Holography is an upcoming field in physics related technologies and holds promises in data storage. Holography is based upon principles of optics like intereference.

The basic difference between photography and holography is that while in a photograph, only the information about the intensity distribution of light at different points in the area being photographed is recorded, in holography, the information about the phase of light is also recorded. This gives a three-dimensional image which resembles the object.
