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.
