Object-oriented databases have been initially constructed instead to relational database expertise for the illustration, garage, and entry of non-traditional information varieties that have been more and more present in complex purposes of database expertise. After a lot debate relating to object-oriented as opposed to relational database know-how, object-oriented extensions have been finally integrated into relational know-how to create object-relational databases. either object-oriented databases and object-relational databases, jointly often called item databases, supply inherent help for item beneficial properties, resembling item identification, periods, inheritance hierarchies, and institutions among sessions utilizing item references. This monograph offers the basics of item databases, with a selected specialise in conceptual modeling of item database designs. After an creation to the basic techniques of object-oriented info, the monograph presents a evaluate of object-oriented conceptual modeling ideas utilizing side-by-side greater Entity dating diagrams and Unified Modeling Language conceptual type diagrams that function category hierarchies with specialization constraints and item institutions. those object-oriented conceptual types give you the foundation for introducing case reviews that illustrate using item positive factors in the layout of object-oriented and object-relational databases. For the object-oriented database point of view, the thing information administration crew facts definition language offers a transportable, language-independent specification of an item schema, including an SQL-like item question language. LINQ (Language built-in question) is gifted as a case learn of an item question language including its use within the db4o open-source object-oriented database. For the object-relational point of view, the object-relational beneficial properties of the SQL common are offered including an accompanying case learn of the object-relational beneficial properties of Oracle. For completeness of insurance, an appendix offers a mapping of object-oriented conceptual designs to the relational version and its linked constraints. desk of Contents: checklist of Figures / checklist of Tables / advent to item Databases / Object-Oriented Databases / Object-Relational Databases

Based on “Database Models," by S. Urban in Encyclopedia of Electrical and Electronics Engineering, John G. Webster (editor); Copyright ©1999 John G. Webster. This material is used by permission of John Wiley & Sons, Inc. homogeneous collections. An instance of a category subclass must be an instance of at least one of its superclasses but may not necessarily be a member of all of its superclasses. 22 illustrates the notational convention for categories together with the different types of constraints on categorization.

Both forms of inheritance can be used in combination to achieve a form of multiple inheritance: class subclassName extends superclassName: interfaceName ( . . ) { . . }; where subclassName inherits the state and behavior of superclassName and inherits the behavior of interfaceName. Detailed examples of ODL are provided throughout the next section, which illustrates how to map object-oriented conceptual models to the ODL. This section uses the side-by-side illustrations from Chapter 1 to map the similar concepts from the EER and UML diagrams into an object-oriented schema expressed in the ODL.
