Sophisticated Applications
in SIR
New York Conference 2005
Unsophisticated
I’m the only user
 I’m only go to do this once anyway
 I know what these codes mean
 If anyone wants any of this stuff they
have to come to me anyway
 You can do anything with a spreadsheet

Sophisticated Applications

Other People Use It
– Reliable
– Repeatable

Long Lived
– Changes in People
– Changes in Application

Understand Requirements
– Implementation may not be the problem
Data, Processes and
Interfaces

Database Design
– Driven by data
– Data Analysis from existing/proposed documents
or systems
– Records and Keys
– Coding systems

Processes – who, what, when?
–
–
–
–
Regular Data Input
Standard Tasks
Interfaces to other systems
Queries and analyses
Data, Processes and
Interfaces
