Abstract:
Data integration is becoming an important issue for organizations in the recent years, so as to
allow these organizations cooperate and exchange information with each other.
Unfortunately; there are many conflicts which prevent the data integration. One of the
possible solutions to this problem is integration of the different component databases for
building a global unified schema.
Schema integration is an approach to overcome all these conflicts and achieve data integration.
This study will survey the conflicts that occur in different component schemas and resolve
these conflicts then it concentrates on attribute entity conflict which represented the research
problem. In addition to it explains schema integration process in multidatabase systems.
This work will propose a mechanism to resolve attribute entity conflict and support the
solution with explanation example and it investigates a common approaches which are use to
resolve the attribute entity conflict then it explains these solutions with explanation examples.
Finally this thesis presents a comparative analysis of common approaches which are used to
resolve attribute entity conflict according to many criteria.
