Applications where the REPRESENTATION of objects needs to be queried or otherwise manipulated need to EXPLICITLY REPRESENT THE REPRESENTATION of objects; we call the representation of the representation of application objects METAMODELING. Some methodologies recognize the existence of meta-level information and the need for representing it (see e.g. OMT). However, it is not handled in a systematic way, and the relationship between models and meta-models isn't clearly defined. In the OO programming language camp, interest in meta-modeling focused on reflection from a language semantics and design point of view. There has been a recent cry in the OO community for multi-paradigm representation of domain knowledge, with the realization that there are business rules that cannot be easily expressed within the object notation (see e.g. [Hoydalsvik et al., 1993] and the 1994 OOPSLA workshop on AI and OO); we believe that meta-modeling can go a long way towards expressing domain rules and constraints. GOALS AND FOCUS: The purpose of this workshop is to explore metamodeling concepts in the context of object-oriented software development, with an emphasis towards: 1. Exploring the additional modeling constructs that are needed-- if any-- to model information at several levels of abstraction, 2. Exploring changes to modeling procedures/heuristics that are needed-- if any-- to build object meta-models and integrating them with object models, 3. Exploring the effects of such changes on design and implementation (e.g. reflective languages, metaprogramming, etc). The desired outcome of the workshop is: 1) a recognition of the need for metamodeling as a way of representing business rules, and a clear definition of its scope, 2) a cross-fertilization of formal and heuristic/informal approaches towards addressing the most pressing issues, and 3) an outline of open practical and theoretical questions that participants feel would advance the theory and practice of metamodeling. REQUIREMENTS FOR ATTENDANCE: Participants are requested to submit 2 to 4 page position papers (1000 - 2000 words) that report on either: 1) theoretical work addressing metamodeling issues, or 2) experience reports on modeling efforts that highlight the need for a metamodeling discipline, or that report on the use of one. Position papers are due by August 15th, 1995. Acceptance notifications will be sent by September 1rst. A representative subset of accepted contributions will be scheduled for presentation during the workshop.

Parallel variants of the relational operators are described. Optimization techniques are then briefly outlined. Attention then turns to commercial systems available today. The tutorial highlights the strengths of each of these systems: Teradata, Tandem, Oracle, Informix, Sybase, and DB2/2. About the Instructor Jim Gray is a specialist in database, transaction processing, and dependable computer systems. He has written many articles and built several systems that embody his ideas on these topics. He is currently a McKay Fellow at UC Berkeley. He has worked at Digital on Rdb and Sorting, worked at Tandem on NonStop SQL, and at IBM on System R, SQL/DS, DB2, and IMS-Fast Path. He is co-author of Transaction Processing Concepts and Techniques, and Editor of the Handbook for Database and Transaction Processing Systems Performance. He is a Fellow of the ACM and is active in the National Research Council. Tutorial B MO 11 09, 14:00 - 17:30 Spatial Database Systems Ralf Hartmut Gueting (University of Hagen) Abstract The purpose of a spatial database system is the management of data about some space in two or more dimensions. Space of interest may be the physical world around us as in geography, urban planning, meteorology, or astronomy. Other spaces may, for example, represent parts of the human body, a VLSI design, or a 3D molecular structure. A spatial database keeps information about objects in such spaces with a clear identity, position, and extent, in contrast to image databases where the focus is on the manipulation of raster images of such spaces. Spatial data management imposes a number of requirements on database systems. Concepts are needed to describe the shape and position of objects in space as well as relationships between them. Data modeling must also provide concepts for the representation of spatially related collections of objects, such as partitions (of a region), or networks. To access efficiently objects in some particular region of the space, specialized spatial access methods are needed. The user interface must support graphical representation as well as overlay of different query results. Since extensions at all levels of the system architecture are needed, extensible database systems are the prime architectural framework for the implementation of spatial database systems. The tutorial aims at giving a coherent picture of the main research results obtained so far in the areas of modeling, querying, data structures and algorithms for system implementation, and system architecture. About the Instructor Ralf Hartmut Gueting is currently a full professor in computer science at the University of Hagen, Germany. He received his Diplom and Dr.rer.nat. degrees from the University of