Answer / manojdubba
Project architecture is like
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.
