Design an editor to edit records of (so far) undisclosed type

• Records are stored in a file (possibly remotely)
• Multiple users can access either locally or remotely - synchronization issues
• Friendly user interface (GUI)
• Determine the major classes, their functionality (public methods) and interactions
• Use informal UML-like diagrams

Notes:

• Think in terms of nouns, not verbs
• Do not consider implementation issues yet
• Design so that the pieces can be tested independently
• About the vi editor and ed
• Separate the editor from it user interface
• Separate the file from an editing session: several sessions for one file?
• What are the capabilities of class EditableFile that represents a file of records of undisclosed type?
       Which are type independent?
• What capabilities are added for an editing session?
• Separate the command processor from the user interface
• What are the capabilities of a command processor?
