![]() The purpose of this study is to explain and demonstrate the entire logical customer order entry database design (especially, from the manufacturing perspective) based on the core object-oriented database model features (e.g., object, object identity, attributes, methods, encapsulation and message passing, class, class hierarchy and inheritance, and some semantic relationships among objects). Therefore, in order to design structural and behavioral characteristics of the entire customer order entry database effectively, a superior database model, such as an object-oriented database model, should be used as a base. However, for any kind of application, the object-oriented database technology has been proposed as a powerful alternative database technology over the traditional (hierarchical, network, and relational) technologies and semantic database models regarding the database design and application capabilities of its features. Object Id, OID represents an object uniquely in group of objects.Conventionally, like the other systems of the manufacturing resource planning information system, customer order entry databases have also been developed under the traditional database technologies. To keep data independent from application program.Ī primary key identifies in object in a table uniquely. OODBMS handles both data and functions operating on that data. OODBMS stands for Object Oriented DataBase Management System.ĭata is stored as entities defined in tabular format.Īn entity refers to collection of similar items having same definition.Īn class refers to group of objects having common relationships, behaviors and properties. RDBMS stands for Relational DataBase Management System. ![]() RDBMS uses tables to represent data and their relationships whereas OODBMS represents data in form of objects similar to Object Oriented Programming.įollowing are the important differences between RDBMS and OODBMS. ![]() RDBMS and OODBMS are database management systems.
