The four core business intelligence(BI) components: Data Feeds , Extract-Transform-Load Process , Data Warehouse and Presentation Layer come together and form a complete BI solution. Each tier plays an important role in keeping the system current and running. As you can probably guess, implementing and maintaining a system like this is not easy and is fairly complex.
Very simple errors in the first tiers could have a ripple effect into the entire system, making pieces of the implementation meaningless. Developing on an existing piece of BI software is not trivial. The BI system has a total of four complex tiers that need to communicate with each other effectively. Adding a business requirement to add another piece of data changes the logic in all four tiers of the implementation. Figure below shows the four different tiers that make up the full BI implementation.
