pact on the success of a data warehouse are flexibility and scope of the tools offered to users (Chenoweth, Corral & Demirkan, 2006). It was recognized by Chenoweth, et al. that it is not easy to provide simple tools as well as ad hoc queries and reports (Chenoweth, et al., 2006).

An investigation done by Murtaza indicates that the business client should be the one who drives the implementation process. His investigation further indicates that the organization will not receive the full benefit of the data warehouse until and unless the business user can easily plot a route and fully understand the detailed, summarized and historic data in the warehouse (Murtaza, 1998). The study given by Murtaza indicates that selection of a tool for evaluating the data management system should be reliable and constant with the sophistication of the user (Murtaza, 1998). Therefore, the study concludes that it seems proper for the data management system to have more than one access tool. The three tools that can be used to access data warehouse are:

Standard Reports: The extremely protective option for accessing the data management system diminishes the complexity and vagueness (Chenoweth, et al., 2006). The first option for getting the information of data warehouse is to set the users and to develop and deploy a set of standard reports. Generally, this option is used for making executive decision. An executive report is provided with an easy access to a dashboard of metrics for reviewing on a daily, weekly or monthly basis. This dashboard might include enrollment management metrics in a university setting; for example, graduation rates over time, external data on department rankings, and tuition revenue trends. This option is generally used to offer information to a group of less-advanced customers. They have the need for the same set of standard information each day, week or month.

Standard reports with parameter driven access: The second option is to provide a set of standard queries to the users. This gives the customers the power to select detailed parameters and also to select summary of detailed level data. The customers may look at enrollment trends for one particular department or division or may want to look at the numbers of faculties for one particular year provided by the department. Developing some standard reports and allowing the users to modify those reports by selecting only certain parameters can provide the customers with access to significant amounts of data without writing personalized reports.

Ad hoc access: Ad hoc access query tool allows users to select the tables and data from the fields they wish to select. To meet the customer's data need, users may simply get a flat file of data that can be allowed to analyze the own data in numerous ways. For instance, customers could obtain a flat file of overheads data. The customer can produce their own reports by furnishing it, by other sources, by department, by functional expenditure or by combining them all. The ad hoc query tool might also permit the customers to set their own pReferences of reporting.
