Application of Dynamic Fragmentation Methods in Multimedia Databases: A Review
(MDPI Publishing, 2020-11-30)
Fragmentation is a design technique widely used in multimedia databases, because it produces substantial benefits in reducing response times, causing lower execution costs in each operation performed. Multimedia databases ...
Horizontal Fragmentation of Data Warehouses Using Decision Trees
(Universidad Autónoma de Coahuila, Centro de Investigación en Matemáticas Aplicadas, 2020-08-01)
One of the main problems faced by Data Warehouse (DW) designers is fragmentation. Several studies have proposed data mining-based horizontal fragmentation methods, which focus on optimizing the query response time and ...
Towards Association Rule-based Item Selection Strategy in Computerized Adaptive Testing
(CEIPA, 2020-12-07)
One of the most important stages of Computerized Adaptive Testing is the selection of items, in which various methods are used, which have certain weaknesses at the time of implementation. Therefore, in this paper, it is ...
Comparative Analysis of Decision Tree Algorithms for Data Warehouse Fragmentation
(CEIPA, 2020-12-07)
One of the main problems faced by Data Warehouse designers is fragmentation. Several studies have proposed data mining-based horizontal fragmentation methods. However, not exists a horizontal fragmentation technique that ...
FRAGMENT: A Web Application for Database Fragmentation, Allocation and Replication Over a Cloud Environment
(IEEE, 2020-05-25)
Fragmentation, allocation and replication are techniques widely used in relational databases to improve the performance of operations and reduce their cost in distributed environments. This article shows an analysis of ...
Design of a Multimedia Data Management System that Uses Horizontal Fragmentation to Optimize Content-based Queries
(International Academy, Research, and Industry Association (IARIA), 2020-10-01)
In the Technological Institute of Orizaba, a project was carried out to collect historical data of the Institute, where a large amount of multimedia data was retrieved. At the end of the project, it was detected that ...
