Input data
At the moment ‘time-series data links’, ‘subscripting data links’ as well as combinations of these links are supported. A data link is a link of a VENSIM variable element to a database table column.
A subscripting data link (SDL) is used to run one VENSIM simulation for every row parameter in a database table separately. A table with multiple SDLs is used to assign more than one parameter to every independent simulation run (Fig. 1; A).

A time-series data link (TSL) is used to assign a database table column as time dependent variable to a variable element of a VENSIM model (Fig. 1; B). Multiple TSLs of single or multiple database tables may be assigned to a single VENSIM model.
