Recently, there is an increasing use of CORBA implementation in developing multidatabase systems. MIND and Panorama are some of the examples of multidatabase prototypes that have been implemented on the top of CORBA compliant namely ObjectBroker and VisiBroker respectively. They both aim to achieve interoperability among Oracle, Sybase and other different DBMSs through the registration of these DBMSs to them using CORBA. This registration to a CORBA-based multidatabase system offers an advanced way in achieving interoperability. We first introduce Panorama multidatabase system and discuss the basic implementation decisions in registering different DBMSs using the CORBA compliant ORB, namely VisiBroker to this system. Then, it aims to discuss the method we've used in registering different DBMSs to our designed multidatabase system-Panorama. A detailed discussion about the registration of Oracle8 and Sybase is given. And finally, a conclusion and the future work for this system have been given.

“…Accessing and managing data from such heterogeneous databases pose complex problems that can be classified into platform, DMS, location and semantics level [2]. The platform level copes with the fact that databases reside on different brands of hardware, under different operating systems, and interacting through various network protocols.…”

Accessing and managing data from several existing independent databases pose complex problems that can be classified into platform, DMS, location and semantic levels. This paper describes a general architecture, a methodology and a CASE environment intended to address the problem of providing users and programmers with an abstract interface to independent heterogeneous and distributed databases. The architecture comprises a hierarchy of mediators that dynamically transform actual data into a virtual homogeneous database. Each layer provides a certain kind of independence. The InterDB approach provides a complete methodology to define this architecture, including schema recovery through reverse engineering, database integration and mapping building. The methodology is supported by the DB-MAIN CASE tool that helps to generate the mediators and their repository.

Database schema integration is significant not only in building multidatabase systems but also in data warehousing.Metaduta, which de3ne schenzas, are normally involved in the surrounding issues. And while many of these issues have been addressed in the past, unresolved issues remain. In this paper; we present an approach that not only uses metadata but also uses meta-meta information to make schema integration more possible. Our solution requires metu object facilit). that serves not only as a repository but also as a more feasible means of nianaging meta data. We also advocate the use of such a facility as part of an object-oriented middleware environment that provides an open inte$ace standard and several useful services in distributed object management.
