    Notes: Abstract Databases were introduced to remove redundancy from conventional file systems and encouragesharing, which resulted in update anomalies when information was modified. With presentations (movies) sharing clips (sequence of frames), continuous display becomes challenging as well. Continuous display requires the system to retrieve the information with no disruptions or delays (hiccups) once a display is initiated. To ensure a continuous display using a multi-disk hardware platform, a video object is striped into subobjects. The system enforces a regular schedule on retrieval of each subobject by controlling the placement of the subobjects across the disks. Now if different presentations share subobjects, each presentation will enforce its own restrictions on the placement of the data, resulting in an irregular schedule. We investigate approaches to render a schedule regular for two alternative display paradigms: Demand and Data driven.

    An experimental object-based sharing system for networked databases (1996)

    Notes: Abstract. An approach and mechanism for the transparent sharing of objects in an environment of interconnected (networked), autonomous database systems is presented. An experimental prototype system has been designed and implemented, and an analysis of its performance conducted. Previous approaches to sharing in this environment typically rely on the use of a global, integrated conceptual database schema; users and applications must pose queries at this new level of abstraction to access remote information. By contrast, our approach provides a mechanism that allows users to import remote objects directly into their local database transparently; access to remote objects is virtually the same as access to local objects. The experimental prototype system that has been designed and implemented is based on the Iris and Omega object-based database management systems; this system supports the sharing of data and meta-data objects (information units) as well as units of behavior. The results of experiments conducted to evaluate the performance of our mechanism demonstrate the feasibility of database transparent object sharing in a federated environment, and provide insight into the performance overhead and tradeoffs involved.

    Staggered striping: A flexible technique to display continuous media (1995)

    Notes: Abstract During the past decade, information technology has evolved to where it is economically viable to store and retrieve continuous media data types, e.g., audio and video objects. Systems that support this data type are expected to play a major role in many applications including library information systems, entertainment technology, and educational applications. The objects of this new data type should be retrieved at a pre-specified bandwidth. If an object is retrieved at a rate lower than its pre-specified bandwidth then its display will suffer from frequent disruptions and delays termed hiccups. This paper describes staggered striping as a novel technique to support a hiccup-free retrieval of continuous media data types. Its design is based on a multidisk architecture. It is a flexible technique that can support media types whose bandwidth requirements are either lower or higher than the bandwidth of a single disk. Its design allows a system to scale to thousands of disk drives as its incurred overhead is fixed and does not increase as a function of additional disk drives.

    Design of Multi-User Editing Servers for Continuous Media (2000)

    Notes: Abstract Based on a fifteen month investigation of a post production facilities for both the entertainment industry and broadcasters, we identified a number of challenges with the design and implementation of a server in support of multiple editing stations. These include, how to: share the same content among multiple editors, support continuous display of the edited content for each editor, support complex editing operations, compute the set of changes (deltas) proposed by an editor, compare the deltas proposed by multiple editors, etc. It is beyond the focus of this paper to report on each challenge and its related solutions. Instead, we focus on one challenge, namely how to support continuous display of the edited content for each editors, and techniques for physical organization of data to address this challenge.

    Mitra: A Scalable Continuous Media Server (1997)

    Notes: Abstract Mitra is a scalable storage manager that supports the display of continuous media data types, e.g., audio and video clips. It is a software based system that employs off-the-shelf hardware components. Its present hardware platform is a cluster of multi-disk workstations, connected using an ATM switch. Mitra supports the display of a mix of media types. To reduce the cost of storage, it supports a hierarchical organization of storage devices and stages the frequently accessed objects on the magnetic disks. For the number of displays to scale as a function of additional disks, Mitra employs staggered striping. It implements three strategies to maximize the number of simultaneous displays supported by each disk. First, the EVEREST file system allows different files (corresponding to objects of different media types) to be retrieved at different block size granularities. Second, the FIXB algorithm recognizes the different zones of a disk and guarantees a continuous display while harnessing the average disk transfer rate. Third, Mitra implements the Grouped Sweeping Scheme (GSS) to minimize the impact of disk seeks on the available disk bandwidth. In addition to reporting on implementation details of Mitra, we present performance results that demonstrate the scalability characteristics of the system. We compare the obtained results with theoretical expectations based on the bandwidth of participating disks. Mitra attains between 65% to 100% of the theoretical expectations.
