Abstract:
Today, many business applications continue the
ongoing creation of separated data stores; data
mining often requires data integration for those data.
This process becomes significant in a variety of
situations both commercial and scientific. The main
contribution of data integration system is that user
can focus on specifying what data they want rather
than on describing how to obtain it. This paper
proposes a system for integrated access to data that
are related, but exist in separated databases. In this
system, a data integration tool is created for different
data that are stored in different databases. This
system will make integrated access based on
participant databases' export schemas by using data
dictionary and type dictionary. Each export schema
contains information about attributes containing in
each database. This system also defines attribute
names, attribute types, and attribute length for tables
that user wants to integrate and gives integrated
results to user.
