        	FINAL PROGRAM FOR THE JOINT CONFERENCE

      1995 ACM SIGMOD International Conference on Management of Data
				&
        Fourteenth ACM SIGACT-SIGMOD-SIGART Symposium on Principles
			of Database Systems (PODS)

			The Fairmont Hotel
		       San Jose, California
			 May 22--25, 1995

                       Letter from the Chairs
============================================================================

The ACM SIGMOD/PODS 95 Joint Conference continues the tradition of the
last few years in bringing together the theoretical and applied
database communities.  The joint conference will feature the
presentation of original research papers, invited talks, tutorials,
industrial sessions, panels, and demonstrations of experimental
database prototypes.

The SIGMOD and PODS conferences will overlap for two days, but each
conference will have a separate third day without overlap.  There will
be, however, only one registration process for the joint, four-day
conference.  Attendees will receive both proceedings and be encouraged
to attend sessions in both conferences.  The award session, reception,
lunch and the banquet are joint events.

We are holding this conference in Silicon Valley, one of the hotbeds
of industrial database activity, and have made a special effort to
take advantage of local database expertise in our invited talks, panels,
tutorials and industrial programs.  We hope you will meet members of
our broad database community who may not ordinarily attend SIGMOD/PODS
and hear about their activities.  As we reach the mid-point of the
decade of the '90's, the world of data spans architectures from mobile
computing through massively parallel systems, and includes an
ever-increasing range of data, from the traditional to multimedia
objects to real time satellite data capture.

The SIGMOD/PODS Joint Conference represents the combined efforts of
the theoretical and applied database communities to tackle the
new challenges facing the database professionals.  We encourage you 
to participate in what promises to be an exciting and important event.

==============================================================================

	Database Metatheory: Asking the Big Queries
	Speaker: Christos Papadimitriou (U.C. San Diego)
	Monday, May 22th, 9:00am

	Abstract:

Is "database theory" an oxymoron?  Or is it a platitude?  What is
the fitness measure that decides the survival of ideas (and areas) in
mathematics, in applied science, and in computer science?  Which ideas
from database theory during the past twenty-five years have influenced
research in other fields of computer science?  How many were
encapsulated in actual products?  Is applicability the only and
ultimate justification of theoretical research in an applied science?
Are diversity, inclusiveness, and exhaustiveness undesirable
attributes?  Are applicability pressures really exogenous and
unwelcome?  Are negative results appropriate goals of theoretical
research in an applied science?  If scientific theories must be
refutable, what are the "hard facts" that provide the possibility of
refutation in the case of database theory?

	The Speaker:

Christos H. Papadimitriou got his PhD from Princeton in 1976; he
has since taught at Harvard, MIT, Stanford, and Athens
Polytechnic. Since 1988 he has been the Jacobs Professor of Computer
and Information Science at the University of California San Diego.  He
has published four books (including "The Theory of Database
Concurrency Control" and "Computational Complexity") and over 200
articles on the theory of algorithms and complexity, and its
applications to optimization, databases, artificial intelligence, and
mathematical economics.

PODS Tutorial 1. Constraint Programming and Database Languages: A Tutorial
Instructor: Paris C. Kanellakis (Brown U.)
Monday, May 22nd, 1:30pm

	Abstract:

Programming with constraints as primitives can lead to powerful extensions of
both deductive and object-oriented data models.  The property that makes this
new database programming paradigm (called Constraint Query Languages or CQLs)
applicable to areas such as spatial databases, where previous data models have
weaknesses, is that its basic data type is spatial point set, i.e., a
generalization of the relational tuple data type that is close to the natural
language specification of the application area.  Most importantly,
I/O-efficient access to sets of such generalized tuples can be supported
through existing multi-dimensional searching data structures.  This
facilitates the design and implementation of languages for applications such
as: solid modeling in design databases, map overlays in geographic databases,
and subsequence matching in scientific databases.

This tutorial is an overview of the development of constraint programming for
database applications.  We examine: (1) the expressive power for various
classes of constraints both linear and nonlinear, (2) calculus/algebra
language designs combining constraints and complex objects, (3) optimization
in the context of constraints, and (4) new data structures for indexing very
large sets of constraints. We survey the features of constraint logic
programming, deductive databases, and object-oriented databases that are
preserved in CQLs and we highlight the challenging new technical problems.

