problem4. Define the term ‘Multimedia database’. What are its major strength and weaknesses?

problem5. What is ‘stream media application’? List two major drawbacks of these types of application.

problem6. Stream media applications, such as image data are highly ‘unstructured’. What is meant by this term? Describe any three metadata attributes which can be used to overcome this problem and to facilitate retrieval from media collections or libraries.

problem7. In Multimedia Databases the simplest, though far from efficient retrieval strategy is to search for the requested data serially, from the first item, until one finds the requested data or until the whole collection has been searched. A much more efficient strategy is to develop a set of indexes to facilitate data retrieval.

i) When is it more efficient to use indexing in searching data items?

ii) On what factor(s) should these indexes be based?

iii) List and briefly describe four (4) types of indexes that can be created and used for media data.
