Why are there different system views w/ same name but different suffixes

For example, DBC.Columns and DBC.ColumnsX appear to have the same columns while DBC.ColumnsV and DBC.ColumnsVX also have these columns along w/ 4 additional ones. What are the ohter differences in these views?

Thanks in advance

Views without V/VX are deprecated (and no longer maintained) since TD12 because they're based on the old LATIN Data Dictionary. 

There's is detailed explanation in the Data Dictionary manual:
