Access controls for federated database environments - taxonomy of design choices
نویسندگان
چکیده
We provide a short survey on the terminology of database security in database federations and give, as the main task, a taxonomy of the major design choices concerning access control in database federations. The taxonomy is organized in the categories granularity, authorization, and access control. Additionally, the impact of distribution, heterogeneity and autonomy, three characteristics of database federations, is examined for each of the design choices.

Building a Federated Database: the Femus Experience
The increased avalaibility of various databases in large corporations has created the need to federate the databases into loosely coupled collections of autonomous systems to allow controlled sharing of information and at the same time preserve the autonomy of each participant. Traditional distributed database (DDB) research has provided the earliest solutions to information sharing in distribu...
متن کاملReducing Storage Costs for Federated Search of Text Databases
In environments containing many text search engines a federated search system provides people with a single point of access. When search engines are managed by independent organizations two key problems are discovering and representing the contents of each text database. Query-based sampling is a recent technique for discovering the contents of uncooperative databases so as to create database r...
متن کاملIntegrating Distributed Data Sources Using Federated Objects
We address the problem of integrating heterogeneous data sources for collaborative environments such as Groupware systems. Pre-existing related distributed data is modeled by a composite object, where each data source is treated as a fragment of the composite object. We define a collection of methods which allow manipulation of the related distributed data in a controlled and consistent manner....

Federated database systems are heterogeneous with respect to data models and query languages but also with repect to underlying operating systems and hardware platforms. Besides transformations on the semantic level conversions on the data representation and communication protocol level have to be done. In this paper, we present the Remote Cooperation System RCS which provides client/ server co...
متن کاملCoupling of FDBS and WfMS for Integrating Database and Application Systems: Architecture, Complexity, Performance
With the emergence of so-called application systems which encapsulate databases and related application components, pure data integration using, for example, a federated database system is not possible anymore. Instead, access via predefined functions is the only way to get data from an application system. As a result, retrieval of such heterogeneous and encapsulated data sources needs the comb...
