The Microsoft Data Warehouse Toolkit, 2nd Edition
Part 1 Requirements, Realities, and Architecture. Chapter 1 Defining Business Requirements. Chapter 3 The Toolset. Facts, as reported by the reporting entity, are said to be at raw level; e. These are called aggregates or summaries or aggregated facts.
The Microsoft Data Warehouse Toolkit
For instance, if there are three BTS in a city, then the facts above can be aggregated from the BTS to the city level in the network dimension. In a dimensional approach , transaction data are partitioned into "facts", which are generally numeric transaction data, and " dimensions ", which are the reference information that gives context to the facts. For example, a sales transaction can be broken up into facts such as the number of products ordered and the total price paid for the products, and into dimensions such as order date, customer name, product number, order ship-to and bill-to locations, and salesperson responsible for receiving the order.
A key advantage of a dimensional approach is that the data warehouse is easier for the user to understand and to use.
Also, the retrieval of data from the data warehouse tends to operate very quickly. Facts are related to the organization's business processes and operational system whereas the dimensions surrounding them contain context about the measurement Kimball, Ralph Another advantage offered by dimensional model is that it does not involve a relational database every time.

Thus, this type of modeling technique is very useful for end-user queries in data warehouse. The model of facts and dimensions can also be understood as data cube. Where the dimensions are the categorical coordinates in a multi-dimensional cube, while the fact is a value corresponding to the coordinates.
The main disadvantages of the dimensional approach are the following: To maintain the integrity of facts and dimensions, loading the data warehouse with data from different operational systems is complicated.
It is difficult to modify the data warehouse structure if the organization adopting the dimensional approach changes the way in which it does business.
Normalized approach[ edit ] In the normalized approach, the data in the data warehouse are stored following, to a degree, database normalization rules.
Tables are grouped together by subject areas that reflect general data categories e.
The normalized structure divides data into entities, which creates several tables in a relational database. When applied in large enterprises the result is dozens of tables that are linked together by a web of joins.ETL load, or the process of moving data from a source system such as.
