For example, in India financial documentation of a company need to be stored for seven years. That is a huge amount of documentation for a large company. So where will they store this? Traditionally in the past, these documents were stored within a office premises. But now there are document warehouses where a large number of documents can be stored and retrieved quickly. One of the examples of where document storage becomes a huge warehouse activity is in the industry of mobile phone operators.

Imagine a company like Airtel which has hundred and fifteen million subscribers in India where would they store under hundred fifteen million application forms,original signed documents of application forms and retrieve it quickly whenever the telcom regulatry authority asks for it. These are stored in specialised warehouses where records management and document management are the key issues.
The warehouse can also be used to store technology products like back up tapes. Large organisations which depend on information technology store their data in electronic format in tapes and other media. So where will they store this? These materials have to be stored under proper storage conditions and there are warehouses designed to store such technology products as magnetic tapes, backup tapes, CDs, DVDs, etc
