Time Dimension:Generally, to generate dates as per the
requuirement we use date dimension.
If your loading of data in fact table on the basis of
time/date then we use the values of date dimension to
populate the fact.
we take the last date on which the fact is populated. Then
check for the existence of dates for the data to be
populated.ifnot we generate through some stored procedure
or as per requirement.
Eg:Daily,weekly,financial year, calender year, business
year etc.,
