實體框架詞彙表

術語 ui	定義搜索引擎
Code First spa	使用代碼建立實體框架模型。模型能夠面向任何現有數據庫或新數據庫。 .net
上下文設計	表示與數據庫會話的類，用於查詢和保存數據。上下文派生自 DbContext 或 ObjectContext 類。 code
約定 (Code First) orm	實體框架用來根據類推斷模型形狀的規則。
Database First	使用 EF 設計器建立面向現有數據庫的實體框架模型。
預先加載	一種加載相關數據的模式，在這種模式下，對一種實體的查詢會在查詢過程當中也加載相關實體。
EF 設計器	Visual Studio 中的可視化設計器，可用來使用方框和線建立實體框架模型。
Entity	表示客戶、產品和訂單等應用程序數據的類或對象。
實體數據模型	描述實體以及實體間關係的模型。
顯式加載	一種加載相關數據的模式，在此模式下，將經過調用 API 來調用相關對象。
Fluent API	可用於配置 Code First 模型的 API。
外鍵關聯	實體間的一種關聯，其中，表示外鍵的屬性包括在依賴實體的類中（即，Product 包含一個 CategoryId 屬性）。
識別關係	一種關係，其中主體實體的主鍵是依賴實體的主鍵的一部分。在這種關係中，沒有主體實體，依賴實體就不能存在。
獨立關聯	實體間的一種關聯，其中，依賴實體的類中沒有表示外鍵的屬性（即，Product 類包含與 Category 的關係，但沒有 CategoryId 屬性）。實體框架將使用獨立對象來跟蹤這種關係。
延遲加載	一種加載相關數據的模式，在此模式下，訪問導航屬性時將自動加載相關對象。
Model First	使用 EF 設計器建立實體框架模型，隨後使用此模型來建立新數據庫。
導航屬性	引用其餘實體的實體屬性（即，Product 包含 Category 導航屬性，而 Category 包含 Products 導航屬性）。
關係逆反	關係的相對一端，例如，product.Category 和 category.Product。
自跟蹤實體	從代碼生成模板生成的實體，這種實體有助於 N 層開發。
每一個具體類型一張表 (TPC)	一種映射繼承的方法，其中，層次結構中的每一個非抽象類型都映射到數據庫中單獨的表。
每一個層析結構一個表 (TPH)	一種映射繼承的方法，其中，層次結構中的全部類型都映射到數據庫中的同一個表。鑑別器列用於標識每行所關聯的類型。
每一個類型一張表 (TPT)	一種映射繼承的方法，其中，層次結構中全部類型的公共屬性都映射到數據庫中的同一個表，但每一個類型的惟一屬性都映射到單獨的表。
類型發現	對應該是實體框架模型的一部分的類型進行標識的過程。
