Project Description :
Scope of the project is to expand the sources data with additional information. Information is
needed for multiple targets. (Crims, RiskPro Etc.,) By centralizing the process on TDB, the
processing occurs efficiently, and we can ensure current target's and new targets may use the
same information in future. Since this database is used by multiple targets, additional data's are
enriched and stored as centralized one. Also, this approach is based on top down approach,
Additional information stored are Investor debt type, Indirect risk credit calculation, Risk sharing
calculation, Stable less stable calculation Etc.,
Roles and responsibilities :
 Analysis of FDD, and creating a low level design document for development and better
understanding for mapping development.
 TDD preparation for maintenance purpose and the complex mapping setup's
