PROPOSED SOLUTION
OLAP System – is a technology that allows users to carry out complex data analyses with the help of a quick and interactive access to different viewpoints of the information in data warehouses. These different viewpoints are an important characteristic of OLAP, also called multidimensionality. Multidimensional means viewing the data in three or more dimensions. For a database of a Sales Department, these dimensions could be Product, Time, Store and Customer Age. Analyzing data in multiple dimensions is particularly helpful in discovering relationships that cannot be directly deduced from the data itself.
OLAP System Technology basics
To give the reader a feeling of how one should see OLAP, let us look at the following simple example:
Consider a Daily necessities retailer with many shops in different cities and many different styles of product, for example Furniture, Food, and Cleaning supplies. Each shop delivers data daily on quantities sold in Customs Behavior. These data are stored centrally. Now the business analyst wants to follow sales by month, outlet and behavior. These are called dimensions, for example month dimension. If we want to look at the data of these three dimensions and say something significant about them, what we are actually doing is looking at the data stored in a 3-dimensional cube.
Figure 4-1: A 3-dimensional OLAP cube
The following three cubes show us how we can look at, respectively: data on all product type sold in all months in the outlet Hong Kong, data on Potato chip sold in all months in all outlets, and data on all food sold in all outlets in the month April.
Figures 4-2: The OLAP cube looked at from 3 different dimensions
When we combine these three dimensions, we get data on the number of Potato chip sold in the outlet Hong Kong in the month April:
Figure 4-3: The 3 dimensions combined in the OLAP cube
Suppose we want information about the food of the Potato chip or the amount sold, we would have to define new dimensions. This would mean a 4-, 5- or even more-dimensional cube. Of course cubes like this are no longer ‘visible’ to the eye, but in an OLAP-application they are possible!
Components and their functionality

According to [C1], Product, Customer, Vendor data will be stored in the Database of three inside, Data through reorganization, transformation into useful information, the last available to the OLAP system.
Meet strategic objective for supermarket
Reduce inventory costs – through the data warehouse system will be tens of thousands of kinds of goods, sales data and inventory data together through data analysis and classification of knowledge, you can know the stock for some time, did not receive orders for goods, it is received fewer orders for goods and inventory turnover of goods quickly.

Carry out market analysis – The use of OLAP data analysis tools to examine data from a data warehouse to analyze customer buying habits, product composition, and other strategic information. System to the biggest-selling product analysis, then make sure that at the right time, right place at the correct inventory.
For trend analysis- The use of a data warehouse for product variety and inventory trends analysis to select the products need to be supplemented to study customer buying trends, analyze seasonal buying patterns, identify bargains, and its number to respond. To be able to predict seasonal sales, the system must retrieve the data warehouse, 1 million products in more than a year of sales data, and on this basis for analysis.
