Multinational Requirements study (May 92 - Aug 92): IT architecture

'The architecture study, carried out in conjunction with Group Technology Unit, has consisted of four areas: platform, database, development tool, and communications. In carrying out this work a number of factors have been taken into account. In summary, these are:

* the system will operate over a number of sites internationally and, potentially, on different hardware and operating system platforms.

* proposals must take into account the "scaleability" factor ie the system will operate in sites with user bases varying from 2/3 to 50 users.

* the technology employed will form the basis for the implementation of other systems within X.

* the proposed solution must provide X with a platform which will allow for changes in system requirements without loss of investment.

In the light of the above factors, the following approach has been adopted:

UNIX machines for larger sites and LAN-based installations for the remaining smaller sites. Various vendors were contacted to discuss their UNIX offerings ...

Further evaluation of IBM and ICL's products is being undertaken with particular emphasis on comparative performance and prices. Group policy and compatibility will also be taken into account during this work. Development of the system will be carried out on a LAN/PC platform while these investigations are proceeding.'
