Integration of Heterogeneous Bibliographic Information through Data Abstractions.
Abstract
In this study, heterogenous bibliographic information resources from geographically distributed locations are integrated in an automated, unified and controlled way by using abstract data types through the Message-Object Model as defined in Smalltalk-80. A unit of modularity called a 'class' is developed that defines operations to process the data structures encapsulated in the class. The classes focus on processing bibliographic citations obtained from heterogeneous on-line bibliographic data bases into a meta-form with the goal of developing information consistency to simplify further information analysis. Classes developed for the bibliographic citation application can speed program development because the data abstractions can be used in processing generic information such as dates regardless of the bibliographic database source. Prototype classes are developed to show the waste in encapsulating data structures and behaviors for the bibliographic citation application. Data abstractions provides a powerful integration technique that allow the designer to work with bibliographic citation objects without being encumbered with the details of implementation.
