− | | rowspan="2" |An example of an interval variable would be temperature. We can correctly assume that the difference between 70 and 80 degrees is the same as the difference between 80 and 90 degrees. However, the mathematical operations of multiplication and division do not apply to interval variables. For instance, we cannot accurately say that 100 degrees is twice as hot as 50 degrees.
| |
− | Additionally, interval variables often do not have a meaningful zero-point. For example, a temperature of zero degrees (on Celsius and Fahrenheit scales) does not mean a complete absence of heat.

| *Non-relational databases, specifically a database’s key-value stores or key-value pairs, are radically different from this model. Key-value pairs allow you to store several related items in one “row” of data in the same table. We place the word “row” in quotes because a row here is not really the same thing as the row of a relational table. For instance, in a non-relational table for the same bank, each row would contain the customer’s details as well as their account, loan and investment details. All data relating to one customer would be conveniently stored together as one record. | | *Non-relational databases, specifically a database’s key-value stores or key-value pairs, are radically different from this model.
