Persistence
这是一个对象持久化库和数据映射器抽象层。它提供了一组共享接口和基类，旨在将领域逻辑与特定的对象映射器实现解耦，从而将业务领域层与底层数据访问实现分离开来。
该库包含一个数据库模式管理和迁移工具，用于定义、版本化和部署跨不同环境的数据库结构增量更新。它还可用作文档数据库映射器，将对象状态转换为结构化文档格式以进行存储和检索。
该系统涵盖了广泛的持久化功能，包括对象集合的管理以及在不调用构造函数的情况下实例化对象以恢复状态的能力。它还提供了用于数据库模式版本化和调度自定义事件的实用程序，以允许解耦组件对持久化更改做出反应。
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.
