The authors propose a security control mechanism for MDBS based on multilevel security concept. The proposed security control mechanism provides the database administrators or security control officials of the MDBS and its component DBS with richer facilities for defining security constraints on the data items to be shared by the multidatabase system users. Furthermore, the security control mechanism can be implemented as a stand-alone front-end of component database systems so that it can be easily integrated into or decoupled from the MDBS.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

The goal of the system is to provide facilities for multidatabase applications for accessing and manipulating multiple autonomous heterogeneous object-oriented, relational and other databases. This paper gives an overview of the architecture, describes the common object model and gives the justification for adapting the model for a multidatabase system. It describes the database environment of the system, discusses how to manage schemas consisting of types and functions from multiple databases. It briefly describes the features of the data language and gives an example. It discusses a method for dealing with object identification issues in a multidatabase system, reviews schema integration issues and briefly mentions schema mapping to relational models.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

The irresistible move towards interoperable database systems 不可抗拒地向可互操作的数据库系统发展

Cannata","doi":"10.1109/IMS.1991.153678","DOIUrl":"https://doi.org/10.1109/IMS.1991.153678","url":null,"abstract":"The successful use of interoperable database technology in major applications has not been widespread to date. This situation is rapidly changing to one where applications commonly share data resources and isolated application/data pairs may soon be the exception. The move to these applications with interoperable database systems is irresistible for a variety of reasons: corporate data, which has been accumulated across global corporate operations on various incompatible systems, is now recognized as a strategic asset; there is a growing willingness by competing information system vendors to cooperate; the emergence of OSI as a useful tool may mean that communication aspects of computers can be viewed as a commodity; and dramatic changes in the world-wide telecommunications fabric will be seen in the 1990s. MCC has a project called Carnot that is doing the research necessary to develop tool that will allow development of open applications that can be tightly integrated with information stored on existing, closed systems. These tools will allow participants to achieve efficient implementations of architectures such as Bellcore's OSCA. The purpose of the Carnot system is to provide for the integration of a variety of resources within an enterprise and ultimately, across global enterprises.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

Bridging the boundaries between applications: providing interactive interoperability for the end-user 弥合应用程序之间的界限:为最终用户提供交互式互操作性

YANUS offers a conceptual interface of data objects and operations, where the data objects correspond to data stored in a database and an operation corresponds to an operation in an underlying software package. A schema is used that determines the applicability of certain operations to certain data objects. To enable the user to apply operations to data objects in all cases where this application is allowed, the user interface is 'schema driven'. Knowledge about the schema is used to control and help the user in applying operations to data objects. So-called workspaces are used to give the user access to a restricted part of the data object space and a restricted cluster of operations. Other workspaces can be accessed in such a way that all allowed operations can be applied to all data objects. In this, the user does not have to transfer data explicitly, this being done automatically by YANUS. YANUS also provides for data transformation when necessary and invokes the operations. The integration is extensible, due to the knowledge based approach. A test-bed for the system is the integration of a package for interactive pattern analysis (ISPAHAN) with a DBMS (Ingres).<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

Understanding the real semantics of data is essential in schema integration in fully integrated heterogeneous database systems as well as in the interoperability of federated database systems. It has been pointed out that success in schema integration depends on understanding the semantics of the schema components (for example, attributes, relations, entity sets, relationship sets), and the ability to capture and reason with the semantics. Traditionally, the determination of attribute relationships is an 'artcraft work', which is done manually by database administrators (DBAs). The objective of this paper is to determine attribute relationships semi-automatically.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

The aim of the developing database system is to provide high level extensibility and customizability to support various applications. The authors provide a set of functions of OODB as an extensible toolkit called from application programming languages. An SQL-like query language for OODB query function is based on this toolkit. The language system is mainly for ad-hoc query application. One of the features of the language system is to provide RPC (remote procedure call) based programming interface for method call and query processing. Client-sever model is used for remote database accesses. The database toolkit is also implemented using RPC interface and used to customize several levels of DBMS functions. OODB management can provide a good environment for sharing and reusing of tools.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

Developed at Lotus, DataLens was designed to support access from both decision support and transaction-oriented applications to a broad spectrum of backend servers and data sources. Differences in access protocols are transparent to both the application and its end user. The specification permits DataLens applications to leverage advanced database server features if desired, without requiring that all data sources supply these features. This paper covers the DataLens architecture, how it copes with differences in server capabilities, and how it compares with other approaches to heterogeneous data access.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.
