Abstract
Abstract A plurality of program components, which do not have matching interfaces, are combined together automatically to generate a larger new program. An interface specifications' database registers the interface specifications corresponding to each of the program components. A program transformation rule memory stores transformation rules for controlling the reconciliation of the non-matching interface specifications of the program components. A data type memory stores data type transformation rules for reconciling non matching data specifications. A mediating program generator detects a mismatch of the interface specifications between at least two program components which are being combined and generates a mediating program in accordance with the program transformation rule and the data type transformation rule which mediating program enables the two programs and their data to communicate. A components composer generates the larger new program from the program components in the program components' database and the generated mediating program.
