Kimball vs Inmon in data warehouse architecture. Source work effort distribution - source team, data warehouse team, shared Use of operational data stores for source systems - selective, complete Especially for "large" (or potentially large) data warehouses, I favor EDW architecture and a quasi-bottoms-up methodology. With Data Analyzer—the brand-new Office data analysis solution—you can quickly and easily view, analyze, and share business data, giving you the power to make better business decisions. These data marts are eventually integrated together to create a data warehouse using a bus architecture, which consists of conformed dimensions between all the data marts. Inmon is one of the leading proponents of the top-down approach to data warehouse design, in which the data warehouse is designed using a normalized enterprise data model. When it comes to designing a data warehouse for your business, the two most commonly discussed methods are the approaches introduced by Bill Inmon and Ralph Kimball… Initiated by Ralph Kimball, this data warehouse concept follows a bottom-up approach to data warehousearchitecture design in which data marts are formed first based on the business requirements. The Kimball Data Warehouse Methodology was developed by Ralph Kimball, who is widely regarded as the father of the data warehouse. His data warehouse design approach is called dimensional modelling or the Kimball methodology. In the decades since, the five members of the Kimball Group worked to develop, explain, and teach the techniques for dimensional modeling. The dimensional approach, made popular by in Ralph Kimball (website), states that the data warehouse should be modeled using a Dimensional Model (star schema or snowflake). The key sources (operational systems) of data for the data warehouse are analyzed and documented. Ralph Kimball is a renowned author on the subject of data warehousing. Accordingly, his version is "bottom-up." Instead, create a data warehouse so users can run reports off of that. The following article provides an outline of Kimball vs Inmon.

In his books, [Kimball wrote that] a data warehouse is a union of data marts. So the data warehouse ends up being segmented into a number of logically self-contained and consistent data marts, rather than a big and complex centralized model. In the Inmon vision the data warehouse is at the center of the “Corporate Information Factory” (CIF), and the newer DW 2.0, which provides a logical framework for delivering business intelligence (BI) and business management capabilities.
