This section lists our previous works in which we have made and impact into pragmatic data integration and management.

We are maintaining medical concept dictionaries and ontologies in production grade
relational database management systems (RDBMS.) In the past, RDBMS did not
support transitive relational structures and had therefore been unsuitable for
managing knowledge bases. The revised SQL-99 standard, however, may change
this. In this paper we show that modern RDBMS that support recursive queries
are capable of querying transitive relationships in a generic data model. We
show a simple but efficient indexed representation of transitive closure. We
could confirm that even challenging combined transitive relationships can be
queried in SQL.

The Unified Code for Units of Measure (UCUM) is a standard code system to communicate units of measure between computer systems and between humans and computers. It represents all physical units in the SI (and predecessor) systems, and meticulously incorporates the customary units still in use in the U.S. and few other parts of the world. The UCUM has been adopted in the data interchange standard world including DICOM, GIST consortium, HL7, and HITSP. |

We have designed the Structured Product Label (SPL) specification, an HL7 standard for medicinal product knowledge in both human readable and computer-interpretable format. SPL is the first comprehensive standard of medicinal products and is implemented by the U.S. FDA and all U.S. pharmaceutical industry.
