Hi I urgently need some precise infos to the following questions..What kind of data will be stored in a big mortgage company data warehouse?What is the size of tables(number of row, column), number of records?Also how do you conduct a dta warehouse testing? steps of warehouse testing?Thanks
What is system conversion? For example, if Bank do system conversion, what does that mean? What are steps to do successful system conversion?
If you source data from a system that you (warehouse team) have no authority to enforce data quality at the source level, how do you handle this? Do you apply data validation just after you stage the data? Or do you enforce it at the “end” of the flow (typically as you’re pushing it into the data mart)? Or do you not enforce validation at all?
Latest Answer : As i believe its At Real-TimeRegards,Ravi Kumar Garreravi_kumar_garre@yahoo.co.in ...