	Instructor:

Paris C. Kanellakis is a Professor of Computer Science at Brown University. 
He received his Ph.D. in computer science from MIT in 1982. He has been 
an Alfred P. Sloan Fellow in Mathematics (87-89) and held an IBM Assoc.
Professorship in Computer Science (89-90).  His primary work and interests are
in the areas of: principles of database systems, constraint programming
languages, logic in computer science, and the theory of concurrency.  He has
published extensively on these topics in computer science journals and
conferences and is author of the chapter "Elements of Relational Database
Theory" for the Handbook of Theoretical Computer Science (Elsevier, 1990).
He has chaired a number of conferences on databases and on constraint
programming, edited collections of papers on these themes, and serves as
editorial board member representing these areas for: Theoretical Computer

PODS Tutorial 2. Research Problems in Genome Databases
Instructor: Dr. Nathan Goodman (Whitehead Institute / MIT Center for
	    Genome Research)
Tuesday, May 23rd, 10:30am

	Abstract:

The Human Genome Project is a fifteen year, international project that
seeks to identify  all of the genes in the human genome, and to eventually
sequence the 3 billion bases of DNA that comprise the human genome.  The
Human Genome Project is a fascinating scientific adventure and raises
exciting research challenges for computer science.  This seminar will
present several kinds of database challenges that arise.

    1.  Laboratory databases have to  keep track of tens to hundreds of
thousands of samples as they flow through complex, multi-step procedures.
To make matters worse, these procedures change frequently as new lab
techniques are introduced, and the database must evolve to keep pace.

    2.  There is a need for databases to keep track of the results produced
by genome labs, which are often complex structures such as maps, and
sequences.

   3.  There is a need for databases that integrate results from multiple labs.

   4.  A great deal of genomic data is descriptive in nature and is best
represented as free text.  There is a need to integrate text databases with
more traditional databases.

    5.  An increasing amount of genomic data is visual in nature, leading
to a need for image databases.

   6.  Scientific results generally consist of (i) data, and (ii) an
interpretation of the data in light of current theory.  In most genome
databases, the data and results are explicit, but the underlying theory is
implicit.  Since theories change from time-to-time, we are left with the
very big problem of reinterpretting old data in a new light.

PODS Tutorial 3. Combinatorial Games in Database Theory
Instructor: Phokion G. Kolaitis (U.C. Santa Cruz)
Wednesday, May 24th, 10:30am

	Abstract:

During the past fifteen years, the study of rule-based
query languages has occupied a prominent place in database theory.
Much of the work in this area has been devoted to
a comprehensive investigation of the expressive power of such
query languages.  In carrying out this investigation, researchers
have relied heavily on the method of combinatorial games, a versatile method
that originated in classical mathematical logic and became quite indispensable
in finite model theory.

The aim of this tutorial is to present the main combinatorial
games used in database theory, give a representative sample
of their numerous applications, but also indicate some of their limitations.
In particular, the tutorial will cover Ehrenfeucht-Fraisse' games,
games for monadic NP, and pebble games. Moreover, it will illustrate
the use of these games in relational calculus, Datalog, and fixpoint logic.

	Instructor:

Phokion G. Kolaitis is a Professor of Computer and Information
Sciences at the University of California, Santa Cruz, U.S.A.
His research interests include finite model theory, computational
complexity, and database theory. In recent years, he has served

Fellowship.

SIGMOD Tutorial 1. Indexing Multimedia Databases
Instructor: Christos Faloutsos (AT&T Bell Labs and U. Maryland)
Tuesday, May 23rd, 8:30am

	Abstract:

The tutorial surveys state-of-the-art methods for storing and retrieving
multimedia data from large databases.  Records (or documents) may consist
of formatted fields, text, images, voice, animation, etc.  A sample query
that we would like to support is "in a collection of 2-d color images, find
images that are similar to a sunset photograph."  The idea is to use feature
extraction functions, which map an image into a point in feature space, so
that we can use spatial access methods (SAMs) to accelerate the search.
The tutorial examines the properties of good feature extraction functions,
highlights subtle problems (e.g., the 'dimensionality curse'), and gives
solutions.  Finally, it presents case studies and prototype systems for 2-d
and 3-d medical image databases, 2-d color image databases, and 1-d time
series databases.

	Instructor:

Christos Faloutsos received the B.Sc. degree in Electrical Engineering
(1981) from the National Technical University of Athens, Greece and the M.Sc.
and Ph.D. degrees in Computer Science from the University of Toronto, Canada.
Since 1985 he has been with the department of Computer Science at University of
Maryland, College Park; he is currently on a leave at AT&T Bell Laboratories.
In 1989 he received a Presidential Young Investigator Award from the National
Science Foundation.  His research interests include physical data base design,
searching methods for text, geographic information systems and indexing methods
for medical and multimedia databases.

