Abstract
This paper provides a novel technique for binding database and interactive
graphics systems in small computing systems. Such a technique is
investigated and compared with other binding methods in order to indicate
the essential differences and the corresponding trade-offs. Actually, the
binding method that has been implemented in various works is the
integration of two systems through a specially-designed interface. Firstly,
this approach has been explored and its essential features are explained.
Hence our proposed method is presented. It depends on establishing a
linkage between the two underlying systems using the file management module
of the host operating system. Accordingly, the entire control flow is
included in a batch file. This paper emphasizes the details of the linkage
technique including the linkage mechanism, the manipulation of both
graphical and nongraphical data and the role of the operating system file
manager. In addition, a case study concerning a stock-control example has
been carried out to confirm the applicability of the linkage approach. The
case study represents an implementation of the linkage method for binding a
relational database system and a computer-aided-design graphics package.
Accordingly, various operational conditions have been examined including
multilevel graphical structures. (Autor) 970*Binden versus Integration bei
