實體DAC是德爾福的 ORM,支援 LINQ。它提供了一個強大的框架,允許執行資料庫物件到 Delphi 類的對象關係映射,完全支援封裝、繼承、多態性和其他 OOP 功能。要從資料庫中檢索數據,LINQ 用作資料庫獨立的查詢引擎。 此外,還有一個功能豐富的 ORM 建模工具 -實體開發人員,它允許直覺地創建和編輯 ORM 模型,並透過此模型自動生成 Delphi 實體類。 主要特點: * 資料庫第一,模型-第一代碼-第一開發。使用者在使用實體DAC開發應用程式時能夠使用所有三種方式。 * 具有代碼產生功能的可視化 ORM 模型設計器。實體開發人員允許直觀地創建和編輯 ORM 模型,而無需鍵入一行 XML 代碼或手動描述 Delphi 代碼中的類屬性。它支援創建各種映射,如表拆分、將實體映射到多個表、複雜類型、繼承層次結構等。 * LINQ 查詢。在開發應用程式時使用 ORM 不僅必須加快應用程式本身的開發,還必須統一應用程式代碼,使應用程式獨立於開發應用程式的 SQL 資料庫的具體細節和語法,從而允許無需費力地支援應用程式中的多個資料庫。 * 類映射。資料庫表與 Delphi 類的對象關係映射不僅可以執行到從基本 TEntity 類繼承的類,還可以執行從 TObject 中繼承的自定義類。 * 實體查詢快取。為了提高應用程式性能,EntityDAC 允許緩存元數據、從資料庫載入的所有實體、LINQ 查詢等等。
