3.0 Theoretical Framework
Theoretical framework is a group of related ideas that provides guidance to a research project or business endeavor. IT narrows the research question and helps researchers create hypothesis and assumption.
The proposed system will compose several concepts. Distance learning, Implementing, portal and database. These concepts will be discussed.
3.1 Distance Learning
Distance learning is a way of learning remotely without being in regular face-to-face contact with a teacher in the classroom. In the UK such learning has its roots in students learning through correspondence courses.
In synchronous learning, all participants are present at the same time. In this regard, it resembles traditional classroom teaching methods despite the participants being located remotely. It requires a timetable to be organized. Web conferencing, videoconferencing, educational television, instructional television are examples of synchronous technology, as are direct-broadcast satellite (DBS), internet radio, live streaming, telephone, and web-based VoIP distance learning usually means students engaging with learning materials at home or work.
• These materials are produced by the university, college or learning provider and are either sent directly to the student or more usually today accessed via the internet.
• Tutorial support is provided via a virtual learning environment, telephone, email or other electronic means.
• There may be occasional face-to-face encounters with tutors and attendance at week-long summer schools.
3.2 Implementing portal
Portal (e-portal) is a single gateway through which to gain access to all the information, data, systems, and processes used by stakeholders of an organization. Stakeholders of an organization may include employees, customers, investors, or business partners (suppliers, distributors, resellers, agents, franchisees and so on). The user’s experience of the e-portal is uniquely tailored to his or her individual needs, and the user can access the e-portal via the corporate intranet (typically employees only), extranets, or the Internet.
Benefits of implementing a portal
• Improved customer and business partner loyalty
• Full understanding of new web visitor information
• Improved employee communications and productivity with enhanced business processes
• Improved levels of customer interaction with an increase in customer service
A database is a collection of information organized to provide efficient retrieval. Database, also called electronic database, any collection of data, or information, that is specially organized for rapid search and retrieval by a computer. Databases are structured to facilitate the storage, retrieval, modification, and deletion of data in conjunction with various data-processing operations
A database is stored as a file or a set of files on magnetic disk or tape, optical disk, or some other secondary storage device. The information in these files may be broken down into records, each of which consists of one or more fields. Fields are the basic units of data storage, and each field typically contains information pertaining to one aspect or attribute of the entity described by the database. Records are also organized into tables that include information about relationships between its various fields. Although database is applied loosely to any collection of information in computer files, a database in the strict sense provides cross-referencing capabilities. Using keywords and various sorting commands, users can rapidly search, rearrange, group, and select the fields in many records to retrieve or create reports on particular aggregates of data.
