Challenges
The Total Ledger system was designed to receive, process and store data for reporting (Central Bank, etc.) The system was implemented on the Oracle DBMS. The user interface was developed by means of Oracle Forms. User access rights to the resources of the Total Ledger system were regulated using the system of roles, united into role groups and stored in the database. Logging of user actions was tied to roles in the Oracle database. Our solution – is to move from the outdated unsupported technologies to the modern stack.
The additional complexity for some types of tasks is high security and privacy standard.
Job done
- We made an uninterrupted and safe software migration from Oracle Forms to the new app.We provided access to the application from the single sign-on system and the enterprise management system. We also provided a smooth transition from using the application on Oracle Forms to the new application.
- We added new features to credit risk management system for data collection. Now it is possible to upload various types of files and validate their correctness with the help of software.
- Our team organized and tested new forms of calculation of taxes. Previously, the interface was developed on Oracle Forms, now we have migrated to the Web UI.
- We developed an electronic archive. Our team designed a generation system according to the established forms also with a module for presenting data in human readable format.
- We built a new system with the possibility of one-time pre-calculation of data and implement the mechanism of removing irrelevant information.
Results
