1. What is a row?
A row consists of a finite number of attributes that represent one single entity or item and that are organized pseudo-geometrically as a horizontal belt of data. One row can refer to one particular person, a product, a school, a country or a galaxy.

2. What is a column?
A column, on the other hand, is an arrangement that is interpreted geometrically as a vertical set of data that constitute one particular attribute. One column can represent nationality, or size, age, temperature or price.

3. What is a table?
A table, in databases, is a type of arrangement of data where the many pieces of information that are usually contained in the system, are organized in the bidimensional distribution of matrix, where all the pieces of data stored in the system are either items like “people” or attributes that describe the item like “nationality”. Items are arranged in rows and attributes, in columns.
