Architecture
1. Source systems: like mainframe,oracle,people soft,db2.
2. Landing tables: these are tables act like source. Used
For easy to access, for backup purpose, as reusable for
Other mappings.
3. Staging tables: from landing tables we extract the data
Into staging tables after all validations done on the data.
4. Dimension/facts: these are the tables those are used for analysis and make decisions by analyzing the data.
5. Aggregation tables: these tables have summarized data
Useful for managers who wants to view monthly wise sales,year wise sales etc.
6. Reporting layer: 4 and 5 phases are useful for reporting developers to generate reports. I hope this answer helps you.

Suppose I am loaded with questions as I am an experienced etl coder, but not an analytical report builder. I am using analysis services to build a cube but am trying to choose the reporting architecture. Can someone please confirm whether or not reporting services (using the business intelligence report) will allow for slicing and dicing, or is it only a static report builder. Also, if I am using the cube browser in analysis services, where can I put the option of non empty so that I dont see records that are blank.?
