Transaction data representing a transaction to be processed is input through an input terminal. An interface unit assigns the input transaction data a business code identifying the business activities of a company involved in the transaction represented by the transaction data, and a type code identifying an account title classified based on a cost element. A journalizing unit refers to a master information storage unit, and journalizes the transaction data based on the business code and the type code. The journal result is stored in a database accessible from the terminal device of the accounting division.
