A company just hired a new plant maintenance manager, and they are concerned about the number of corrupt asset records in the present system. In future they want to prevent this from happening. When implementing the new solution, what is recommended?（）

• A、All maintenance personnel have full access to all records.
• B、All maintenance personnel have read-only access to all data. 
• C、Only a very limited number of personnel have full access to static data records, but all maintenance personnel are able to enter work order data.
• D、Maintenance personnel should not be using the system, and should only write entries on printed work orders and hire input clerks to enter these into the system.
