Distributed Multimedia Database Systems

2003

In this paper, the typical problems in distributed multimedia database systems, such as real time requirements, synchronization, QoS specifications, are analyzed. Policies and methods to solve these problems are provided. And various implementation paradigms for distributed systems, such as RPC (remote process call), middleware, Agent, are investigated.

Multimedia Monitoring Database (MMDB)

Isaacs, Kristin, Wall, Jonathan Taylor, Williams, Ashley R. et al. · U.S. Environmental Protection Agency · 2021

Direct monitoring of chemical concentrations in different environmental and biological media is critical to understanding the mechanisms by which human and ecological receptors are exposed to exogenous chemicals. Monitoring data provides evidence of chemical occurrence in different media and can be used to inform exposure assessments. The monitoring data provide required information for parameterization and evaluation of predictive models based on chemical uses, fate and transport, and release or emission processes. Finally, these data are useful in supporting regulatory chemical assessment and decision-making. There are a wide variety of public monitoring data available from existing government programs, historical efforts, public data repositories, and peer-reviewed literature databases. However, these data are difficult to access and analyze in a coordinated manner. Here, data from 20 individual public monitoring data sources were extracted, curated to unique chemical identifiers (EPA’s DSSTox Substance Identifiers, DTXSID) and medium identifiers (e.g., blood, drinking water, indoor air, ambient air, etc.) and harmonized into a sustainable machine-readable data format for support of exposure assessments. The database is provided here as a compressed MySQL dump, containing SQL statements that would recreate MMDB in its entirety.Note that the full uncompressed size of this file is over 300 GB. Users should be aware of space requirements before uncompressing.<br>Curation updates (minor error fixes) for MMDB releases are available at https://doi.org/10.23645/epacomptox.16674298.v5.<br><br>This database accompanies the publication “A Harmonized Chemical Monitoring Database for Support of Exposure Assessments”, by Isaacs K.K., Wall J.T., Williams A.R., Hobbie K.A., Sobus J.R., Ulrich E., Lyons D., Dionisio K.L., Williams A.J., Grulke C., Foster C.A., McCoy J., and Bevington C.

Abstractions for Multimedia Database Systems

Rakow, T.C., Klas, W., Neuhold, E.J. · 1996

In this article we point out important functionality needed to support advanced multimedia applications by a database management system. We introduce a generic datatype to support the implementation of time-dependent media like audio, video, and animation. Besides the demand for specific multimedia datatypes we sketch a taxonomy for the modeling of meta information. Multimedia presentations are made independent from formats and devices similar as data are made independent from physical storage. The developments achieved so far with the AMOS prototype currently under implementation at our institute illustrates the chosen architecture of a multimedia database management system. New Address: Department DBIS, University of Ulm, D-89069 Ulm, e-mail: klas@informatik.uni-ulm.de 1 1 Introduction In advanced multimedia applications, the user accesses the system via a hypermedia authoring and reading environment, e.g. via WWW tools.

Foundations of multimedia database systems

Sherry Marcus, V. S. Subrahmanian · Journal of the ACM · 1996

Though numerous multimedia systems exist in the commercial market today, relatively little work has been done on developing the mathematical foundation of multimedia technology. We attempt to take some initial steps towards the development of a theoretical basis for a multimedia information system. To do so, we develop the motion of a structured multimedia database system. We begin by defining a mathematical model of a media-instance. A media-instance may be thought of as “glue” residing on top of a specific physical media-representation (such as video, audio, documents, etc). Using this “glue”, it is possible to define a general purpose logical query language to query multimedia data. This glue consists of a set of “states” (e.g., video frames, audio tracks, etc.) and “features”, together with relationships between states and/or features. A structured multimedia database system imposes a certain mathematical structures on the set of features/states. Using this notion of a structure, we are able to define indexing structures for processing queries, methods to relax queries when answers do not exist to those queries, as well as sound, complete and terminating procedures to answer such queries (and their relaxations, when appropriate). We show how a media-presentation can be generated by processing a sequence of queries, and furthermore we show that when these queries are extended to include constraints , then these queries can not only generate presentations, but also generate temporal synchronization properties and spatial layout properties for such presentations. We describe the architecture of a prototype multimedia database system based on the principles described in this paper.

Database Support for Multimedia Applications

Michael Ortega‐Binderberger, Kaushik Chakrabarti, Sharad Mehrotra · 2001

The focus in this chapter is on how content-based retrieval of multimedia objects can be integrated into database management systems as a primary access mechanism. In this context, the authors first explore the support provided by existing object-oriented and object-relational systems for building multimedia applications. They then identify limitations of existing systems in supporting content-based retrieval and summarize approaches proposed to address these limitations.

Issues in multimedia database management

M. TAMER ÖZSU · 2003

Multimedia information systems pose significantly different data management requirements than traditional database applications. Some of the multimedia data management issues have been well studied by the database community, but there are other problems that have been largely ignored. In this paper, the generality of multimedia database management is considered and a brief and personal overview of the issues is given.

Multimedia Database: Content and Structure

Samir Kumar Jalal · 2001

Multimedia is a combination of text, graphics, animations, audio and video converted from different formats into digital media. The extension of database application to handle multimedia objects requires synchronization of multiple media data streams. Time-related characteristics of multimedia data should be superimposed on the existing database. This paper will try to focus on several aspects of multimedia databases- its need, structure and method of handling multimedia components in order to render multimedia services to its users.
