For some users, the right approach to a presentation layer is accessing a structured data framework through Excel, which enables you to perform all of the analyses required.
For many other users, data only becomes relevant when it is presented in a context that is relevant to the task that they are performing, i.e. the data that is relevant for the questions that they require answers to in their daily routines.
Some users have a preference for data that is presented in rows and columns because they are familiar with that from accounting reports. For other users, the information is more intuitive if it includes graphical tools and, for example, images of the products presented in an overview of earnings per product.
Good Business Intelligence is when all of the users of data have their information presented in the format that matches their role and their preferred way of receiving the information.
We achieve the freedom to work with different presentations of data when we use the central Data Warehouse to ensure that the basis for the data is the same and the definitions of the key figures are common for everyone.
