Technology Matrix Cell Transitions

Summary

• Document/describe (for all possible cell transations) how those steps could be supported/achieved.

Analysis

• Suggestion was made (during the Orlando WGM) to describe the problem-space (type of problem) as well as the path itself. That to determine if different problem spaces lead to different paths through the technology matrix.

Transitions in Dimension 1

	Persistent Representation	Object Representation	Serialized Representation
RIM (generic) Model	RP	RO	RS (XML ITS new!)
RIM Constrained Information Model	CP	CO	CS (XML ITS)
Application Specific Model	AP	AO	AS

The following transitions were deemed to be worthwile of our description:

• RP-RO
  • RO<->RP: ORM software, e.g. Hibernate
• RO-RS
• CP-CO
• CO-CS
• AO-CO
• CO-RO
• AO-RO
• AS-CS
• AS-RS
• CS-RS

Note that diagonal cell transitions (e.g. CO to RS) were decided always to involve (however minimalistically) the adjacent *O square (in this example: RO). Therefore diagonal transitions won't be documented/analysed.

Transitions in Dimension 2

Processing/Business Logic	Object Representation	User Interface
PL	RO	UI
	CO
	AO

The PL-*O tranition issue is described on another wiki page: Processing Logic in RIMBAA Applications. Some thoughts about the UI is discussed on User Interface for RIMBAA Applications.
