A very large dimension.
Monster dimensions require special handling and advanced planning, especially when you are dealing with rapidly changing monster dimensions. Rapidly changing dimensions (i.e., dimensions whose content changes as a result of input errors or changes over time that you are recording in place) arent too much of a challenge when the dimensions are small. However, monster dimensions consume large amounts of maintenance time and CPU cycles because of their size, so you need to plan carefully when you are dealing with them. Lets explore two different methods for managing rapidly changing monster dimensions: first, splitting the dimension, and second, creating a set of non-overlapping value ranges for each rapidly changing attribute and then creating rows that include all possible range combinations.