SIGMOD Tutorial 2. Storage Technology: RAID and Beyond
Instructor: Garth A. Gibson (Carnegie Mellon U.)
Tuesday, May 23rd, 10:30am

	Abstract:

This tutorial is intended for researchers and practitioners interested
in current trends in storage systems.  It will highlight storage
technology trends including areal density growth, disk diameter shrinkage,
rising rotation rates, embedded controller caching and reordering,
peripheral interface evolution, and drive support for redundant disk
arrays (more commonly called RAID).  It will also highlight the evolution of
RAID technology, expected to be a 13 billion dollar industry by 1997.
RAID coverage will include a brief review of the historical development of
common RAID levels (redundancy organizations and workload optimizations) then
focus on techniques for overcoming write bandwidth bottlenecks and on-line
failure recovery performance.  Finally, recent trends toward
RAID-style support for network-based parallel storage systems will be covered.

	Instructor:

Garth Gibson is an assistant professor in the School of Computer Science
and the Department of Electrical and Computer Engineering at Carnegie 
Mellon University.  He leads the Parallel Data Laboratory's research 
into high-performance, highly-available,  networked, file and storage

Award and was published by the MIT Press in 1992.

SIGMOD Tutorial 3. Workflow Automation: Applications, Technology, and Research
Instructor: Amit Sheth (U. Georgia)
Wednesday, May 24th, 10:30am

	Abstract:

With increasing global exposure, today's enterprises must react quickly
to changes, rapidly develop new services and products, and at the same
time improve productivity and quality and reduce cost.  Business process
re-engineering and workflow automation to coordinate activities throughout
the enterprise are recognized as important emerging technologies to support
these requirements.  Rosy estimates of a multi-billion dollar marketplace
for workflow software has resulted in significant commercial activities
in the area, with over fifty products now claiming to support workflow
automation.  While many help to automate document- and image-driven office
applications, therefore helping to improve the productivity of small groups,
most current products fail to support: (a) mission critical and complex
applications with requirements such as failure handling and recovery, and
(b) interoperability with existing heterogeneous information systems.
In this tutorial, we will discuss requirements for applications involving
workflow automation, present an overview of the current state-of-the-art in
products, and present some of the research efforts that are attempting to
respond to unmet challenges.

	Instructor:

Dr. Amit Sheth directs the Large Scale Distributed Information Systems
(LSDIS) Lab and is an Associate Professor of Computer Science at the
University of Georgia.  Earlier he worked for nine years in the R&D
labs at Bellcore, Unisys, and Honeywell.  He has lead projects on
heterogeneous DDBMS, factory information system, integration of
AI-database systems (BrAID), transactional workflows (PROMT and
METEOR), federated database tools (BERDI and TAILOR), multidatabase
consistency, and data quality (Q-Data).  LSDIS lab maintains very
active collaboration with industry, and has won significant projects
in the areas of interoperable information system and workflow
management (under the Healthcare Information Infrastructure Program
awarded by NIST) and global information system and management of
heterogeneous digital data (awarded in the Massive Digital Data
Systems initiative).  Prof. Sheth has published over 70 papers, given
over 45 invited talks and 13 tutorials, and lead two international
conferences and a workshop as a General/Program (Co-)Chair.  He has
also served twice as an ACM Lecturer, has been on over twenty five
program and organization committees, and is on the editorial board of
four journals.

SIGMOD Tutorial 4. Integration Approaches for CIM
Instructor: Moira C. Norrie (ETH Zurich)
Wednesday May 24th, 2:00pm

	Abstract:

We describe and compare different integration approaches for the exchange
and consistency of product data across Computer-Integrated Manufacturing
(CIM) component systems.  In particular, we present the main features of
current CIM systems and compare these to the various forms of multidatabase
approaches proposed by the database community.  The CIM integration effort
is based on a number of emerging standards.  We provide an overview of
the STEP/EXPRESS standard for the exchange of product data and discuss
the merits and drawbacks of EXPRESS as a global data model.

	Instructor:

Moira Norrie joined the Database Research Group of Prof. Hans-Jorg Schek
at ETH Zurich, Switzerland in January 1993. Her previous posts include
lectureships at the Universities of Glasgow and Edinburgh in Scotland and a

SQL Standard, SQL3, expected to be approved in 1997.  SQL3's new capabilities
can be divided into two categories: extensions to relational facilities
(new data types, new predicates, triggers, recursive query expressions, view
updatability, stored procedures, control flow, exception handling, and a
call-level interface), and object support (abstract data types, encapsulation,
object identity, inheritance, polymorphism, dynamic binding, parameterized
types, and collection types like set, list, and multiset).
