Data model

A data model (or datamodel) is a set of tables, linked by relationships and is an abstract model that organizes elements of data and standardizes how they relate to one another and to properties of the real world entities.

Data processing

Data processing is, generally, "the collection and manipulation of items of data to produce meaningful information." In this sense it can be considered a subset of information processing, "the change (processing) of information in any manner detectable by an observer." Data processing is distinct from word processing, which is manipulation of text specifically rather than data generally.
