In a construction company, a new system has been in place for a few months and now there is a list of possible changes/updates that need to be done. For each of the changes/updates, specify what type of maintenance needs to be done: (a) corrective, (b) adaptive, and (c) perfective. An error in the size of one of the fields has been identified and it needs to be updated status field needs to be changed. The company is expanding into a new type of service and this will require enhancing the system with a new set of tables to support this new service and integrate it with the existing data. The company has to comply with some government regulations. To do this, will require adding a couple of fields to the existing system tables.
