Formation of Big Data
"You don't need to have been involved in the analytics sector for long to have heard some software vendor, consultancy, or service provider say, "We've been doing big data since before it was called big data.""
James, that may be true. These datas are generating from the beginning and it's in an unorganized way. Since there are some limitations in backing up, it does get over written in same tapes again and again. When storage technology/devices becomes cheaper, companies starts storing all the wanted and unwanted datas for name sake and address with the fancy name "Big Data"
