Using this data calculation are done to find the necessary amount of money to be reserved according to regulations.

  While in the previous structure customer data could be traced "account based" in this project "person based" tracing can be accomplished.

  A user can define or modify all credit products used in the system using a web interface. Customer information can be queried using several filters defined by the user and a report for the query can be generated.

  A report can be generated monthly based on the Day Past Due (DPD) periods and products defined by a user.