Dortmund. After a one-year stay at the IBM Almaden Research Center in 1985, extensible and spatial database systems became his major research interests. His group has built a prototype of an extensible spatial DBMS, the Gral-System. He is the author of a (German) text book on data structures and algorithms and has published about 35 articles in computational geometry and database systems. He recently was a guest editor of a special issue of the VLDB Journal on Spatial Database Systems. Tutorial C TU 12 09, 14:00 - 17:30 The Evolution of User Interface Tools for Database Applications Ravi Krishnamurthy (Hewlett-Packard Labs) and Moshe Zloof (Hewlett-Packard Labs) Abstract Traditionally, the user interface tools for database applications have lagged the technological advances in GUI revolution. Recent entrants such as PowerBuilder, SQL Windows, NextStep, etc., have made major strides in closing this gap. In order to extrapolate the trends, we introspect the past and forecast the future. We will first give a historical account of the evolution of database UI tools since the early seventies in the context of many facets of database applications (e.g., querying, forms & reports, 4GL capabilities, and end user graphical tools). These tools were aimed at improving the productivity of application developers, the primary clientele of SQL. The advent of PC database management system saw the metamorphism of this clientele to less sophisticated users. These non-programmers (i.e., power users) who wish to build their own applications required different kinds of tools and the PC database industry lead this thrust. We address the design factors in both these types of tools and contrast them. In doing this, we will use examples from some of the current products (e.g., Microsoft's Access, Gupta's SQL Widows, Powersoft's PowerBuilder, etc.) to highlight their power, functionality, levels of abstraction and ease of use. Lastly, we extrapolate on how this UI technology will be evolving in the future. About the Instructors Ravi Krishnamurthy is a senior researcher at H.P. Labs, currently heading the Picture Programming project that is developing the IC-BY-EXAMPLE language. He received his doctorate degree at the Univ. of Texas at Austin and then joined Moshe Zloof at IBM T.J. Watson Res. Center to work on the Office-By-Example project in 1981. In 1985, he joined MCC to work on Budda and LDL, where he subsequently assumed the chief architect position of the joint project. After leaving MCC, he was a co-founder of a start-up company, Logica Information Machines, in which he is still involved as its Chairman of the Board of Directors. Moshe Zloof, principal architect of H.P. Labs, is considered a poineer researcher in the area of data base languages and user interfaces. Back in the 1970's, in a complete departure from the traditional approach and while working at IBM, Moshe created QUERY-BY-EXAMPLE (QBE), the first visual programming language which not only set the stage for considerable research agenda, but also has been incorporated in many successful products such as PARADOX, DBASE IV, ACCESS, and many more. At Hewlett-Packard, Moshe is currently involved in developing the IC-BY-EXAMPLE language - a new paradigm to enable non-programmer professionals to construct their own applications. Tutorial D WE 13 09, 9:00 - 12:30 OQL: Language, Compatibility with SQL, Implementation Sophie Cluet, INRIA Abstract OQL is the standard for object database query languages proposed by the ODMG. It borrows SQL syntax but has a functional nature that makes it simpler to use, implement, and document. Improving its compatibility with SQL(92) and clarifying its relationship with SQL(3) will strongly help its general acceptance by the database community. More important, ANSI(X3H2) and ODMG are working on a proposal for a common standard involving the current OQL. The tutorial addresses a public of both, industrials and researchers. Although standards are clearly of primary interest to industrials, their evolution also provides challenging issues that should not be overlooked by researchers. The tutorial consists of three parts. First, we present OQL(1.2) in details and explain how to construct simple and complex OQL queries. Next, we discuss the OQL vs. SQL approaches and study different possibilities by which OQL can reach full compatibility with SQL. Finally, we briefly consider the language implementation. About the Instructor Sophie Cluet is currently a researcher in the Verso team at INRIA-Rocquencourt. She holds a PhD from the University of Paris-Sud. She is one of the designers of OQL and has implemented for O2 Technology the language's first interpreter and optimizer. She is still very much involved in this area (working on a future release of OQL and new OO optimization techniques). Tutorial E WE 13 09, 14:00 - 17:30 Transformation-based Database Engineering Jean-Luc Hainaut (University of Namur) Abstract Transformation-based software engineering has long been considered as a major scientific approach to build reliable and efficient programs. According to this approach, abstract specifications can be converted into correct, compilable and efficient programs by application of selected, correctness-preserving operators