The topic was: How much data should its data warehouse hold—three, four or six months’ data? Data for statutory reporting like Basel-II, and fraud analysis will typically require five-seven years of data, whereas customer cross-sell will require data for one-three years. While hardware costs have been falling, the same cannot be said for data costs. The next task is to dissect if you need to store unstructured data, for example, Web logs, chats, text, social, voice, etc. But if you want to do profitability analytics, you will need finance, revenue and cost data.
