Improved change tracking for software maintenance

The authors demonstrate the usefulness of change tracking information from the maintenance programmer´s perspective. They split the data into logical groups and find the connections between these groups. They describe a method to incorporate problem-solving information in a change tracking database. Problem solving is discussed with regard to structured problem-solving techniques for isolating difficult problems. A relational database structure and queries to access the database are discussed. An example of how the change tracking system supports the maintenance problem-solving process is also included
