DATA PROCESSING

A method and associated system. A user interest rating for a downloadable item stored outside a user device is computed, which includes: maintaining a user profile of a user's preference for types of items that include the downloadable item, identifying one or more characteristics of the downloadable item, and predicting a likely level of user interest for the downloadable item based on the identified characteristics of the downloadable item and the user profile. A data impact rating for the downloadable item is computed, which includes identifying parameters. A download decision, of whether to download the downloadable item, is computed in dependence on the user interest rating for the downloadable item and the data impact rating for the downloadable item.
