This chapter establishes the relationship between corresponding elements and structures that appear in different views in Volume II. Not all pairwise view combinations have a mapping in this section, and not every element is mapped. The emphasis is on mappings that provide useful insights.
The following table summarizes the mappings in this chapter. The table cells tell which section contains a mapping between the corresponding views on the cell's row and column header.
|Module Decomposition||Module Generalization||Module Uses||Module Layered||C&C Pipe-and-Filter||C&C Shared-Data||C&C Communicating-Processes||Allocation Deployment||Allocation Implementation||Allocation Work Assignment|
|Allocation Work Assignment||4.4||4.4||4.4|
4.1 Mapping Between Module Decomposition View and Module Generalization View
|Generalization View Element||Decomposition View Element||Relation|
|IngestData class||Ingest subsystem||The subsystem contains the named classes and all their child classes. The interface of the Ingest subsystem is provided completely by the union of the interfaces of all the named classes and their children.|
4.2 Mapping Between Module Decomposition View and C&C Shared-Data View
|Shared-Data View Element||Decomposition View Element||Relation|
|DictServ||Data Management subsystem||The named shared-data elements are part of the given subsystem.|
|RPC||Communications and Systems Management Segment|
4.3 Mapping Between Module Decomposition View and C&C Communicating-Processes View
|Communicating-Processes View Element||Decomposition View Element||Relation|
|EcInAuto||Ingest subsystem||The named processes are part of the given subsystem.|
4.4 Mapping Between Module Decomposition View, Module Uses View, Allocation Implementation View, and Allocation Work Assignment View
The segments and subsystems named in the two allocation views and the module uses view are exactly the same elements as those named in the module decomposition view.
[Other mappings omitted.]
 It not necessary or desirable to include mappings between every pair of views. A minimum goal is to establish at least one strong module/C&C mapping and a mapping from allocation views to the views whose elements they allocate.
