Does anyone recognize the following abstract and section titles? Judging from the citations, the original probably dates from 1991 or 1992. thanks, Maurice Herlihy ABSTRACT This paper explores atomic commitment among heterogeneous distributed databases. Two cases are considered, one where the individual databases participating in the system do not externalize their commit protocols, and a second, where the participating databases do externalize their commit protocols. With regard to the latter case I am proposing new heterogeneous commit protocols, one for joining databases that have different 2-phase commit protocols, and one for uniting databases which employ a 3-phase protocol with others employing a 2-phase commit protocol.

Yet driving (or surfing where the highway is flooded) can be a frustrating experience---finding your way can be difficult, road safety is poor, and when you arrive it may not be where you wanted to be. The Internet and World Wide Web have been designed essentially bottom-up to perform simple tasks, with a heavy emphasis on retrieval rather than modification of information, and on individual rather than cooperative creation and use of information. Moreover, openness of interchange has been the immediate goal, rather than restricted access to, and commercial management of, the information. The thesis of this paper is that major improvements in areas such as updatability, version management, and security are now urgently needed, and can be made by a combination of applying conventional database technology, and of extending this technology appropriately for the novel aspects of the environment. Beyond the elementary considerations for manipulating and managing shared information lies the need to raise the level of semantic awareness of the underlying systems. This is true both at the meta-level, where the description of available information may not be immediately intelligible to a given individual user, and at the level of the content of the information itself. What existing treatments of data semantics are applicable to the information superhighway, in handling the meta-information and the information content? What new approaches hold promise when focused on this area? The range of media to be considered includes text, image, audio, and video, together with hypermedia combinations of these. What information can be discovered in a generalized "document", and what did its authors explicitly aim to convey? Is there a general theory of signs that can usefully be applied, for example to inflexions in audio, or to gestures in video? The author will offer some speculative answers, and will look to the audience to improve upon them---and to raise new questions. --------------------------------------------------------------------------- THURSDAY Information Visualization: The Need for a Data Base Approach Jim Foley Georgia Tech My basic thesis is that the data base comunity and the information visualization community need to work together to realize the full potential of information visualization. Information visualization, like its cousin scientific data visualization, is a powerful way to effectively convey information to the user. Unfortunately, much of the information that we would like to visualize is not well-structured or well-described: notions of schemas, views, and semantic descriptors are generally lacking in information systems, such as the World-Wide Web, which we would like to visualize. This means that those who seek to create information visualizations must have considerable domain and data knowledge and may have to restructure information manually, making the creation of visualizations a labor-intensive process. We need ultimately to move toward a situation where visualizations can be created automatically, which means integrating data base concepts with visualization tools. This will in turn: + support the creation of navigational overviews of information spaces such as the World-Wide Web + allow users to make task-oriented queries of information systems + provide for automatic adaptation of information presentations to accomodate different screen sizes, different network bandwidths to the user, various user skills, and user disabilities. + allow multiple graphical views of information easily to be created. This presentation will challenge the data base community to broaden their venue to include the very important issues at the interface between data bases and information visualization. I will do this by discussing two visualization projects at Tech, showing how they need data descriptors to be effective. The first example is automatic generation of dialogue boxes from a semantic data model. A rule-driven generation approach is used, driven by meta-information in the semantic data model. Sun's Open Look style guide rules for dialogue boxes were encoded in a machine-processable form, and used to select approriate widgets for dialogue boxes. Semantic dependencies between widgets, also encoded in the data model, were used to determine the top-to-bottom placement order of the widgets. The second example is visualizing the World-Wide Web. We have developed a series of visualizations of the Web to show relationships between web pages. The visualizations are part of a navigational tool which uses queries, abstraction, and visual bindings to reduce the visual clutter which occurs when many pages and links are shown. Not surprisingly, much better results are obtained if the links and nodes are semantically typed. We will suggest that semantic data models should form the basis of next-generation authoring systems for the WWW. --------------------------------------------------------------------------- FRIDAY Value-added Mediation in Large-Scale Information Systems Gio Wiederhold Stanford University ABSTRACT: Many information-processing tasks can be defined independently of the source databases and of the applications. On networks, they can be performed by independent entrepreneurs. Such mediating services must be of value to the customers, so that their applications will access mediators rather than sources directly. Several types of value can be considered: improvement in access and coverage, improvement of content, and delegation of maintenance. We have defined mediators as modules performing such services, and will define some of the criteria for mediating modules: ownership by party who assumes responsibility for the results of the services, domain-specificity to delimit the scope of such a responsibility, and, of course, conformance with interface standards that enable interoperation. Application that benefit from mediation include planning and other decision-making tasks require information from diverse resources, as databases, reference systems, data obtained from sensors, and analyses projecting trends into the future. The sources are often autonomous, some of them are public, and will be heterogenous. The heterogeneities include representation, scope, level of abstraction, and context. Mediated results are intented to be composable by higher level applications, which have to solve problems involving multiple subtasks. Mediators hence need a machine-friendly interface to support those applications. This interface must provide good communication, while encapsulating the domain-specific tasks, so that the complexity of the composed system is not much greater than that of the individual subtasks. However, questions of effectiveness and efficiency do arise, and must be dealt with by exploiting the processing and storage capabilities of modern hardware. The corresponding architecture is a generalization of a server-client model. The partitioning enhances maintainability: the applications software staff can concentrate on functional improvements, the data resource managers on operational issues, and the technical maintenance is concenentrated in the mediator layer. The concept is network oriented, and it is hoped that mediationg services will be provided over the network by domain specialists. A number of projects are now using the mediator concept, and some standards, as KQML, are being promulgated for the interfaces that are required. We will describe, a.o., a prototype effort to support the U.S. Air Force concept of an Integrated Weapons Systems Database. ===================================================================== REGISTRATION INFORMATION ===================================================================== REGISTRATION FORM =================== (IFIP DS-6 Working Conference, May 30 - June 2, Atlanta, Georgia, U.S.A.) ##################################################################### ################### REGISTER BEFORE APRIL 30 !! ##################### ##################################################################### Name: _________________________________ Social Security Number: ______________ Exact name you would like on your name tag ___________________________________ Position: __________________ Organization: ___________________________________ Address: ________________________________________ ________________________________________ ________________________________________ Business/home phone # _______________________ Fax # ________________________ Conference Fee $350 Payment Enclosed $________ (U.S. Funds) ______ Check enclosed (Make check payable to Georgia Tech) Charge with: ______ American Express ________ VISA _______ MasterCard _______ Discover Card No: ______________________________ Expiration date ________ Cardholder's Name ___________________________________ Signature __________________________________ HOTEL RESERVATION FORM ====================== Single Rooms required _______(enter number) $115 per day Double Occupancy rooms ______(enter number) $95 per person per day (Note: spouses and accompanying members of family will receive breakfast and lunch in the above room rate.)
