  A FRAMEWORK FOR PROCESSING K-BEST SITE QUERY Yuan-Ko Huang* and Lien-Fa Lin Department of Information Communication Kao-Yuan University; Kaohsiung Country, Taiwan R.O.C. ABSTRACT A novel query in spatial databases is the K-Best Site Query (KBSQ for short). Given a set of objects O, a set of sites S, and a user-given value K, a KBSQ retrieves the K sites from S such that the total distance from each object to its closest site is minimized. The KBSQ is indeed an important type of spatial queries with many real applications. In this paper, we investigate how to efficiently process the KBSQ. We first propose a straightforward approach with a cost analysis, and then develop the K Best Site Query (KBSQ) algorithm combined with the existing spatial indexes to improve the performance of processing KBSQ. Comprehensive experiments are conducted to demonstrate the efficiency of the proposed methods.   KEYWORDS   spatial databases; K-Best Site Query; spatial indexes Ful...

  HIGH AVAILABILITY AND LOAD BALANCING FOR POSTGRESQL DATABASES: DESIGNING AND IMPLEMENTING. Pablo Bárbaro Martinez Pedroso Universidad De Las Ciencias Informáticas, Cuba ABSTRACT The aim of the paper is to design and implement an approach that provides high availability and load balancing to PostgreSQL databases. Shared nothing architecture and replicated centralized middleware architecture were selected in order to achieve data replication and load balancing among database servers. Pgpool-II was used to implementing these architectures. Besides, taking advantage of pgpool-II as a framework, several scripts were developed in Bash for restoration of corrupted databases. In order to avoid single point of failure Linux HA (Heartbeat and Pacemaker) was used, whose responsibility is monitoring all processes involved in the whole solution. As a result applications can operate with a more reliable PostgreSQL database server, the most suitable situation is for applications with mo...

  MAPPING COMMON ERRORS IN ENTITY RELATIONSHIP DIAGRAM DESIGN OF NOVICE DESIGNERS Rami Rashkovits1 and Ilana Lavy2 1Department of Management Information Systems, Peres Academic Center, Israel 2Department of Information Systems, Yezreel Valley College, Israel ABSTRACT Data modeling in the context of database design is a challenging task for any database designer, even more so for novice designers. A proper database schema is a key factor for the success of any information systems, hence conceptual data modeling that yields the database schema is an essential process of the system development. However, novice designers encounter difficulties in understanding and implementing such models. This study aims to identify the difficulties in understanding and implementing data models and explore the origins of these difficulties. This research examines the data model produced by students and maps the errors done by the students. The errors were classified using the SOLO taxonomy. ...

  A SEMANTIC RESOURCE BASED APPROACH FOR STAR SCHEMAS MATCHING Elhaj Elamin1Amer Alzaidi2 and Jamel Feki2 1Department of Computer Science, Sudan University of Science and Technology, Khartoum, Sudan 2University of Jeddah, FCIT, Jeddah, Saudi Arabia ABSTRACT The hybrid approach is widely used in constructing data warehouse (DW) schemas. It relies on a complex process for matching two sets of multidimensional star schemas: schemas built from business requirements (BR-Star schemas) and schemas constructed on the organization data source (DS-Star schemas). Using a semantic resource during this matching helps solving heterogeneity problems. This paper suggests a semiautomatic approach for the construction of approved star schemas by matching DS-Star schemas with BRStars, and by using WordNet as a semantic resource for solving heterogeneity issues. This approach consists of three steps: i) Match DS-Stars with BR-Stars; ii) Involve the DW designer for approval of the matching proc...
