  1. A Row is a record, a data set representing a single item, eg a person could be considered a row.
  2. A column is an attribute or field, a labelled element that corresponds to a value relating to which row its on, eg if we are using the person example for the row, then some columns could be weight, height, age, etc.
  3. A table is a set of rows and columns that are relation to each other. Using the person example a table would be many rows representing many different people listing all of their attributes as columns.
