| Abstract | Many relational databases store records with columns containing various physical properties of the stored items. However when using these data, the dimension and unit checking is often left to the application logic. In physical calculations the individual terms represent various quantities both those having dimensions and dimensionless. Furthermore the values can be expressed in various units. The dimensions and units are important as a type system that is ensuring correctness and provide information about the meaning of the terms and results of the calculations. This paper presents the design of a working implementation of a subsystem representing physical quantities and units in the PostgreSQL database system. |
