The benefits of data standardization benefits the organization in various counts including facilitating information exchange and having uniform audit mechanisms, Ravi Raman, Chief Risk Officer, Infosys BPO in an interaction with CIOL's B.V.Shiva Shankar. According to him standardization brings down the data maintenance cost. Excerpts:

CIOL: Being business transparency the watchword, keeping data available for anybody, anywhere, anytime, how do you ensure integrity of data?
Ravi Raman: Information integrity refers to the correctness of information. For example:

o We need assurance that the information we use is true and factual.
o We need assurance that information that we receive is what the sender dispatched to us. Information can be classified as basic or verifiable depending on the impact that a breach in its integrity can have, and the privileges that individuals need to be given to process the information.
To ensure integrity of data all the clients networks are extension of their own logical network i.e. each client area is physically and logically segregated and subsequently no modification of the data is possible as it flows in. To ensure that the correct data flows out, audit mechanisms in the form of transaction monitoring, random checks, four-eye procedures besides system verification process ensure that the integrity of the data is not compromised.

CIOL: Do you think that the time has come to rethink about storage system, and would mirroring of data help?
RR: Data mirroring is the act of copying data from one location to a storage device in real-time. As the data is copied in real-time, the information stored from the original location is always an exact copy of the data from the production device. Data mirroring is useful in the speedy recovery of critical data after a disaster. Data mirroring can be implemented locally or offsite at a completely different location. In the current environment of data having to be available at any point in time, mirroring could be a good albeit a costly option.
