چکیده

Administrative issues are of vital importance to organizations adopting distributed database technology. Most research systems and emerging commercial DDBMSs have assumed site autonomy as a guiding principle. This paper presents some general problems associated with autonomy and administration in a DDBMS, and discusses the incompatibility between replication transparency and site autonomy. In a DDBMS which supports replication transparency, the degree of site autonomy in a system should properly be a policy decision made by system administrators. Parameterization of the degree of site autonomy in a DDBMS involves careful design of a mechanism involving storage structures, operations, and authorization. A mechanism which extends the ANSI SQL authorization model is described, and examples of how users can use the mechanism to implement both centralized and decentralized administration policies are presented.

Scalable Storage for a Dbms Using Transparent Distribution Scalable Storage for a Dbms Using Transparent Distribution

Scalable Distributed Data Structures (SDDSs) provide a self-managing and self-organizing data storage of potentially unbounded size. This stands in contrast to common distribution schemas deployed in conventional distributed DBMS. SDDSs, however, have mostly been used in synthetic scenarios to investigate their properties. In this paper we concentrate on the integration of the LH* SDDS into our...

Distributed Databases

A distributed database (DDB) is a collection of multiple, logically interrelated databases distributed over a computer network. A distributed database management system (distributed DBMS) is the software system that permits the management of the distributed database and makes the distribution transparent to the users [1]. The term Òdistributed database systemÓ (DDBS) is typically used to refer ...

Robustness Analysis of Distributed Databases via Fault Injection

As the importance of reliable data storage increases, various techniques are applied to obtain the reliabilities. The usage of the assumed fault tolerant cloud providers increases, even though not a sufficient amount of research is performed on their fault tolerance. On cloud servers, a distributed Database Management System (DBMS) can be used to achieve safe data storage. Various DBMSs are mak...
