An architecture for automated software maintenance

We developed an assembly line to implement certain specific changes in a stockbroking system written in COBOL with embedded SQL. The changes were proposed by the maintenance team of the system. Using our architecture, it took a few hours to implement the conditional transformations from the code examples we obtained from the maintenance team. Then we could carry out the tasks completely automated. We report on the transformations, their implementation and the architecture we used. It is the intention of the company that owns COBOL/SQL to use our architecture for similar tasks. This study was carried out in order to give the company that owns the code an indication of the effort it takes, the development process of the components that carry out such tasks, and the process to change software using our architecture
