Data units selection within sequential database

Majority of data files available on web servers cointains not only various data formats. They are linked together into composition producing sequences that have to be read frame by frame – in a movie mode. Surgery operations are very often recorded on video than stored as a data files in computing centre of the hospital. The multimedia database design methods have to consider many rules that must be integrated to obtain several standards for simplifying the application development and for fast exploration of the product. The paper presents several aspects of the design technique giving a unified composition of the project, modularity of the application and the navigation standards within the product.
