Data management apparatus and data distribution system

A data distribution system for allowing a data management apparatus to collect data generated by a plurality of information terminals, and transmit, in accordance with a request from a one of the plurality of information terminals, necessary data to the one of the plurality of information terminals, wherein

• each of the plurality of information terminals includes
• a data generation section configured to generate both ghost data used for reproducing a game process having been executed in accordance with an operation performed by a user of said each of the plurality of information terminals, and data based on score data (hereinafter referred to as score-related data), the score data representing an index indicating a skill of a game based on the ghost data,
• a data transmitter configured to transmit, to the data management apparatus, the ghost data generated by the data generation section and the score-related data based on the ghost data, and
• a request transmitter configured to transmit, to the data management apparatus, a ghost data distribution request for requesting the ghost data, and
• the data management apparatus includes
• a data receiver configured to receive, from the plurality of information terminals, the ghost data, and the score-related data based on the ghost data,
• a database processing section configured to register, in accordance with a definition of a database in which a plurality of score sections are defined based on a value represented by the score data, the ghost data received from the one of the plurality of information terminals into one of the score sections in the database, the one of the score sections corresponding to the score-related data received together with the ghost data, and
• a data transmitter configured to transmit, to a one of the plurality of information terminals, the ghost data for at least one user for which the ghost data is registered so as to be associated with one of the plurality of score sections in the database, in accordance with the ghost data distribution request, among the ghost data stored by the database processing section, when the ghost data distribution request is received from the one of the plurality of information terminals.
