DOCUMENT INTERCHANGE MODELING WITH THE ZACHMAN FRAMEWORK: NIGERIA’S INSTITUTIONS IN PERSPECTIVE
Nwankwo Wilson*, Olanrewaju B. S. and Olayinka T. C.
This paper is part of a study aimed at evolving a platform-independent distributed document interchange system to ease the challenges associated with the information flow cycle between Institutions of higher learning and their prospective candidates especially during verifying and validating academic documents submitted to such Institutions by the candidates. The first part was the proposition of an interchange framework wherein the basic foundations and principles of document exchange were laid down. This study exploits the Zachman framework for Enterprise and Information Systems Architecture. The proposed model ensures that each Institution could implement its information system in such a way that it could exchange requests and verification information directly with a system owned or managed by another institution over a public network such as the Internet with little or no involvement on the part of the candidates. The model is cost-effective and sustainable in the Nigerian environment owing to its being built on existing infrastructure with ease of integration into an existing independent information system.[Full Text Article]
