- introduced around 1994 by Daniel Schwabe - see A Summary of the OOHDM Methodology
- looks at Web applications as navigational views over an object model
- allows the application of OO software engineering methods to applications involving navigation
- separates the design activities into
- conceptual design
- navigational design
- abstract interface design
- conceptual design
- build a conceptual model of the application domain
- create conceptual classes using aggregation and generalization/specialization hierarchies
- sub-systems, classes and relationships define a conceptual schema
- example - conceptual model for a conference paper review system
- example - conceptual model for a Xerox knowledge base
- navigational design
- describe the navigational structure of a hypermedia application
- define navigational contexts in terms of navigation classes such as nodes, links, indices, and guided tours
- nodes represent logical views on conceptual classes
- different navigational models may be built for the same conceptual schema
- links are derived from conceptual relationships
- model movement in the navigation space independently of the conceptual model
- navigational model may evolve independently from the conceptual
model, simplifying maintenance
- example - navigation class model for a conference paper review system
- example - a navigational context for the conference paper review
system
- example - a navigational context for a Xerox knowledge base
- abstract interface design
- define perceptible objects (e.g. a picture, a city map, etc.) in terms of interface classes
- interface classes are aggregations of
- primitives classes (such as text fields and buttons)
- interface classes
- interface objects map to navigational objects
- interface behavior specifies
- how to handle external and user-generated events
- how communication takes place between interface and navigational objects
