For that purpose, information on company’s product and sales is highly needed in order to help on decision making process, which expectedly enables company to create value and eventually gain competitive advantage. This research attempts to develop a Data warehouse for PT XXX, which is expected to exhibit useful information for the company without disturbing its operational system. The Data warehouse is developed with Oracle 11g. Apart from that, this research also aims to gather information and knowledge with spatial database. The data mining is conducted by using WEKA application, which compares the algorithm of DBSCAN, K-Means, and EM clustering. Data mining from the spatial data is expected to create area map which indicates sales rate of PT Pos Indonesia’s products. Through this it is hoped that the company may focus more in marketing certain product with particular advantage in one particular area to produce effectiveness. The research outcome indicates that the Data warehouse being developed has already managed to exhibit the receipt report of postal money order (wesel pos), retail stock, as well as retail sales.

Abstract

Credit union has a substantial role in supporting the growth of the national economy. A number of credit Unions implements DSS application to promote and accelerate the process of decision-making by management. DSS can provide ease of calculation, accuracy in the calculation and examination. However, an ITinvestment in DSS application, as well as other investments, is a segment that depletes costs and effort. The cost is calculated from the procurement, and continues during maintenance or during the investment implemented. Thus the implementation of DSS on a credit union needs to be measured whether it is quite fit and gives positive impacts on decision-making by management and on sale.
