Database templates are templates which are used to change the value of a parameter from one value to another, in which the template uses the parameter to change it from its contents to something else, e.g. the template is a kind of database lookup. They are used to do table lookups, value substitutions, and transformation of data. For example, a parameter might convert the two-letter state abbreviation to its full name, or change the two-digit FIPS code for a state to its abbreviation, show the full name for the abbreviation of a Swiss Canton, show the frequency range for a television channel number, etc.
