  1. Multimedia Databases Ryan Hurd

  2. Types of multimedia data • Text: using a standard language (SGML, HTML) • Graphics: encoded in CGM, postscript • Images: bitmap, JPEG, MPEG • Video: sequenced image data at specified rates • Audio: aural recordings in a string of bits in digitized form

  3. Nature of Multimedia Applications • Repositories: central location for data maintained by DBMS, organized in storage levels • Presentations: delivery of audio and video data, temporarily stored, ‘VCR-like functionality’ • Collaborative: complex design, analyzing data

  4. Management Issues • Modeling: complex objects, wide range of types • Design: still in research • Storage: representation, compression, buffering during I/O, mapping • Queries: techniques need to be modified • Performance: physical limitations, parallel processing

  5. Research Problems • Information Retrieval in Queries: Modeling the content of documents • Multimedia/Hypermedia Data Modeling and Retrieval: Hyperlinks, Used in WWW • Text Retrieval: Use of a thesaurus

  6. Multimedia Database Applications • Documentation and keeping Records • Knowledge distribution • Education and Training • Marketing, Advertisement, Entertainment, Travel • Real-time Control, Monitoring
