What do you guys think of the "new" data vault approach to design a datawarehouse? Do you agree with what is stated?
Reading some documents about the topic, I somehow disagree with certain statements about the other techniques. They state that using 3NF you have a problem with the datestamp column in the primary key, but we can easily use a surrogate key and use that in the other referencing tables. In my company we are designing for a time-phased approach of data and the ways they use to put the data in a data vault are the same that we use. I don't see anything new about their idea except they kind of thought of a way to put it in a normalized database, nothing very spectacular because we used the same technics without ever heard of data vaults.
