  1. A row: meaning a single structured data item in a table. a database table can be thought of as consisting of rows and columns.

  2. A column: Is a set of data values of a particular simple type, one value for each row of the database. may contain text values, numbers, or even pointers to files in the operating system.

3)A table: flat file database, is a set of data elements (values) using a model of vertical columns and horizontal rows, the cell being the unit where a row and column store our data.

I think this is similar to Exel.
