Preserving data replication consistency through ROWA-MSTS

In modern distributed systems, replication receives particular aware�ness to provide high data availability, reliability and enhance the performance of the system. Replication becomes as significant mechanism since it enables organizations to provide users with admission to current data where and when they need it. Integrated VSFTPD with Read-One-Write-All Monitoring Syn�chronization Transaction System (ROWA-MSTS) has been developed to moni�tor data replication and transaction performs in distributed system environment. This paper presents the ROWA-MSTS framework and process flow in order to preserve the data replication consistency. The implementation shows that ROWA-MSTS able to monitor the replicated data distribution while maintain�ing the data consistency over multiple sites

A random search based effective algorithm for pairwise test data generation

Testing is a very important task to build error free software. As the resources and time to market is limited for a software product, it is impossible to perform exhaustive test i.e., to test all combinations of input data. To reduce the number of test cases in an acceptable level, it is preferable to use higher interaction level (t way, where t ≥ 2). Pairwise (2-way or t = 2) interaction can find most of the software faults. This paper proposes an effective random search based pairwise test data generation algorithm named R2Way to optimize the number of test cases. Java program has been used to test the performance of the algorithm. The algorithm is able to support both uniform and non-uniform values effectively with performance better than the existing algorithms/tools in terms of number of generated test cases and time consumption

EasyA: Easy and effective way to generate pairwise test data

To reduce the number of test cases in an acceptable level, it is preferable to use higher interaction level (t way, where t = 2). Pairwise (2- way or t = 2) interaction can find most of the software faults.

Java program has been used to test the performance of the algorithm. The performance is better than the existing algorithms/tools in terms of number of generated test cases and time consumption

Learning management system through assignment box alert

Learning Management System (LMS) is software that has been developed for the administration, documentation, tracking, and reporting the educational resources. Assignment Box Alert (ABA) is a type of LMS which has been developed to manage the student in assignment submission. Before the development of ABA, the submission assignments from the students to lecturer have been done manually either through the hardcopy by printing material or softcopy by using the compact disc. The manual system consumes lot of time, besides quite easily being damaged or misplace. In this project, the development of ABA using the Remote Method Invocation has able to manage the assignment submission efficient and effectively. This is due the transferred file by student can be view more systematically by the lecturer, while at the same time the notification from the system remind the student to upload assignment on time
