A Value Analyzer system is a data-driven computer-facilitated financial model that provides accurate and consistent profitability calculations using account and event data stored in a relational database managed by a relational database management system (RDBMS), wherein the account data comprises attributes of the accounts being measured and the event data comprises attributes of account-related transactions. A selector function uses selection criteria to select accounts and events from the relational database in order to generate a number of inputs for profitability calculations.
