Product development system using common format data

摘要

In a car development system, a control specification development computer transmits Excel-format matching data of a car manufacturer to an XML database computer of an ECU supplier. The XML database computer converts the Excel-format data to XML-format data, and stores the data into an XML database. A software development computer of the ECU supplier requests text-format matching data, and the XML database computer extracts the matching data from the XML database, converts the data to text-format data and then transmits the data to the software development computer. A matching computer of the car manufacturer can likewise store ASAP2-format data into the XML database computer or extract the data from the XML database computer.
