The database has a set of variables that store various system details about objects, settings, modes, parameters, and so on. Such a variable is named a system variable. A system variable can be real or virtual. A real system variable stores its own value in a database container. A virtual system variable calculates its own value using another object of the database.

The database object has a unified interface for getting and setting system variables using tagged data technology. The unified interface has the getSysVar() and setSysVar() methods which require a variable name and use resbuf-instances for accessing the variable value. Alternatively, the database object represents the specific methods for some system variables that automatically convert the variable value to the required data type and do not require the variable name. Such methods have the names get#() and set#(), where # is the variable name.
