It compares the effectiveness of this object-oriented database to that of a relational database (Ingres) previously used to record the Protestant Cemetery in Rome. It aims to show that object-oriented databases may be more appropriate to the representation of archaeological data, particularly when ...
The management of data has seen a shift from the conventional use of relational database management systems and other models to cater to the complexities. The first is the Object-Oriented Database Management Systemthat tries to incorporate object orientation and database systems. A classification of...
This comprises a declarative relational to object schema mapping process which is implemented during development and a query engine which makes use of the mapping at run-time to allow access to data in the relational database by object oriented access methods. The methodology allows access to data...
Object-oriented database design is not only a simple extension of relational database design. By modeling structure as well as behavior of real-world entities as coherent units, object-oriented database design succeeds in capturing more semantics of applications already in the design phase. The ...
Object-oriented databases follow the fundamental principles of object-oriented programming (OOP). The combination of relational model features (concurrency, transaction, and recovery) with object-oriented principles results in an object-oriented database model. ...
However, for an information system, such as Wheels, a developer would be much more likely to choose a relational rather than an object-oriented database. Relational database technology has dominated the market for many years; object-oriented databases, on the other hand, are relatively recent. ...
In recent years, the classic relational database management systems have been extended with some object oriented features, such as user-defined data types and structured attributes. Some of these extensions were even standardized within SQL.This fact and the comfortable features, tools and ...
Goal of object Goal of object--oriented design is to model a oriented design is to model a process process Goal of relational database design is normalisation Goal of relational database design is normalisation The mapping from objects to tables can be The mapping from objects to tables can be...
Furthermore, it illustrates concrete implementing of the storage of object-oriented relational records in object-relation database. 介绍了在面向对象数据库和关系数据库相结合的对象关系数据库中,实现关系型数据结构和面向对象数据结构的结合及其存储的一种方法,并举例说明对象关系数据库中对象关系数据记录存储的具体...
