2. The Need for Applications
Why these applications are necessary???
The discussion is focus on the tools and applications that fit into the managed Query and EIS categories.
It is already mentioned that these are easy to use, point-and-click tools that either accept SQL or generate SQL statements to query relational data stored in the warehouse.
Some of these tools and applications can format the retrieved data into easy-to-read report, while others concentrate on the on-screen presentation.

These tools are the preferred choice of the users of business applications such as segment identification, demographic analysis, territory management and customer mailing list.
As the complexity of the question grows, these tools may rapidly become inefficient.
The reporting can be identified into 3 distinct types. They are:
Creation and viewing of standard reports.
Definition and creation of ad hoc reports.
Data exploration.

4. Contd… Creation and viewing of standard reports:
This is today’s main reporting activity.
The routine delivery of reports based on predetermined measures.
Definition and creation of ad hoc reports:
These can be quite complex, and the trend is to off-load this time consuming activity to the users.
As a result, reporting tools that allow mangers and business users to quickly create their own report and get quick answers to business questions are becoming increasingly popular.
Data Exploration:
With the newest wave of business intelligence tools, users can easily “surf” through data without a preset path to quickly uncover business trends or problems.
This is the domain of OLAP tool.
