(6) We have a scenario where we are using pre joining technique (1.5+4+1.5) Assume 1:30 record count ratio between master and detail for retail application. Assume 5 million members in master table. Assume header size of primary key in master table is 20 byte. Assume 50 byte header for master and 120 byte header for detail tables. Then 1. How many members are there in detail table? 2. What will be the storage issue justify by calculating storage with normalization and de- normalization.? 3. What will be net result
