(Sponsored by Computer Society of India)


The Eighth International Conference on Management of Data (COMAD '97) is scheduled to be held at Hotel Park Sheraton, Chennai (Madras) between 18th and 20th of December 1997. COMAD '97 is being sponsored by The Computer Society of India (CSI). The conference is now recognized as the annual meeting point of database researchers and database professionals of all hues. The conference also offers a unique opportunity for the attendees to meet world renowned experts in database and allied areas like Client server computing, Object technology and Application development.

The purpose of this conference is to provide a forum for researchers, users, system builders, and database consultants to discuss issues of common interest, to deliberate on common and usual challenges, to propose innovative solutions, to share interesting experiences and to foster cross fertilization of ideas from different academic disciplines and application environments. The conference will strive to present through its technical sessions - contributed and invited papers, tutorials and panels - a healthy blend of theoretical advancements in the field and practical innovations and developments.

Today, database support is central to almost all applications. The acceptance of the technology is also widespread. Therefore, anyone who is involved in strategic planing, analysis and design, development, implementation and management of large industrial grade applications will immensely benefit from attending this conference.

Thus researchers, students and faculty, trainers, application specialists, system managers, technology watchers and marketing executives of RDBMS/Client Server/CASE products will all find sources of valuable information at COMAD '97.

The central focus, however, will be its rich technical sessions of contributed papers, projecting a wide spectrum of research results from all over the globe.


Developing Business Object Applications
Dr Dilip Patel Dr Yuan Sun Dr Saba Zamir

Many leading information technology practitioners advocate that the success of information systems in organizations lies in the conceptual and clear understanding of the business, an acceptance that business is in a constant state of flux and that there is a need to shift from an application view to a business view. This tutorial outlines the inadequacies of building business information systems based on business requirements that are only a snapshot of a business's dynamic life. It also assesses the concept of Business Objects as a means of building information systems that meet the needs of the business. The tutorial will concentrate on the specification, design and implementation of business object components and assess their suitability for the delivery of business application. The tutorial will be based on the work of Object Management Group's, Business Object Domain Task Force, Oliver Sims work on Co-operative Business Objects and the research work undertaken at South Bank University.

Data Warehousing and OLAP for Decision Support: Foundations and Techniques
Dr Laks V S Lakshmanan

Traditional (especially, relational) database technology is best suited for robust and efficient Online Transaction Processing (OLTP) on operational data. Decision support applications require efficient support for complex analyses and pattern mining on historical data. The technologies of Online Analytical Processing (OLAP) and Data Mining are evolving in this direction. Both technologies often require historical data to be available in a separate dedicated Data Warehouse, where data from multiple heterogenous sources are assimilated, their numerous conflicts reconciled, and integrated. Some of the major steps involved in this process are (i) interoperating with heterogenous data sources, and (ii) supporting OLAP breed of "queries" and their efficient processing. In this tutorial we will discuss the state of the art, limitations of the technologies as they exist today, as well as research that has gone into laying the foundations for heterogenous database interoperability, multi-dimensional OLAP style analysis queries and their efficient processing, key ingredients for realizing an effective Data Warehousing/OLAP technology. This tutorial will cover pragmatic issues as well as foundations and techniques.

About the Speaker:

Laks V S Lakshmanan is an Associate Professor in the Department of Computer Science, Concordia University, Montreal, Canada, where he is heading the Database Systems Research Group. He graduated from the Indian Institute of Science, Bangalore, India, and spent two years at the University of Toronto as a post-doctoral fellow. His research covers numerous aspects of relational, object-oriented and deductive databases, including multi-database interoperability, integration of heterogenous data sources (incl. semi-structured and unstructured ones such as the internet, spreadsheets, documents, etc.), multi-dimensional databases, data warehousing, OLAP, and data mining. This tutorial is based on a tutorial on a similar topic to be given by Laks Lakshmanan and Raymond Ng at the International Conference on Information and Knowledge Management, Las Vegas, CA, USA, November 1997, and a mini-course on the same topic given by Lakshmanan at the Indian Institute of Science, Bangalore, during March-April 1997.

Data Mining

Mr K Padmanabhan, Dr K Sundar, Dr Santosh Mohanty, Mr Deenanath Kholkar

With efficient construction and verification of models of patterns embedded in large databases, data mining is emerging as a key technology for enterprises that wish to improve quality of their decision making and gain competitive advantage by exploiting operational and other available data. Data Mining evolved as a collection of applicative problems and efficient solution algorithms relative to rather peculiar problems, all focussed on the discovery of relevant information hidden in databases of huge dimensions. These tools and techniques are the subject of the rapidly emerging field of knowledge discovery in databases.


Research Issues in Temporal Databases
Professor N.L. Sarda

The real-world events and activities have the context of time, and entities change their state over time. Many applications require this time dimension to be explicitly captured within the database design as well as within the processing, so that time-validity of data can be examined and history data can be analyzed. Conventional database systems offer little support for this beyond providing 'date' and 'time' domains and leaving it to users to meet the requirements through design and programming. Realizing that this is quite inadequate, there has been considerable research effort directed towards extending database systems' functionality for supporting time and history data. In this talk, the major achievements of this research in temporal databases, the impact they would have on future DBMSs, and how application designers should exploit these functionalities will be highlighted.

Security, Fault Tolerance, and Information Warfare
Professor Sushil Jajodia
Information warfare has received a great deal of attention in the press lately; however, most of the focus has been on how an attacker disrupts an organization's operations. This talk will discuss issues and methods for survivability of systems under malicious attacks. To protect from information attacks, it is necessary to take steps to prevent attacks from succeeding. At the same time, it is important to recognize that not all attacks can be averted at the outset; attacks that are successful to some degree must be recognized as unavoidable, and comprehensive support for identifying and responding to attacks is required. This places increased emphasis on the ability to live through and recover from successful attacks.

Although recovery methods have been studied extensively by researchers in fault tolerance and in database areas, the existing methods assume that failures are independent of each other. This assumption does not hold under information attacks because these attacks are likely to be coordinated and malicious in nature and, moreover, the attacker can be assumed to be familiar with the intricacies of the system being attacked. Therefore, achieving recovery requires modifications and extensions of existing techniques together with novel techniques that are only suitable for surviving information attacks.

We have adopted a fault-tolerance approach that addresses all phases of survivability: attack detection, damage confinement, damage assessment and repair, and attack avoidance. This talk will describe our research dealing with each of these phases.
