Confidential has to build an application for DHHS to support the child services provided by them in order to serve the people more efficiently. There are Oracle reports which are done previously but the business users and stake holders found them difficult to analyze them. To provide more customization and help the business to utilize the funds more effectively OIT has initiated a Data Warehouse project where the reports and Dashboards generated are multi-dimensional providing the project managers and supervisors identifying the counties and households receiving the benefits, analyzing the demographic information etc. OBIEE 126.96.36.199 is used for developing complex dashboards and reports. This Project enables DHHS to provide efficient services to approximately 250,000 Maine residents
