“…In this paper we do not discuss on local schemas integration. Please see the details work of [2,3,4,5,6,7,8,9,10,12]. The schema contains the format, structure, and organization of the data in a system.…”

“…Creating and maintaining the global schema, which requires the use of database integration techniques, is a critical issue in multidatabase systems. A variety of approaches to schema integration have been proposed; e.g., [2,3,4,5,6,7,8,9,10,12]. The main schema integration problem is associated with combining diverse schemas of the different databases into a coherent global view by reconciling any structure or semantics conflicts between the local component databases [7].…”

“…Hence, it is a nature choice for a canonical model [7]. In general, tightly coupled systems integrate the diverse sources of intelligence through a global conceptual scheme, normally denominated canonical model, providing a uniform vision of the diverse component at a high level [8]. The use of a canonical model hides the structural differences between the different components and gives to the user the illusion to be accessing a simple centralized database.…”

One of the challenging problems in the multidatabase systems is to find the most viable solution to the problem of interoperability of distributed heterogeneous autonomous local component databases. This has resulted in the creation of a global schema over set of local component database schemas to provide a uniform representation of local schemas. The main objective of this paper is to maintain the Global Schema and the Global Directory/Dictionary/Metadata as the local schemas are autonomous and evolve over time. In this paper we consider uniform object-oriented data models which is used during integration of different heterogeneous distributed databases from different data models and proposed a framework to maintain an objected-oriented Global Schema in the multidatabase system.The Bottom up local schema modifications propagation in the Global schema is proposed and during this process the Global Directory/Dictionary/Metadata is maintained without manual intervention.
