Abstract
Now-a -days, E-learning has become an important trend for education based on distance learning. The institutions of higher education have raised their interest in the educational services which is based on the internet and that is defined as E-learning. Virtual classroom is an e-learning system which is an open classroom for the distance learning people. It integrates with the WS (Web Service) technology to give the benefits of incorporate interfaces in the education environment. The main problem which is raised in the e-learning system that too classroom based is Scalability and the Extensibility. Also the e-learning mechanism initially begins with extracting and reviewing of web information from web logs. An efficient assessment of scalability and the extensibility will give a positive result for improving the systems of distance learning in future. E-learning is an effort which helps to learn with the help of electronic technology like internet. It also helps to follow the behaviors results of the learner and also from the review results. E-learning has become very famous because of its positive attitude which gives more flexibility to satisfy the learners. With the help of E-learning a candidate can get trained easily at any time as their wish and also at any place in the world. Moreover there are also some disputes like extensibility and scalability in e-learning which is optimized by utilizing the WS technology. The scalability is been monitored continuously based on the accessing of web information by different users. Also with the help of web log information the activities of the E-learning is been reviewed and is been extracted with the latest approach
Called Doubly Linked Tree. The purpose of utilizing this approach will make the system more Extensible. Therefore the
Information of mining is mostly utilized for tracking the candidates and also for decision making activity.
