Computer networks and Internet resources are helping teachers cut down on paper use. Teachers can keep grades and attendance online and use texts that are available at no cost.
Database management systems can be categorized according to the database model that they support, such as relational or XML, the type s of computer they support, such as a server cluster or a mobile phone, the query language s that access the database, such as SQL or X Query, performance trade-offs, such as maximum Paperless library research or maximum speed or others.
This shall support a descriptive examination and multiple clients at a given time. This article describes a novel SQL-based paperless examination system, including objective questions as well as SQL programming questions.
Database, Examination, Paperless, Test, Sql 1. Introduction The paperless examination is a kind of ones that use computer network to replace traditional test paper; some interrelated functions of examination are realized by right of computer simulation.
Paperless examinations play a vital role in the development of modern education in that they effectively reduce teachers grading load and increase their overall efficiency. In addition, paperless examinations reduce errors in grading and promote the fairness of the examination.
Up till now; we have already had a rich class of paperless examination systems. However, those systems concentrate mostly on dealing with objective questions and fall short on more subjective issues such as programming.
There are a few paperless examination systems that orient on programming languages.
Usually, students would have to submit experiment reports and get feedbacks from the teacher who grades the reports. Software Structure The choice of the platform is governed by need of the requirements.
The online exam system requires use of a web based application that can present a descriptive exam format for SQL DML statements. This application requires presenting a highly maintainable, secure platform which provides high robustness, reliable, scalable, and updatable in order to acquire new features in near future to improve user acceptability.
NET is a web application framework developed and marketed by Microsoft to allow programmers to build dynamic web services. Here are the reasons why we should use the MVC design pattern.
When the problems recur, there is no need to invent a new solution. By using the MVC design pattern our application becomes more expressive. The model object knows about all the data that need to be displayed.
It only represents the data of an application. The view represents the presentation of the application. The view object refers to the model. It remains same if there is any modification in the business logic.
The controller is responsible for intercepting the requests from view and passes it to the model for the appropriate action.Explore research at Microsoft, a site featuring the impact of research along with publications, products, downloads, and research careers.
Panel mount recorders are fully integrated data acquisition and display stations with secure, built-in data storage and network connectivity. Panel-mount solutions are NEMA compliant and integrate the data acquisition equipment into a control panel. Paperless Research The New York Public Library subscribes to hundreds of online databases and other information tools.
Some are available onsite while others can be accessed at home using your library card number. Scientific publishing The paperless library.
Free access to scientific results is changing research practices The value of knowledge and the return on the public investment in research depends. Continue reading Paperless Libraries → Public Library, according to the library’s board of trustees, who met on September 17 to listen to community members voice their opinions.
Three members of the local clergy had sent a letter saying some of the books in the display were inappropriate for a public library serving local families.
The most important part of making the decision to go paperless is doing your research so you can decide if the benefits outweigh the challenges. Then, create a systematic process that will not only afford you the benefits of being paperless, but also help improve your productivity at the same time.