called transformations. In the database engineering realm, transformations that are proved to preserve the correctness of the origin specifications have been proposed in virtually all the activities related to data engineering : schema normalization, DBMS schema development, schema optimization, model translation, schema integration, view derivation, proving schema equivalence, data conversion, reverse engineering, and others. The tutorial is a contribution to the systematic study of both fundamental and practical aspects of database schema transformations. It introduces the fundamentals of database transformations, then it develops a practical toolset of neutral techniques. These techniques are used to revisit the main database engineering processes. The description of a transformation-based CASE tool and the presentation of a reengineering case study demonstrates the applicability of this general approach. About the Instructor Jean-Luc Hainaut is a professor in Information Systems and Databases at the Institute of Informatics of the University of Namur, Belgium. His research interests comprise database technology, database methodology, reverse engineering, information system evolution and CASE technology. Currently, he is heading the multinational DB-MAIN project the purpose of which is to develop general methodologies and CASE tools to assist practitioners in solving database application maintenance and evolution problems. He is the author of two books in database and DSS design, and of over 20 recent conference papers, most of them dealing with transformation techniques. He has presented several tutorials (including three on database reverse engineering and reengineering) in major international conferences on Databases and Information Systems. Tutorial F TH 14 09, 9:00 - 12:30 Repository Internals Philip A. Bernstein (Microsoft Corporation) Abstract A repository is a metadata manager that supports design tools for CASE, CAD and the like. It runs as an application on a DBMS and provides three main functions beyond those of a standard DBMS: relationships, version and configuration management, and extensibility. We explain how these functions can be used by design tools, and what technical requirements are implied by those usage patterns. We then delve into the technical capabilities of each function. For example, relationships are object-valued properties that have special update semantics and can be scoped by configurations. Version and configuration functions allow tools to run either on repository objects directly or on files. Configurations support transitive containment (unlike file systems) and can scope name spaces. A tool vendor can extend the repository's model by adding behavior to standard repository methods on repository objects, e.g., by adding state to the object, checking constraints on the object, and adding methods to the objects. The presentation will draw from examples of Microsoft's and others' CASE tools, and where appropriate will be couched in the OLE object model. About the Instructor Philip Bernstein is a repository architect at Microsoft, where he leads a joint design effort with Texas Instruments to design an open repository for CASE. He was formerly an architect at Digital Equipment Corp., a professor at Harvard University and Wang Institute of Graduate Studies, and VP Software at Sequoia Systems. Dr. Bernstein has published over 70 articles on the theory and implementation of database systems, is coauthor of "Concurrency Control and Recovery in Database Systems" (Addison-Wesley, 1987). In 1994, he was awarded the ACM SIGMOD Innovations Award for "contributions to the development and use of database systems." Tutorial G TH 14 09, 14:00 - 17:30 Temporal Databases Christian S. Jensen (Aalborg University) and Richard T. Snodgrass (University of Arizona) Abstract Temporal database technology has reached a level of maturity and sophistication that clearly illustrates that the support for temporal data management provided by current database products is very far from what is achievable. The tutorial provides an overview of important issues and concepts within temporal database management. It reviews fundamental data modeling concepts and surveys the implementation of temporal database systems. It also features the consensual temporal query language TSQL2 that has recently been designed by an international committee of database researchers and practitioners. TSQL2 adds temporal support to the current SQL standard and is the most complete temporal query language to date. The tutorial is relevant for practitioners who work with databases containing time-varying data, and for database researchers who are interested in temporal data management. About the Instructors Christian S. Jensen is currently an Associate Professor at Aalborg University, Denmark. He has spent 4 years at the University of Maryland and the University of Arizona. Recently, he coordinated and headed two editorial boards for the ongoing consensus temporal database glossary initiative; he is editor for the temporal database benchmark initiative; and he was a member of the TSQL2 Language Design Committee. Richard T. Snodgrass received his Ph.D. from Carnegie Mellon University in 1982 and joined the University of Arizona in 1989. He has written or co-edited three books, including "Temporal Databases: Theory, Design and Implementation.'" He chaired the TSQL2 Language Design Committee, and is now working closely with the ANSI and ISO SQL3 committees to add temporal support to that language. ********** PANELS ********** Panel I TU 12 09, 16:00 - 17:30 Scientific Journals: Extinction or Explosion?

