Editing Data warehouse (section)

===Bottom-up design===
In the ''bottom-up'' approach, [[data mart]]s are first created to provide reporting and analytical capabilities for specific [[business process]]es. These data marts can then be integrated to create a comprehensive data warehouse. The data warehouse bus architecture is primarily an implementation of "the bus", a collection of [[Dimension (data warehouse)#Types|conformed dimension]]s and [[Facts (data warehouse)#Types|conformed fact]]s, which are dimensions that are shared (in a specific way) between facts in two or more data marts.<ref>{{Cite web|url=http://decisionworks.com/2003/09/the-bottom-up-misnomer/|title=The Bottom-Up Misnomer - DecisionWorks Consulting|website=DecisionWorks Consulting|date=17 September 2003|language=en-US|access-date=2016-03-06}}</ref>
