Distributed database system technology is one of the major recent development in database systems area. With the introduction of commercial products, expectations are that distributed database management systems (distributed DBMSs) will by and large replace centralized ones within the next decade. This tutorial provides an overwiew of the technology, reflects on its promises and comments on the...

In this paper, we design and implement a prototypical heterogeneous distributed database system, named DHIM (Distributed Heterogeneous Information Management). The objectives of DHIM are two-fold: one is to realize the global update synchronization mechanism which preserve the global serializability of concurrent executions and the local site autonomy in tightly coupled heterogeneous distribute...

An application processing center consists of a set of well-de ned, well-designed and well-tested applications that are dynamically executed over a period of time. We assume that there is a set of candidate distributed database designs each of which is optimal for some applications. The random execution of applications on a distributed database design is modeled as a discrete Markov process, and...

Distributed database systems, which continue to inspire new architectures and new applications, have great potential in the modern computing world. In this paper, we show that the newly-proposed cloud-dew architecture realizes the potential of distributed database systems in the unreliable network environment, and provides the possibility of websurfing without an Internet connection. Distribute...

java is an object-oriented program that has abundant open-source libraries for application development and 3d model rendering. spatial database is the database that can efficiently store and manage geographic information data though various spatial data management techniques. this paper explores the rationale of coupling java with spatial database to develop an effective platform for future bui...

Database is defined as collection of files or table, where as DBMS stands for Database Management System which is collection of unified programs used to manage overall activities of the database. The two dominant approaches used for storing and managing database are centralized database management system and distributed database management system in which data is placed at central location and ...

Distributed database system technology is one of the major developments in information technology area. It will continue to have a very significant impact on data processing in the upcoming years because distributed database systems have many potential advantages over centralized systems for geographically distributed organizations. The continuing interest in distributed database systems in the...

Scalable Transactions for Scalable Distributed Database Systems

Distributed Multimedia Database involves network technology, distributed control, security, and multimedia computing. This chapter discusses fundamental concepts and introduces issues of image database and digital libraries, video-on-demand systems, multimedia synchronization, as well as some case studies of distributed multimedia database systems. Requirements of multimedia database management...

This paper describes principles of the data communication in the distributed database system AD-DB developed by the authors. The database system is designed to function properly in such a complex and dynamic network as the VANET is. That way, vehicles connected to the VANET could distribute traffic related data to the others. The paper concludes by proposing a solution for security problems by ...
