MainframeLarge General Computer
Computer manufacturers such as IBM, Fujitsu, and NEC have a long history in enterprise IT solutions and are particularly strong in large-scale computer systems such as mainframes. Transware's “Caravel™ series” supports companies' DX (Digital Transformation) by automatically converting some or all of these mainframe business systems to Java-based systems, thereby achieving the modernization of legacy systems quickly and efficiently.
