Subsystem Design

Since the only subsystems in our project were databases, we are unable to describe their structure and behaviour along with the classes needed to implement the responsibilities of the subsystem (and thus were unable to produce sequence diagrams describing the interactions within the subsystems). As specified by the design mechanism for persistency, all the databases (database subsystems) will use an OODBMS (Object Oriented Database Management System). Since our knowledge of databases is limited, we were not able to expand the description of the kind of database to be used.
