Motivation Modem enterprises rely on database management systems
(DBMS) to collect, store and manage corporate data, which is
considered a strategic corporate re source. Recently, with the
proliferation of personal computers and departmen tal computing,
the trend has been towards the decentralization and distribution of
the computing infrastructure, with autonomy and responsibility for
data now residing at the departmental and workgroup level of the
organization. Users want their data delivered to their desktops,
allowing them to incor porate data into their personal databases,
spreadsheets, word processing doc uments, and most importantly,
into their daily tasks and activities. They want to be able to
share their information while retaining control over its access and
distribution. There are also pressures from corporate leaders who
wish to use information technology as a strategic resource in
offering specialized value-added services to customers. Database
technology is being used to manage the data associated with
corporate processes and activities. Increasingly, the data being
managed are not simply formatted tables in relational databases,
but all types of ob jects, including unstructured text, images,
audio, and video. Thus, the database management providers are being
asked to extend the capabilities of DBMS to include
object-relational models as well as full object-oriented database
man agement systems.
