What is Architecture about ?
Business is about creating/selling ‘product’ . . .
A hit t i b t kfl d d t d d tArchitecture is about workflows needed to engender product. . .
Enterprise Architecture is about the design of [optimal] workflows . . .
It is about the

o Producto Datao Monieso Monies
And how they hang together

Thus . . .
Data is needed to ‘condition’ operations on product/componentmoney flows
throughout any system
Data Architecture is necessarily tied to the Business ArchitectureData Architecture is necessarily tied to the Business Architecture
The Business Flow includes ALL processALL processes are conditioned by Datap y
Only some processes are conducted electronically within the IS ‘service subset’
A Data Architecture is required whether or not there are Applications [in an IS environment]
Look at a [necessarily] high level workflow -

A subset
David J.W. Gilmour - TOGAF, Toronto, 23 July 2009Enterprise Architecture - Is Data Architecture in the right place?
A subset – Product flows

This is revisiting an old question
►Data is NOT exclusive to the Information Systems
► It is fundamental to the business workflows
►At the top of the stack we architect business workflows
►By holding it tight to I.S. we alienate ‘the business’
►Only some data is ‘electronically processed’
►All data is used in/by/during business process

■ All initial ‘input’ and final ‘output’ is to ‘people’
