Format for photos taken with a Kodak camera. It contains an array of electronic image data that was recorded from the camera's photosensitive elements. It is a RAW image, which offers considerable potential for processing photos to compensate for exposure, white balance, and other parameters without loss of image quality.
This format was used for storing databases on the Pegasus and Palm PDA devices. Besides images, PDB allowed you to store tables, maps, e-books, and other data in a structured way. Today it has become obsolete and has been replaced by more flexible formats with DRM protection.
