ICL DTS maturity
• Origins - ICL Information Processing Architecture, late
1970’s (?)
• Simple but powerful interworking
– straightforward to add to existing TPMS services
• In heavy use at Inland Revenue from ~1986:
– access to National Tracing System
– movements of taxpayer details between COP regions
• In heavy use at DSS from ~1988
– access to Departmental Central Index etc
• In heavy use at British Gas Trading (Centrica)
– all TP traffic routed by DTS to relevant back end

Integration considerations...
 • Loose or tight linking of systems?
• Enquiry access or updates?
• Data consistency across systems?
• Timeliness of data updates?

• Scheduled availability of the systems?
• Suitable integration points available?
• Whether applications can be amended?
• Privacy and authorisation issues?
• Stateful or Stateless Interactions?
