Macintosh Workstations

Abstract

OOP, GUI, AND LIBRARY WORKSTATION SOFTWARE. Digital Equipment Corporation (DEC) recently awarded large grants to the University of California and Pennsylvania State University jointly to link the massive bibliographic databases of both institutions together, in spite of varying hardware platforms and geography. At the workstation level, the University of California will create interfaces based on DECwindows, a form of the X Windows interface. The online bibliographic systems of Berkeley and Perm State handle 200,000 to 300,000 requests per week, and currently run on an IBM 3090 in California and a DEC VAX 9000 system in Pennsylvania. This interest in bibliographic interfaces has grown rapidly in the last few years thanks to hardware developments putting more computing muscle on the desktop for librarians, their programmers, and ultimately their patrons. Recent manifestations of graphic interfaces have appeared in many libraries as HyperCard shells built as intermediaries to mainframe bibliographic software. This grant by DEC indicates that this sort of work on graphic interfaces in libraries and the system offices on campuses has not gone without notice by major vendors. With the recent explosion in the number of graphic interfaces, it is important to review these tools and their basis in object oriented programming (OOP).
