  1. What is a row? A data set representing a single item. In a relational database, it would be a record.
  2. What is a column? A column is a set of data values, all of a single type, in a table. In a relational database, an example would be an address or data of birth.
  3. What is a table? In a relational database, it would be a set of columns and rows. Within a relational database, data is logically organized in a row-and-column format similar to a spreadsheet to form a table. Each row represents a unique record, and each column represents a field in the record.
