Distributed database systems are essential to modern computing. Such infrastructures offer scalability, speed, fault tolerance, and security, enabling applications analyse massive data volumes in real time. Some of the difficulties designing maintaining a distributed system include consistency, performance, complexity, cost. A must be carefully planned, constructed, managed order address these ...

The purpose of this paper is to present an introduction to Distributed Database. It contains two main parts: first one is fundamental concept in Distributed Database and second one is Different technique use in Distributed Database. Database with a production of huge data sets and their processing in real-time applications, the needs for environmental data management have grown significantly. M...

Invention of XML as a universal standard for data representation triggered enormously wide efforts for its adaptation into almost every IT activity. Databases took one of the focusing places of the XML research. This paper investigates the development path of XML from its origins to its current place in distributed database systems. Through enumeration of features and analysis of the problems r...

The database summarization system coined SEQ provides multi-level summaries of tabular data stored into a centralized database. Summaries are computedonlinewith a conceptual hierarchical clustering algorithm. However, in many companies, data are distributed among several sites, either homogeneously (i.e. , sites contain data for a common set of features) or heterogeneously (i.e. , sites c...
