OSI management standards define management information with a set of templates using object-oriented concepts. In order to manage heterogeneous systems, each managed system needs to implement the MIB defined in OSI. From an implementation standpoint, software for both managing and managed systems must be built up efficiently, according to the management information actually available within the management domain. The authors developed a tool called MINT (Management INformation support Tool) which generates programs for accessing management information from the network management information template notation. They present the design criteria, functionalities, software structure for management applications and the structure of MIB and its tool MINT.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

The full semantics of many database applications cannot be understood without combining the database's data semantics from a logical model of data L with data semantics embedded in a file-system model F and in a physical storage model P. To prove this assertion, the authors use proof by contradiction on its negation. Two examples are provided to demonstrate false positives, multidatabases with identical logical models L which are not interoperable, one due to differences in F and the other in P. One example is provided to demonstrate a missing value, an interoperable database without an explicit logical model L, but rich in semantics desirable from its file-system model F. A technique is proposed for describing how semantics embedded in L, F and P can be combined.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

Approaches which are based on integrated mechanisms are obviously intractable (if not impossible) within a large size environment. The authors propose an approach where users are allowed to dynamically investigate information and incrementally specify their views. The idea is to use a functional approach to model the construction of views. Further, their approach provides a mechanism by which views adapt to the evolution of the information space. This mechanism relies on dynamic triggers to fulfil this goal.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

Integration of heterogeneous data repositories by using object-oriented views 通过使用面向对象的视图集成异构数据存储库

The author defines an object-oriented view mechanism which allows integrated views to be defined starting from local views which are expressed in a uniform object-oriented data model, but still semantically heterogeneous. A view model based on the object-oriented paradigm has several advantages, since it is a semantically rich model and allows object behavior to be described by using methods. This allows several semantic conflicts to be solved on a structural basis, that is, the model naturally supports the structural mapping approach traditionally used in heterogeneous distributed database systems. Moreover, the usage of methods allows complex mapping to be defined, when the structural mapping cannot be used. The proposed view model uses mechanisms for method combination similar to those defined in some object-oriented programming languages. These mechanisms allow an integrated view to reuse and extend methods defined for the various local views.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

Also, knowledge-based systems are usually tailored towards specific applications. The need and advantages of integrating different knowledge-based systems is widely acknowledged. However, the use of different knowledge representation schemes requires each user to learn each scheme to effectively use the systems. But users are more productive, competitive, and feel encouraged to use different systems when the underlying tool disparities are hidden. Techniques for integrating knowledge-bases in distributed settings, without hindering the simultaneous access to local (native) representations, are addressed. The techniques are based on the clustering of knowledge-base data entities. The different entity clusters are then represented using a generic scheme for the integration step. In essence, the clustering and generic schemes provide a common framework for laminating the differences in representations of the entities in the respective knowledge-bases.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

Instead of using the traditional approach of executing global transaction by remotely accessing distributed data, they propose that transactions be executed locally, and data is dynamically migrated to the appropriate sites. Thus, they eliminate the need for global transactions. Since there are no global transactions, the problem of distributed commitment does not arise. This is an important issue related to database recovery that is often ignored by protocols for transaction processing in heterogeneous databases. A special protocol is executed for migrating data objects. They present a protocol for localizing the access of a data object.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.