Ceri, Politecnico di Milano, Italy Title : Design of Active Rule Applications: Issues and Approaches Abstract: Rules in database systems can be used to establish and enforce data management policies. A large amount of the semantics that normally needs to be coded by means of application programs can be abstracted and assigned to both deductive and active rules. This trend in designing database applications (called ``knowledge independence'') brings the nice consequence that data management policies can effectively evolve just by modifying rules instead of application programs. The use of rules in modern database systems is a fundamental issue of the IDEA Esprit Project, where it is combined with object orientation. In particular, it inspires the IDEA Methodology, a comprehensive and systematic approach to the design of database applications which use both deductive and active rules. The IDEA Methodology reconciles deductive and active rules by assigning them the role of expressing knowledge about the application domain, either with a purely declarative style, or with a more procedural style. Although active rules are inherently procedural, in many cases they can be automatically or semi-automatically generated from declarative specifications. This invited paper is focused on active rules, the main research interest of the Politecnico in the IDEA project. We concentrate on active rule analysis, design, and prototyping as developed in the context of the IDEA Methodology. Given that active rules are quite complex to understand and manage, we present several abstractions and techniques which enable their safe specification, in particular with respect to collective desired properties (such as termination and confluence). We also informally introduce the notion of modularization, that enables the partitioning of complex rule sets into modules which exhibit nice interaction properties. Biography: Stefano Ceri is full professor of Database Systems at the Politecnico di Milano, and visiting professor at Stanford University. His research interests are focused on extending database technology to incorporate data distribution, rules, and object-orientation. He is author of several international books and articles, including books on distributed databases (McGraw-Hill, 1984), deductive databases (Springer-Verlag, 1990), conceptual database design (Benjamin-Cummings, 1992); he is co-editor with Jennifer Widom of a recent book on active databases (Morgan-Kaufmann, 1995). He was general chairman of the first International Conference "Extending database Technology" and he is member of the EDBT Foundation, VLDB Endowment, and DOOD Steering Committee. Speaker : Professor M. Kifer, University of New York at Stony Brook, U.S.A. Title : Deductive and Object Data Languages: A Quest for Integration Abstract: Early hybrids of object-oriented and deductive languages were just rejects from secret AI labs. However, by mid-80's, workers in databases and logic programming began to take notice. The temptation was hard to resist: the object-oriented paradigm has a better way of specifying and manipulating structured objects, while logic and deduction offer the power and flexibility of ad hoc querying and reasoning. Thus, hybrid languages have the potential for becoming an ideal turf for cultivating the next generation of information systems. The approaches to integration of the two paradigms range from logic-based languages with unified declarative semantics to message-passing prologs to rule-based yet deductively-challenged stews to Prolog/C++ brews. In the past eight years, my colleagues and I have been plowing our way through the fields towards an object-based logic that would be capable of capturing most of the essentials of the object-oriented paradigm. The overall plot here is that once the fundamentals are in place, the actual hybrid programming languages can be carved out of the logic the same way as deductive data languages are carved out of the classical logic. There are two distinct aspects to object-orientation: structural (the statics) and procedural (the dynamics). Most of the static aspects are relatively easy to capture in logic, as seen from our work on F-logic. The dynamics were harder to tame, as there was no widely accepted solution to the problem of state changes in deductive languages, even for languages based on classical logic. Our recent work on Transaction Logic appears to provide an adequate framework for specifying the dynamics in classical deductive languages. In this talk, I will review F-logic and Transaction logic, and show that the two can be combined in a natural way, yielding a unified foundation for future work on deductive object-oriented languages, both in theory and practice. At the end, I will discuss a number of areas that could still make use of the plow.

