R users (mostly beginners) struggle helplessly while dealing with large data sets. The data set lists values for each of the variables, such as height and weight of an object, for each member of the data set. You can select data form tables, create views based on table and ask child rows over relations. A data model encodes the domain knowledge necessary to build a variety of specialized searches of those datasets.
