A.3 Computational Viewpoint Specifications
The overall structure of the computational viewpoint specification of the
PhoneMob system is shown in figure A.11. It contains three high-level pack-
ages. One describes the software architecture of the application. The second
deals with the behavioural aspects of the system. The last one contains the
basic data types used in the specification (which were shown in figure 4.8).
In addition, the model for the complete computational specification has some
associated tag values that determine which transparencies are required for
the system. In this case, the transaction and replication transparencies are
needed (see the engineering specification in section A.4) together with the ac-
