Clearly keen to reward young high-flyers – and potential millionaires – the Ilford-based software and services house Sapphire International Plc yesterday presented 15-year-old David Bolton with a free copy of its DataEase database management system; traditionally bundled in UK schools on Research Machines’ Nimbus MS-DOS micros, DataEase is one of several packages that the schoolboy prodigy has used to design his own invoicing, stock control, and sales order applications: Sapphire chief Trevor Baker claimed he would be delighted to see the database kid across the board-room table, but fears that David, who already runs his own company and charges UKP25 an hour for his data processing services, would prefer to remain self-employed.
