By installing applications such as a database system and a user interface programs in the mobile communication terminal, a user forms a database arbitrarily in a form of his/her own preference, input data there, and forms a user interface in a form of their preference. Also, the data managed in the mobile communication terminal may be stored and managed in a mobile communication server system through a wireless network or in a computer through a wired network. The user can download database template a provider provides to the mobile communication terminal from the mobile communication server, use them without generating the database structure for him/herself, and graphs and numerical expressions the user produced using the data of database may be included.
