Applications of Object-oriented Databases to Publishing Systems

The application of object-oriented database has only started. We applied an objeceoriented database “Jasmine* to to au automobile service document publishing system “MASCOT” and confirmed its practibility. The service material is a “hyper document” which includes logical structure and reference structure. The conventional database cannot deal with them easily. To overcome these difficulities, in MASCOT, each node of logical structure is directly associated with its corresponding class and language “Jasmine/c” is directly embedded in the text. The access to a heterogeneous database or the data conversion can be encapsulated by using the procedural attributes and demon. This encapsulation hides the data location and the data unit. from the application programmer . We confirmed Jasmine has the ability to express the object, to manupilate, and to extend, which is required for the repositery of hyper ducument. And we also confirmed that it achieves practical performace even on a workstation, by adopting static binding and cashing method.
