Issues Related to Mobile Database System


Book Description

As the popularity of electronic commerce and maturity of wireless technology increase continuously through which mobile users can access the internet anytime anywhere without having to physically hook up any access point. However protocol, physical constraints, security and cost may still limits communication - it will not be possible to establish online communications for as long as they want, whenever they want. So there is a strong need for developing mobile database system for mobile devices. In this way mobile database opens up a new chapter and provided solutions to this restrictions. There is also support of the real time database system depending upon the timing constraints pulls the mobile database concepts which emerges them in a new form of technology as mobile distributed real time database systems. This paper sheds light on mobile database systems and issues related to MDRTDB.

Data Management for Mobile Computing


Book Description

Earth date, August 11, 1997 "Beam me up Scottie!" "We cannot do it! This is not Star Trek's Enterprise. This is early years Earth." True, this is not yet the era of Star Trek, we cannot beam captain James T. Kirk or captain Jean Luc Pickard or an apple or anything else anywhere. What we can do though is beam information about Kirk or Pickard or an apple or an insurance agent. We can beam a record of a patient, the status of an engine, a weather report. We can beam this information anywhere, to mobile workers, to field engineers, to a track loading apples, to ships crossing the Oceans, to web surfers. We have reached a point where the promise of information access anywhere and anytime is close to realization. The enabling technology, wireless networks, exists; what remains to be achieved is providing the infrastructure and the software to support the promise. Universal access and management of information has been one of the driving forces in the evolution of computer technology. Central computing gave the ability to perform large and complex computations and advanced information manipulation. Advances in networking connected computers together and led to distributed computing. Web technology and the Internet went even further to provide hyper-linked information access and global computing. However, restricting access stations to physical location limits the boundary of the vision.




Current Issues in Databases and Information Systems


Book Description

The East European Conference on Advances in Databases and Information - stems (ADBIS) is the successor of the annual International Workshops with the same title that during 1993{1996 were organized in Russia by the Moscow ACM SIGMOD Chapter. Initiated in St. Petersburg, Russia, in 1997, it con- nued in Poznan, Poland, in 1998 and in Maribor, Slovenia, in 1999. The ADBIS Conference became the premier database and information systems conference in Eastern Europe. It intended to increase interaction and collaboration b- ween researchers from the East and the West, and to provide an internationally recognized tribune for the presentation of research results. The International Conference on Database Systems for Advanced Appli- tions (DASFAA) was rst held in Seoul, Korea, in 1989 to promote database research and development activities in Asian and Australasian countries. The Special Interest Group of Database Systems (SIGDBS) of the Information P- cessing Society of Japan (IPSJ) and the Special Interest Group of Data Base (SIGDB) of Korea Information Science Society (KISS) had important roles in the organization of DASFAA. Since that time the DASFAA has been held e- ry two years: Tokyo in 1991, Daejon in 1993, Singapore in 1995, Melbourne in 1997, and Taiwan in 1999. The DASFAA became one of the most prestigious international conferences ever held in Asia or Australasia.

Mobile Data Management


Book Description

Welcome to the Second International Conference on Mobile Data Management (MDM2001). The conference serves as a forum for the exchange of technical ideas and research results in the areas of mobility and database management. This year, we have a very exciting program for MDM2001. Many quality papers were submitted to the conference. All of the submitted papers were - viewed by at least three PC members. Due to the limitations of the program schedule as well as the desire to organize the conference using a single track format, we selected only 18 papers for full presentation at the conference. As a result many excellent papers could not be accepted. The papers chosen for presentation span a large range of topics, from n- work protocol issues up to the semantics of mobile applications. The common theme of all these papers is their recognition of the central role played by data managementtechniques in the developmentof the emerging worldof mobile and wireless applications. We have loosely organized these papers into six areas: 1. DATA MANAGEMENT ARCHITECTURES, 2. CONTENT DELIVERY, 3. DATA BROADCASTING, 4. CACHING AND HOARDING, 5. COPING WITH MOVEMENT, 6. NETWORKS AND SYSTEMS ISSUES In addition to the researchtrack, we havesought to broaden the scope of the conference with an industrial session as well as poster presentations. Overall, the program strikes a comfortable balance between applied and theoretically oriented papers.




Object Management in Distributed Database Systems for Stationary and Mobile Computing Environments


Book Description

N etwork-based computing domain unifies all best research efforts presented from single computer systems to networked systems to render overwhelming computational power for several modern day applications. Although this power is expected to grow with respect to time due to tech nological advancements, application requirements impose a continuous thrust on network utilization and on the resources to deliver supreme quality of service. Strictly speaking, network-based computing dornain has no confined scope and each element offers considerable challenges. Any modern day networked application strongly thrives on efficient data storage and management system, which is essentially a Database System. There have been nurnber of books-to-date in this domain that discuss fundamental principles of designing a database systern. Research in this dornain is now far matured and rnany researchers are venturing in this dornain continuously due to a wide variety of challenges posed. In this book, our dornain of interest is in exposing the underlying key challenges in designing algorithms to handle unpredictable requests that arrive at a Distributed Database System(DDBS) and evaluating their performance. These requests are otherwise called as on-line requests arriving at a system to process. Transactions in an on-line Banking service, Airline Reservation systern, Video-on-Demand systern, etc, are few examples of on-line requests.




Real-Time Database Systems


Book Description

In recent years, tremendous research has been devoted to the design of database systems for real-time applications, called real-time database systems (RTDBS), where transactions are associated with deadlines on their completion times, and some of the data objects in the database are associated with temporal constraints on their validity. Examples of important applications of RTDBS include stock trading systems, navigation systems and computer integrated manufacturing. Different transaction scheduling algorithms and concurrency control protocols have been proposed to satisfy transaction timing data temporal constraints. Other design issues important to the performance of a RTDBS are buffer management, index accesses and I/O scheduling. Real-Time Database Systems: Architecture and Techniques summarizes important research results in this area, and serves as an excellent reference for practitioners, researchers and educators of real-time systems and database systems.
