| Abstract: | |
| We consider the information modeling issues in environments that range
from multidatabase manipulations supporting direct DBMS level interfaces
to multiple database to multisystem applications involving activities among
multiple application systems. Information modeling needs in such environments
go far beyond the use of traditional data models to develop database schemata
or application views.
Besides modeling information regarding individual component systems
and databases, we also need to model activities and interdependencies that
span across the systems. Because of significant interplay between these
different types of information during information management activities
such as query processing and transaction management, a uniform framework
for modeling, and preferably a single language for specifying, all these
types of information is highly desirable. For an example multisystem application,
we demonstrate important aspects of such a uniform and comprehensive modeling
in the SYNTHESIS language. |
