  1. What is a row? Row in database describes a set of single item / data structure. For example a staff member called “Bob”.
  2. What is a column? Column in database describes attributes or elements of a row / tuple. For “Bob” example, it can include address and email address.
  3. What is a table? A table is a set of rows sharing the same set of attributes described by the column. I think of it like this: Row (Name), Address, email address Bob , Street A , [email protected] Bro , Street A , [email protected] Ivan , Street Tech, [email protected] In this case the rows (all the staff names) share same attribute structures because the table requires the rows to have address and email address.
