商品描述

Object-oriented databases were originally developed as an alternative to relational database technology for the representation, storage, and access of non-traditional data forms that were increasingly found in advanced applications of database technology. After much debate regarding object-oriented versus relational database technology, object-oriented extensions were eventually incorporated into relational technology to create object-relational databases. Both object-oriented databases and object-relational databases, collectively known as object databases, provide inherent support for object features, such as object identity, classes, inheritance hierarchies, and associations between classes using object references. This monograph presents the fundamentals of object databases, with a specific focus on conceptual modeling of object database designs. After an introduction to the fundamental concepts of object-oriented data, the monograph provides a review of object-oriented conceptual modeling techniques using side-by-side Enhanced Entity Relationship diagrams and Unified Modeling Language conceptual class diagrams that feature class hierarchies with specialization constraints and object associations. These object-oriented conceptual models provide the basis for introducing case studies that illustrate the use of object features within the design of object-oriented and object-relational databases. For the object-oriented database perspective, the Object Data Management Group data definition language provides a portable, language-independent specification of an object schema, together with an SQL-like object query language. LINQ (Language INtegrated Query) is presented as a case study of an object query language together with its use in the db4o open-source object-oriented database. For the object-relational perspective, the object-relational features of the SQL standard are presented together with an accompanying case study of the object-relational features of Oracle. For completeness of coverage, an appendix provides a mapping of object-oriented conceptual designs to the relational model and its associated constraints.

商品描述(中文翻譯)

物件導向資料庫最初是作為關聯式資料庫技術的替代方案而開發的,用於表示、儲存和存取在資料庫技術的高級應用中越來越常見的非傳統資料形式。在關於物件導向與關聯式資料庫技術的激烈辯論後,物件導向擴展最終被納入關聯式技術中,形成了物件關聯資料庫。物件導向資料庫和物件關聯資料庫統稱為物件資料庫,兩者都內建支援物件特性,如物件身份、類別、繼承層次結構以及使用物件參照連結的類別關聯。

本專著介紹了物件資料庫的基礎知識,特別聚焦於物件資料庫設計的概念建模。在介紹物件導向資料的基本概念後,專著使用並列的增強實體關係圖和統一建模語言的概念類別圖,展示了物件導向概念建模技術,其中包括具有專業約束和物件關聯的類別層次結構。這些物件導向概念模型為引入案例研究提供了基礎,以展示在物件導向和物件關聯資料庫設計中使用物件特性的方法。從物件導向資料庫的角度來看,物件資料管理組織的資料定義語言提供了一個可攜、與語言無關的物件模式規範,以及一個類似SQL的物件查詢語言。LINQ(Language INtegrated Query)被作為一個物件查詢語言的案例研究,並展示了它在開源物件導向資料庫db4o中的應用。從物件關聯的角度來看,介紹了SQL標準的物件關聯特性,並提供了Oracle物件關聯特性的相關案例研究。為了完整性,附錄提供了物件導向概念設計到關聯模型及其相關約束的映射。
