Request

Can I have the following information:

The number of times the Service has requested data from the Tesco Clubcard database, "Crucible", run by Dunnhumby Ltd, in each of the last five years, or for as many years as possible.
For each request, the amount of data requested, preferably but not necessarily expressed as a range of dates.
The type of data requested each time - e.g. simple confirmation card was used at a certain time, or a list of items bought, or CCTV data linked to the loyalty database.
The cost of each request.
Please also answer points 1-4 again substituting the Nectar database, run by Loyalty Management Group.
