Research And Realization Of The Network Cooperating Learning Resource Database

This dissertation analyzes the deficiency of consisting in the building and useing of the currency learning resource database with enlightened by the blog.This dissertation gropes for the idea of combining the weblog with the building process of the resource database.It investigates the theory of building the learning resource database that based on the struts framework and the persistent database with the hibernate technology.And then,it discusses the technology of lucene searching application.Finally.it discusses the progress of building the practical system based on the scholastic demand.Exists in the traditional teaching, cooperation learning is an important learning pattern.It is useful for extending the students' perceive ability and enhancing them cooperating power. However,it is very inhibitable in the traditional learning. Currently,it demand limited space time and centralized personnel all together.It can't exert the personality. No other than the network break through the localization. Consequently it lays out the real cooperation learning.With the development of the network courses,many university have builded abundant teaching database.Those abundant teaching database are one of the essential in the teaching pattern and the base of the network course.Those database include multimedia materials, coursewares, cases, test questions and so on.Whereas,those type of teaching database prevalently have a problem that the content of those database are static storaged. Namely,that was one-offuploaded by the teacher an the programmer. With the eyes of the development aspect, as a whole,that is unilateral and one-off uploaded.The teachers and the students lie in the opposite position.they act in the dissimilitude role. Plenty of the completed teaching database have abundant information,but those are renewal slowness and in defect of attraction.Tthe problem is that the traditional databases are deficiency of intercommunion and dynamic enlarging capability.This dissertation's thinking originates from the web log that was said as the Magellan of the information era.This new type of the cooperating network media is the knowledge management system of the intercommunion.lt can accelerate the students to personality expression and to filter information and to deepnessly intercommunion.lt can also promote the students to discover,speculate and express the problem.lt is not only the verify of the study progress but also the the personality knowledge management system.With this tool,the students can organicly combine these work and study all together.And they can accumulate more and more information and apply in those intercommunion and communion to acquire the thinking inspiration. Hereby,we can organicly combine the weblog with the network teaching database to optimize the study progress.Implementing the network cooperating learning resource database must go through many step.Which are organizing the originality matter, collectiviting design, designing the database pattern,modeling with uml technology, programme, testing and so on. For the sake of optimizing the progress of building and choose the technology.For the sake of separating the art designer and the programmer's task,I use the third class framework to denote the data and object of this system. And I use the mature framework of Java technology to apply in the building progress.I encapsulate the core function with the pattern an the module.The database and the web interface are detached. So the system are entirely different,it is no longer helpless.In the presentation layer,struts framework has the characteristic of...
