A Simple Framework for Contracts in Federated Database Systems
نویسندگان
چکیده
A federated database system is a collection of organizations, called a federation, and a collection of databases belonging to the organizations. Members of the federation can enter into contracts that specify how data is shared between the databases of the system. An important issue is how the contracts interact with one another. This paper presents a simple framework for writing contracts in federated database systems that limits contract interaction, and thereby, makes it possible to detect contention between contracts.

An Overview about the DynaQuest Framework
The DynaQuest-Framework should reduce the effort for the creation of Internet-based virtual databases. These virtual databases are a special kind of federated database systems where the sources are no fully-fledged databases with a query language but rather simple and restricted data provider, like web-form-based sources (”hidden web”) or web services. To support the development of these system...

Today, data plays an essential role in all levels of human life, from personal cell phones to medical, educational, military and government agencies. In such circumstances, the rate of cyber-attacks is also increasing. According to official reports, data breaches exposed 4.1 billion records in the first half of 2019. An information system consists of several components, which one of the most im...
متن کاملA UML/OCL Framework for Design of Mediated Data Federations
This paper describes a general semantic framework for precise specification of so-called mediating systems; such systems provide for tight coupling on a global level of a collection of heterogeneous component databases to a federated database. A mediating system maps in a uniform and systematic manner the underlying database schemas of the component systems to a separate, newly defined integrat...
متن کاملObject-Oriented Modeling and Design of Database Federations
We describe a logical architecture and a general semantic framework for precise specification of so-called database federations. A database federation provides for tight coupling of a collection of heterogeneous component databases into a global integrated system. Our approach to database federation integrates in a uniform and systematic manner the underlying database schemas of the component l...
متن کاملOptimization of Continuous Queries in Federated Database and Stream Processing Systems
The constantly increasing number of connected devices and sensors results in increasing volume and velocity of sensor-based streaming data. Traditional approaches for processing high velocity sensor data rely on stream processing engines. However, the increasing complexity of continuous queries executed on top of high velocity data has resulted in growing demand for federated systems composed o...
