Spine failed

"HL7 xml "

Have to agree. The size of a patients file was massive. It was never going to work.

Hmmm, just like you then, eh?

Then take all the HL7 xml and wrap it inside...wait for it...more xml! Now it is ready for transport over the network so lets wrap it inside SOAP and then encode the whole thing as HTTP trafic and send.

HTTPS - there are racks of ssl accelerators.

Then they store the whole xml "assembly" as a blob field in a database before breaking it down to convert to a simple sql query. Later on they build up the result into another xml string and send the as a https post to the requesting user's incoming web servers.

Very simple really.

Helps keep us all in a job though !

In my first graduate job for a big s/w house working on a government defence contract the older developers were always telling us of a great problem free success story on a previous contract for the Navy developing system XYZ. A year or so later I went on site and happened to get chatting to the users of XYZ about its benefits, "system XYZ, that heap of tulip, we turned it off on the first afternoon and went back to manual use" !!!

"Hmmm, just like you then, eh?" - oh dear. D minus.

It is interesting that they are so sure of themselves that they published this, in their mythbusters section. (They must be losing their nerve!):

The technical architecture of the Spine is not robust enough to meet the needs of the NHS Care Records Service

NHS Connecting for Health is confident that the Spine will meet the information handling needs of the NHS Care Records Service.

Realistic assessments have been conducted about the volumes of data and traffic that the Spine might have to support.

There have been checks into responsiveness, reliability, resilience and recovery which have been carried out under both routine and full load.

Before the contracts for the Programme were let, we invited architects from all the leading suppliers to assist in developing and reviewing the Spine.

Aspects of the network have since been reviewed by independent organisations including Charteris (regularly used as expert witnesses on technology) and Gartner (market-leading benchmark specialists).

Before new Spine software goes live, it must meet declared performance and capacity targets. Successful completion of these tests is required before a release can go live.

There are also two data centres in each local area, each of which has enough capacity to meet performance targets should one data centre become unavailable.

No there aren't, there are 2 data centres altogether. Unless you class a local area as England.
