The MDK provides various editors to view and enhance different data resources. Each time you change a resource, you should record the time and type of changes made.
For example, PalEdit lets you create a merged palette for use with several images displayed simultaneously. You could use the database to identify which images share that common palette. Later on, when you incorporate the images into the application, the database identifies that the images share a common palette.
Another use for the database is when you have several different resource types that belong together. For instance, you might want to link a picture of a sperm whale with the sound of waves crashing against a beach. Your database should let you identify which data resources belong together, greatly simplifying the final act of linking them into the controlling application.
