The fact that data set is more common than dataset is due to the fact that dataset only recently became acceptable, as compared with the original and hence more longstanding data set. Most of it can be downloaded for free from our website. The DataSet is a better choice when building a Web service that will return the retrieved data. For example, New York is a member or element of the sample. In plainer terms, a domain is a grouping of observations that are related while a dataset is the data structure associated with that grouping of observations. Either is fine. Observation Since a DataSet is (in effect) just a collection of DataTable objects, you can return multiple distinct sets of data into a single, and therefore more manageable, object. 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.
