A restricting condition extracting unit analyzes an error determination portion included in a program to be analyzed and extracts a restricting condition of a particular variable. A variable categorizing unit analyzes the relation among variables used in an executable statement in the program to be analyzed and categorizes the variables corresponding to the analyzed result. A domain definition extracting unit outputs domain relation information representing a domain to which a plurality of variables belong and the relation among variables that belong to the domain using the output of the restricting condition extracting unit and the variable categorizing unit. The domain definition information is graphically displayed so that the user can easily understand the content thereof.