Sarda, India Abstract: The context of time is basic to all real-world activities; however, the conventional database management systems provide little support for modelling of time and management of history data. The research in temporal databases over the past decade has contributed many concepts and techniques to support temporal data management. The objective of this tutorial is to provide an overview of temporal data models, query languages, implementation strategies, and applications for real-life problems. The tutorial also aims at providing a pre-view of some of the on-going research efforts to further enhance facilities of temporal databases. Specifically, the following topics will be dealt with in the tutorial: - temporal domain and its representation - extensions to relational model - grouped and ungrouped models - relational temporal algebra - TSQL-92 (SQL-92 extended with temporal facilities) - examples and a case study - spatio-temporal and interval data type extensions - branching time and alternatives in future time - temporal extensions to object -oriented data models - schema evolution - storage techniques for temporal databases - transaction management for temporal databases The tutorial will be of interest to database users, practioners, implementors and researchers as it covers modelling, case-studies/examples, techniques and future directions. Biography: Nandlal L. Sarda is a Professor at (and presently Chairman of) the Department of Computer Science and Engineering at Indian Institute of Technology, Bombay. He has been teaching, researching, practicing and consulting in the area of database management systems for the last 20 years (mostly at Bombay except for two years in Canada). He has taken active part in the coordinated activities of the temporal database research community, and has contributed many journal and conference papers in this area. His other research interests include distributed and object oriented database systems. He has been associated with many international conferences in the database area, and would be serving as one of the PC Chairs for the VLDB'96 to be organized in Bombay. Tutorial 2: "User Interfaces for Desk-Top Object Oriented Databases" - Professor M. Livny, USA Abstract: Until recently, user interface have been considered by the database community as second class citizens. For many years, most of the energy of the community has been devoted to the functionality and performance aspects of database management systems. Database design and query formulation were viewed as tasks performed by professionals who use cryptic DDLs and 4GLs. The end-user was expected to submit canned queries via a form driven terminal to a database designed, created and maintained by a professional DBA. The main focus of the community was very-large multi-user high-performance databases. Like many other aspects of computing, database management systems have recently experienced a demand for intuitive user interfaces that can be used by non-experts. As database technology has been moving from the machine room to the desk-top, the distinction between the DBA and the end-user has disappeared. More and more end-users with very little database expertise would like to build a database for a relatively small collections of dynamic and complex data to be shared by a small group of users. A typical example for such an environment are scientific experimental studies where half a dozen scientists share several hundreds of Mega-Bytes of data that consist of objects with hundreds of attributes. The abstraction and data encapsulation capabilities of OO databases make it much easier to capture the schema of complex data. Unfortunately, most systems expose these capabilities to the end user only via cryptic interfaces. While OO technology has the potential of making the task of managing Desk-Top databases much easier to the non-expert, the lack of intuitive user interfaces prevents most users from exploiting this potential. OO databases can become a much more effective desk-top tool if they will provide easy access to their entire range of capabilities. Graphics has proven to be a very effective means of providing an intuitive interface to complex systems. Building a graphical user interface to a database, however, is a complex and time consuming process. Designing, implementing, and testing such an interface requires expertise in a wide range of disciplines. The tutorial will target researchers and practitioners who would like to develop such interfaces to OO databases in order to make these databases broadly accessible to non-experts. A basic knowledge of OO and database concepts and terminology will be assumed. The audience will be presented with a methodology for designing, implementing, and testing graphical user interfaces for OO databases. A formal framework that captures the interaction between the visual presentation of the data and the database management system provides a foundation to the framework. It is based on three models - Data, Personal, and Visual - and metaphors that provide mapping between the models. An overview and evaluation of existing graphical interfaces will be provided. The different implementations will be classified and compared. Special attention will be devoted to a graphical schema management system that was designed for an OO Experiment Management System. Experience obtain from testing the interface in real-life experimental studies will be reported.

