A collection of facts, such as values or measurements is known to be the data. Whatever the data is present it is to be stored for future reference. To store data, the authors need the use of databases like Oracle etc.; these come under traditional databases where the structured data i.e., data that resides in a fixed field within a record or file. The problem comes in storing other form of data i.e., unstructured data e.g., photos and graphic images, videos, streaming instrument data, web pages, pdf files, PowerPoint presentations, emails, blog entries, wikis and word processing documents.
