At Oracle, Rugani focused on carving out new business in the midrange market.
Previously, he worked in sales at Bay Networks, Digital Equipment, and Motorola.
With the Rugani appointment, Menlo Park, California-based Informix is continuing to rebuild its executive ranks. In January, the company snagged Howard Bain, 52, former CFO at software developer Symantec, as its new executive vice president, finance, and chief financial officer.
Informix has moved to position itself for a comeback in recent quarters, shifting its product line to target growth areas.
The firm, which suffered several rocky financial years after a series of setbacks, has struggled to regain profitability by targeting new areas for its database software, including e-commerce, financial analysis, and data warehousing.
Under that new strategy, the firm's fourth-quarter profit more than tripled, beating estimates, bolstered by a 12-percent increase in database software sales.
