Austin, Texas-based UniSQL Inc has developed a database engine and manager, plus development environment, with which it believes it can tap the growing number of integrators that are looking to take advantage of the benefits of object-oriented concepts, but who do not want to abandon investments in traditional relational database systems. UniSQL’s software is said to merge object-oriented and relational approaches in client-server environments. The firm reckons the fruits of its two years’ labour give it a similar lead over relational database vendors trying to add object-oriented features to their existing SQL offerings. Priced from $7,200, the software will be out in March on Sun Microsystems Inc stations.
