A2A: An Architecture for Autonomic Management Coordination [chapter]

Alexander V. Konstantinou, Yechiam Yemini
2009 Lecture Notes in Computer Science

Development of an autonomous heterogeneous distributed database system: DHIM

Haeng Rae Cho, Yoo Sung Kim, Songchun Moon
1993 Microprocessing and Microprogramming  
Therefore, any database system can be federated into DHIM as an element database system.  ...  In this paper, we design and implement a prototypical heterogeneous distributed database system, named DHIM (Distributed Heterogeneous Information Management).  ...  The open architecture means that DHIM operates independently from local database systems (LDBSs). Therefore, any database system can be federated under DHIM as an LDBS.  ...

Federated database management system: Requirements, issues and solutions

Magdi N Kamel, Nabil N Kamel
1992 Computer Communications  
In this paper we discuss an approach, known as the federated database approach, that allows users and applications to access and manipulate data across several heterogeneous databases while maintaining  ...  In particular, we address the design issu~s from three angles: transaction management, system archl.tecture, and schema integration.  ...  2 • Under this approach each local database is considered a logical component in the federation.  ...

Federated database systems for managing distributed, heterogeneous, and autonomous databases

Amit P. Sheth, James A. Larson
1990 ACM Computing Surveys

Maintaining Global Integrity in Federated Relational Databases Using Interactive Component Systems [chapter]

Christopher Popfinger, Stefan Conrad
2005 Lecture Notes in Computer Science  
The maintenance of global integrity constraints in database federations is still a challenge since traditional integrity constraint management techniques cannot be applied to such a distributed management  ...  In this paper we present a concept of global integrity maintenance by migrating the concepts of active database systems to a collection of interoperable relational databases.  ...  An ACDBS is an autonomous component database system or component system (CDBS or CS) of a federated database system as described in [2] .  ...

Transaction Management in a Mobile Data Access System [chapter]

K. SEGUN, A.R. HURSON, V. DESAI, A. SPINK, L.L. MILLER
2001 Annual Review of Scalable Computing  
Within the scope of distributed databases and multidatabases, the issue of concurrency control as a means to provide timely and reliable access to the information sources has been studied in detail.  ...  In an MDAS environment, concurrent execution of transaction is more problematic due to the power and resource limitations of computing devices and lower communication rate of the wireless communication  ...  This implies that the databases at the sites are not autonomous. In contrast, the local database at the local sites in a multidatabase are autonomous.  ...
