Invantive Control offers access to data stored in databases and (cloud)application using [[Formulas]]. A formula can retrieve a single value like [[I_EOL_BAL_PDER]] or values for a matrix like using [[I_SQL_SELECT_TABLE]]. Formulas are always recalculated after log on and when synchronization ends. A formula is also recalculated when requested by the user. The data container's cache behaviour determines whether the database or (cloud)application is accessed. For example, on SQL Server each recalculation will retrieve the current value, whereas on cloud applications such as Exact Online typically a previously value cached in memory is used. Assuming that the system administrator did not configure the use of disk caches, the cache contents are always forgotten by reconnecting to the database.
