CRITICAL SUMMARY OF ADVANCED DATABASE FUNCTIONS FOR DISTANCE EDUCATION SYSTEM: VIEW CLASSROOM
Due to the mass of data that revolves around us today, a systematic datamanagement system needs to be developed and implemented for organization and quick retrieval of important data. In distance learning systems especially, a large amount of data is communicated and shared between students and educators. Hence, a database is needed for organization of this huge mass of data. Database refers to an organized collection of digital data in a repository and allows users to input, organize, and retrieve data quickly. Database controls redundancy of data, which is prevalent in traditional file systems. It is easier to share files through database and editing can be done by more than one person in a synchronous manner if necessary. Database management system is software that manages the database and the data stored in it. A database management system model describes the protocols for the organization of data in the database and viewing of the data. Examples of database management system models include hierarchical model, network model, object oriented model and relational model (Aznil, 2013). Summary
In this study, a distant education system called VIEW classroom is developed using extensive database technology such as asynchronous interaction support, database views, question-answer database, and database to analyse student achievement. The VIEW classroom system uses these database features for an effective distant teaching and learning process to be possible. Since the system is non-video based, the educator is not able to see the students and discern their academic achievement and learning capability. Hence, a database function is used to store the status of students by symbolic representations on the screen. This reduces the amount of data storage space greatly as compared to video files. Since each student has a different learning capability,...
