An improved vertical fragmentation, allocation and replication for enhancing e‐learning in distributed database environment

Abstract

E-learning is the indispensable technique to educate huge number of people and students in short period of time with optimized usage of different kind of required resources. It is employed as a crucial teaching approach by almost all kind of educational institutions all around the world. Since e-learning involves significant amount of resource utilization and cost, it requires some essential methodology to enhance the current system of e-learning more efficient. The mere publication of the educational content in websites is not enough. It is very clear that, without applying suitable strategic models and concepts and establishing appropriate communication channels between contributors of e-learning system, the educational goals cannot be achieved as we desired. Distributed database involves greater contribution in the field of cloud based e-learning process. Basically, data replication is crucial decision of companies as database distribution can be achieved effectively by the method of database replication which generates the same copies of information called replicas. In this article, we analyze the supremacy of synergetic learning and concentrates on data replication's significance in cloud based learning system. Here we propose an excellent mechanism for data replication and enhancing the performance in terms optimized access

Optimal Allocation of Mobile Learning Resources Based on a Complex Network

“…If d=3, the grey number μ3 of the general class belongs to [0, 3,6], and the corresponding whitening weight function can be expressed as:…”

“…Under the deep integration between information technology and education, centralized online learning can no longer meet the fragmented learning needs of learners [1][2][3][4][5][6]. Take English learning for example.…”

“…Take English learning for example. The learners can make full use of the scattered time to practice listening training, vocabulary recitation, and short passage reading, while achieving a very high learning efficiency [7][8][9][10]. Therefore, mobile learning methods based on mobile terminal devices are increasingly favored by learners.…”

Integration Construction of Teaching Resource Library for Art and Design Majors under Interactivity Orientation

“…Literature [14] investigated and analyzed the situation of students' utilization of teaching online resource libraries, and found that students search and answer questions on the resource library for the difficulties they encountered in learning is the most common. Literature [15] summarized the advantages of e-collaborative learning, which supports students' access to accurate and rich teaching database resources, has the characteristics of fast response and high efficiency, and finally introduced a data replication strategy to optimize this e-collaborative learning system.…”
