Especially, I would like to give my special thanks to Prof. Dr. Mete Eren who show me the way of database. Thanks, Sincerely, Bhuphender INTRODUCTION Axiom Care is a dummy company, using this name as a reference only for this document. There are some assumptions for this company also the detail is covered under company paragraph. COMPANY: The Axiom Care is one of the leading integrated financial services providers worldwide. With nearly 5,000 employees worldwide, the Axiom Care serves approximately 5 million customers in about 10 countries. On the insurance side, Axiom is the market leader in the German market and has a strong international presence. In fiscal 2008 the Axiom Care achieved total revenues of over 12.5 billion Euros. Axiom is also one of the world's largest asset managers, with third-party assets of 70 billion Euros under management at year end 2008. Beyond the quality of our financial performance, a number of other activities and factors are important for the sustainable growth of our competitive strength and company value. These include, but are not limited to, our global diversification, the reduction of complexity, our value-based management approach, and our crucially important employees. ABOUT ME: I am a senior IT Manager in this company. Responsible for Initiates and implements improvements in all areas of IT. Serves as main point of contact on all IT-related matters for the office assigned. Responds/acts on upper-management direction. Identifies and provides standards for gathering information for use in trend analysis and reports information to company management. PROBLEM: The insurance company wants to analyze both the written policies and claims. It wants to see which coverages are most profitable and which are the least. It wants to measure profits over time by covered item type (i.e. kinds of cars and kinds of houses), state, county, demographic profile, underwriter, sales broker and sales region, and events. Both revenues and costs need to be identified and tracked. The company wants to understand what happens during the life of a policy, especially when a claim is processed. Every one of the past attempts at providing strategic information to decision makers was unsatisfactory. The cycle of strategic information provision in the past always revolve in these phases : ,[object Object]

User hopes to find the right answer, if not then return to #1Here are some of the factors relating to the inability to provide strategic information: IT receives too many ad hoc requests, resulting in a large overload. With limited resources, IT is unable to respond to the numerous requests in a timely fashion. Requests are not only too numerous, they also keep changing all the time. The users need more reports to expand and understand the earlier reports. The users find that they get into the spiral of asking for more and more supplementary reports, so they sometimes adapt by asking for every possible combination, which only increases the IT load even further. The users have to depend on IT to provide the information. They are not able to access the information themselves interactively. The information environment ideally suited for making strategic decision making has to be very flexible and conducive for analysis. IT has been unable to provide such an environment. PROPOSED SOLUTION As an IT manager I decided to implement data warehouse in company. There are two main production data sources: all transactions relating to the formulation of policies, and all transactions involved in processing claims. Logic Diagram Of data warehouse: The following four schemas outline the star schema for the insurance application consisting of policy creation and claims processing, where these two major processes are represented both by transaction fact tables and monthly snapshot fact tables. This data warehouse will need to represent a number of heterogeneous coverage types with appropriate combinations of core and custom dimension tables and fact tables. The large insured party and covered item dimensions will need to be decomposed into one or more minidimensions in order to provide reasonable browsing performance and in order to accurately track these slowly changing dimensions.
