One Category different life span.

Hi Team,

We have a requirement that businesses use one category, i.e., category, and then we define the same category as major and minor( for example, the major category is motor vehicles and the minor category is motor vehicles), but now each category has a different life span. For example, in the motor vehicles category, the life span is 5 years 8 years and 10 years . Our question here is how to define these in the oracle system.

or

can we define major category as motor vehicles, the minor category motor vehicles (5 years), motor vehicles (8 years) and motor vehicles (10 years), and so on or is there any other alternative.
