  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.

  2. A column, as represented in a relational database, is an attribute or field, used to express one type of data, as in the height as an attribute
  3. A table, or relation, shows the relationship between columns and rows sharing the same attributes (height and name). Similar to an excel spreadsheet, but can be accessed by a client or user
