeling - Provides a framework for mapping application data structures to document-oriented database formats.
- Schema Migration Executors - Applies incremental updates to a database schema to migrate it to a target version without losing data.
- Object Collection Management - Implements specialized methods for handling groups of objects during data persistence operations.
- Reflection-Based Instantiators - Utilizes reflection to instantiate class objects without invoking constructors to restore their state from storage.
- Persistence Event Dispatchers - Dispatches custom signals throughout the application lifecycle to let decoupled components react to persistence changes.
- PHP Event Dispatchers - Implements PHP libraries that dispatch named events to registered listeners for decoupled communication.
