The future of Object-Oriented and Extended Databases

This is a multi-part message in MIME format. --------------7CDA97B183D9A85BBCF935A9 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Dear database professional, dear IS/IT professional, This is my final call for paticipation in a study about object-oriented DBMSs. I still need more feedback, so I hope you can afford spending some minutes for a colleague who depends on your good will and support, and maybe you can even spread a word or pass along a copy of the attached survey. I am an engineer from Austria and currently working on my Masters thesis in Information Systems at Hawaii Pacific University. The attached survey is the cornerstone of my professional paper and of great importance to the success of my work. The topic of my study is: An Assessment of Object-Oriented and Object-Relational Database Management Systems as the Evolutionary Successor to the Relational Model I will provide my results and findings as downloadable documents on my Web page (PS, PDF, HTML) by the end of this year. Please return the enclosed survey as soon as you can (email attachment). I can ensure you that your contribution will be kept completely confidential. Thank you once again for your participation and support, I do appreciate your gesture. With compliments, Gernot Schmied _______________________________________________________________ Dipl.-Ing.
