An information processing device includes: a control section controlling rewriting of a recording device installed ni a vehicle; and a setting section that, on the basis of a first maximum number of times of rewriting that corresponds to a first interval ni which functions of the recording device are guaranteed, sets a second maximum number of times of rewriting ni a second interval that is an interval that is shorter than the first interval.

The control device, which operates due to a processor executing an object-oriented program, backs-up, to a storing section, respective first combinations of elements of a first object in which class structure relating to an application program is defined, and respective second combinations of elements of a second object in which class structure relating to a storage region used by an application program is defined. In a case in which generation of an object is necessary when the program is started, for the first object, the control device reads-out the respective first combinations from the storing section and generates the fist object, and, for the second object, the control device reads-out the respective second combinations from the storing section and generates the second object.

An information processing device receives a request signal, read out a user class or a storage region class the request signal requests, and generates an object corresponding to the read-out class, wherein each user class is a class relating to users and each storage region class is a class relating to storage regions utilized by the users, based on the generated object and the request signal. The information processing device executes a method corresponding to the object, and thereby acquire data corresponding to the request signal. The information processing device outputs the acquired data.