Over the past three years, the ESPRIT basic research programme has funded the NATURE project in order to address fundamental issues associated with the theory of knowledge representation and management, domain modeling and reuse, process guidance and traceability within requirements engineering. The workshop is intended to promote discussion of the main project results through presentations, software demonstrations, and a panel discussion. Participation/Registration: --------------------------- The workshop is held on the day prior to the European Software Engineering Conference in Sitges, Spain (see the WWW page http://www-fib.upc.es/Congressos/ESEC95/fulltext.txt for registration and accomodation information). The workshop is open for participants from industry as well as research with an interest in requirements engineering. For registered participants in ESEC 95, there is no extra registration fee. When you register for ESEC, please mention that you intend to participate in the workshop, and send a brief notification message to doemges@informatik.rwth-aachen.de. Technical Overview: ------------------- A general framework developed in NATURE for thinking about requirements engineering defines RE as a process of establishing a system vision in context. The RE process is viewed in the three dimensions of technical representation, depth of specification, and social agreement. Technical project contributions based on this framework include: - knowledge representation and reasoning mechanisms and tools which achieve representational freedoms through + different kind of representations ranging from informal hypertext to semi-formal graphics to formal conceptual models + meta-model based interaction between different perspectives, including reverse modeling and view integration of existing software, goal and business models + similarity analysis based on qualitative and quantitative models - models and tools for supporting the reuse of generic domain knowledge during requirements capture and requirements critiquing based on a set of domain models which have been both formally specified and empirically validated - architectures for RE environments which support model-guided and (almost) automatic requirements traceability along all three dimensions through a combination of process repositories and process-integrated tools - process guidance according to a flexible process modeling approach that interprets RE as a process of contextual decision-making and includes traditional plan-based workflows as well as automatable parts of the process as special cases.

Among other things, this revision implements the NSF Investigator Financial Disclosure Policy. Other sections have been revised, as appropriate, for clarity as well as to make the Guide consistent with current NSF policies, practices and procedures. A complete list of significant changes is included in the GPG. The GPG will be effective for all proposals submitted on or after October 01, 1995. Proposals submitted prior to October 01, may continue to use the forms contained in the previous edition or the forms contained in the new GPG (95-27 or 95-28). After October 01, 1995, the previous version of the GPG should be discarded. The ascii version of the GPG is now available on STIS as nsf9527.txt and the Proposal Forms Kit is available as nsf9528.txt. The Proposal Forms Kit containing forms formatted in Microsoft Word for Windows 6.0. also is available as nsf9528.doc. These electronic versions may be used in submission of proposals to NSF. In the near future, the GPG text also will be available in both Microsoft Word and html formats. A separate notice will be sent when available. In addition, paper copies of the revised GPG will be sent to NSF staff and the Authorized Organizational Representative at current NSF grantees by early September. Any questions regarding the revised version of the GPG should be referred to the Policy Office at policy@nsf.gov or by phone on 703-306-1243.
