This Volume Contains The Proceedings Of The Second International Conference On Advances In Information Systems (advis) Held In Izmir, Turkey, 23–25 October 2002. This Conference Was Dedicated To The Memory Of Prof. Esen Ozkarahan. He Was A Great Researcher Who Made An Essential Contribution To The Development Of Information Systems. Prof. Ozkarahan Was One Of The Pioneers Of Database Machine Research And Database Systems In Turkey. This Conference Was Organized By The Computer Engineering Department Of Dokuz Eylul University In Izmir. This Department Was Established In 1994 By Prof. Ozkarahan And He Worked There For The Last ?ve Years Of His Life. The Main Goal Of The Conference Was To Bring Together Researchers From All Around The World Working In Di?erent Areas Of Information Systems, To Share New Ideas And Present Their Latest Results. This Time We Received 94 Submissions From 27 Countries. The Program Committee Selected 40 Papers For Presentation At The Conference. During The Conference A Workshop Was Organized On The Topic “new Information Technologies In Education”. The Invited And Accepted Cont- Butions Cover A Large Variety Of Topics: General Aspects Of Information Systems, Databases And Data Warehouses, Information Retrieval, Multiagent Systems And Technologies, Distributed And Parallel Computing, Evolutionary Algorithms And System Programming, And New Information Technologies In Education. The Success Of The Conference Was Dependent Upon The Hard Work Of A Large Number Of People.

Therefore, preserving the aggregation concept in database implementation is essential. In this paper, we propose models for implementation of aggregation in an Object-Relational Database Management System (ORDBMS) through the use of index clusters and nested tables. ORDBMS is a commercial Relational Database Management Systems (RDBMS), like Oracle, which support some object-oriented concepts. We will also show how queries can be performed on index clusters and nested tables. Preserving Aggregation in an Object-Relational DBMS 5 with OID 'HDC1' may belong to harddisk with OID 'HD1' as well as harddisk 'HD2'. Depending on the situation, the above sharable type may not be desirable. We can enforce non-sharable type of aggregation by creating a single primary key for the "part" object, and treat the cluster key as a foreign key rather than part of the primary key. The following Figure 4 shows an implementation of the example in Figure 3 as a non-sharable type (the implementation of the cluster and the cluster index remain the same). ## CREATE TABLE Harddisk ( HDoid VARCHAR2(10) NOT NULL, Capacity VARCHAR2(20), Primary Key (HDoid)) Cluster HD\_Cluster(HDoid); CREATE TABLE HD\_Contr ( HDoid VARCHAR2(10) NOT NULL, HD\_Contr\_id VARCHAR2(10) NOT NULL, Description VARCHAR2(25), Primary Key (HD\_Contr\_id), Foreign Key (HDoid) References Harddisk (HDoid)) Cluster HD\_Cluster(HDoid); This book constitutes the refereed proceedings of the Second International Conference on Advances in Information Systems, ADVIS 2002, held in Izmir, Turkey, in October 2002. The 40 revised full papers presented together with four selected papers from a workshop on new information technologies in education were carefully reviewed and selected from 94 submissions. The papers are organized in topical sections on databases and data warehouses, information retrieval, information systems, multi-agent technologies and systems, evolutionary algorithms, system programming, and distributed and parallel processing
