Shooting for the S.T.A.R.S.

The Singapore Land Authority (SLA) handles the registration of property transactions, the issue of new title documents for all properties in Singapore. The Singapore Titles Automated Registry System (STARS), built in Natural and Adabas, captures this information, applies current policy rules, and ensures accurate data for the Land Register, which is guaranteed by law. If this information is inaccurate, or if the updated policy information is not applied, the government is open to legal and financial liability.

The STARS system had accumulated nearly 20 years of data and application customisation. It was imperative to translate the appearance and functionality of the system in a manner that minimised user impact and met performance and integration requirements. We refactored the following legacy workload to Java with Oracle Database: Over 1m lines of Natural code, Over 150 DDMs representing more than 70 Adabase files, and over 700 DCL programs.
