Time Structures

A few categorizations of time structures are as follows:

• Sequential vs. Cyclic Sequential: Jan 1, ...., Dec 31 Cyclic: days of the week, months of a year

• Hierarchical/Multiple Resolutions Ex. years $\rightarrow$ months $\rightarrow$ weeks $\rightarrow$ days and so on This allows us to aggregate/disaggregate time at different resolutions It also allows us to visualize different levels of detail
