2. Name: CMB ADI (CMB Analytics Data Infrastructure Site Deployment Briefing UK)
The Vision to have a single data infrastructure to support multiple business requirements from multiple
business groups with single table structure for multiple countries data are put together in a single data
store, with same data structure. Data access c ontrol layer implemented by database view, governing
data access by countries, regional and global level. The main aim of project is to provide a set of
interface files for the CMB ADI UK deployment created from data sent to the UK BI landing area. The
data will be sourced from incoming files as received from the various source systems rather than
UKDW. This is to enable the interface files to contain data fields which are present on the source files
but not loaded into the UKDW in the current processing.
The proposed physical solution for the CMB ADI project is deployed to the UK BI GRID server rather
SMP server.
