Such a large volume of data can be hard to store, but it is a valuable source of data for understanding trends and the way the enterprise functions. This data can be very helpful for making projections that lead to successful strategic decisions, as well as for improving everyday decision making. It’s easy to see why analysis of large quantities of data has become so important to the management of modern enterprises. But OLTP systems are not very well suited to analyzing data. Recently a whole new market has emerged for systems that can provide reliable and fast access for analyzing huge amounts of data—Online Analytic Processing (OLAP).
The company has a number of warehouses from which it distributes items to its stores. The FoodMart IT department collects data about its operations in a SQL Server database and uses Analysis Services to analyze data. Customer Data Information about customers—their names and addresses—is kept in the Customer table in a relational database. In the multidimensional database, you’ll find this information in the Customers dimension. The Customers dimension with a Customers hierarchy enables a user to browse by geographical categories.
2, you see that you can produce different slices, such as sales of all the products to a specific customer, or sales of one product to all customers, and so on. Dimension Attributes But how would you define the space of sales by quarter instead of by month? As long as you have a single attribute (months) for your time dimension, you would have to manually (or in our imaginations) group the months into quarters. Once you’re looking at multiple years, your manual grouping starts to be unwieldy. Multidimensional Space 19 What you need is some way to visualize the months, quarters, and years (and any other kind of division of time, maybe days) in relation to each other—sort of like a ruler enables you to visualize the various divisions of a foot or a yard, and the inches and standard fractions of inches along the way.
