Question

1.人类已进入21世纪,科学技术突飞猛进,经济知识和信息产业初见端倪,特别是信息技术和网络技术的讯速发展和广泛应用,对社会的政治,经济,军事,文化等领域产生越来越深刻.学生成绩管理系统是一个教育单位不可缺少的部分,它的内容对于学校的决策者和管理者来说都至关重要.
成绩管理是学校的一项重要工作，原有的人工管理存在这着很多不足，造成不足的原因是，在校学生人数众多，并且每个学生的信息过于复杂，从而工作量非常大，给统计和查询带来了不便。因此，如何解决这些不足，使成绩管理更快捷、更方便，具有更高的效率也就成了一个关键问题。
随着科学技术的迅速发展学校成绩管理的自动化也越来越迫切，因此有必要开发成绩学籍的软件系统来辅助学校的教学管理。本系统是一个学生课程和成绩管理系统，它是高校教务管理系统中的一个子系统。主要用户是学生、教师和管理员。系统方便了学生选课和查分。方便了教师的教学管理和学生成绩的录入。更为重要的是，系统方便了学校的教务管理。
2.人类已进入21世纪,科学技术突飞猛进,经济知识和信息产业初见端倪,特别是信息技术和网络技术的讯速发展和广泛应用,对社会的政治,经济,军事,文化等领域产生越来越深刻的影响,也正在改变人们的工作,生活学习,交流方式.信息的获取,处理,交流和应用能力,已经成为人们最重要的能力之一.
在不久的将来知识经济将占世界经济发展的主导地位,国家综合国力和国际竞争能力越来越取决于教育发展,科学技术和知识创新的水平,教育在经济和社会发展过程中将呈现出越来越突出的重要作用.学生成绩管理系统是一个教育单位不可缺少的部分,它的内容对于学校的决策者和管理者来说都至关重要,所以学生成绩管理系统应该能够为用户提供充足的信息和快捷的查询手段.但是一直以来人们使用传统人工的方式管理学生成绩,填写各种表格,这种管理方式存在着许多缺点,如:效率低,保密性差,另外所用其时间长,产生大量的文件和数据,这对于查找,更新和维护都带来了不少的困难.
随着中国加入WTO,意味着我国要在同一个网络平台上参与国际竞争,同世界接轨.这对我们既是一个机遇,也是一个挑战.为此我们必须全面加强全民的信息技术教育,以提高我国的整体素质.科学技术的不断发展和提高,计算机科学技术日渐成熟,其强大的功能人们已有深刻认识,它已进入人类社会的各个领域并发挥着越来越重要的作用.
作为计算机应用的一部分,使用计算机对学生成绩管理系统进行信息管理,有着手工管理所无法比拟的优点,如:检索迅速,查找方便,可靠性高,存储量大,保密性好,寿命长,成本低等.这些优点能够极大地提高学生成绩系统管理的效率,也是教育单位的科学化,正规化管理,与世界接轨的重要条件,因此,开发一套这样成绩管理软件成为很有必要的事情.

Answer 1

1. Mankind has entered the 21st century, science and technology, economic knowledge and information industry has seen an initial clue, especially in information technology and network technology very rapidly and the development and wide application of social politics, economy, military, cultural and other fields have more To the more profound. Student performance management system is a unit of education an essential part of it for the content of school administrators and policy makers is crucial.
Performance management of the school is an important task, the original artificial management with a lot less than this, resulting in inadequate because of the large number of students, and each student's information was too complicated, so the workload is very large, the Census and Statistics For inquiries, and has brought inconvenience. As a result, how to resolve these deficiencies, so that the performance management faster, more convenient and more efficient has become a key issue.
With the rapid development of science and technology school management automation increasingly urgent, there is a need to develop school performance software system to support the classroom teaching management. The present system is a curriculum and student performance management system, it is the Educational Management System in a sub-system. The main users are students, teachers and administrators. System to facilitate the selection of students and check points. The convenience of teachers and pupils of entry. More importantly, the school system to facilitate the management of the Senate.
2. Mankind has entered the 21st century, science and technology, economic knowledge and information industry has seen an initial clue, especially in information technology and network technology very rapidly and the development and wide application of social politics, economy, military, cultural and other fields have more To the more profound effects are also changing the way people work, study and life, the way the exchange.'s Access to information, treatment, communication and application capabilities, it has become one of the most important ability.
Knowledge-based economy in the near future world economic development will account for the dominant position of the country's overall national strength and international competitiveness increasingly depends on the development of education, science and technology innovation and knowledge level of education in economic and social development process has shown more To highlight the more important role. Student performance management system is a unit of education an essential part of it for the content of school administrators and policy makers is crucial, the performance management system so students should be able to provide adequate Information and efficient means of inquiry. But it has been using the traditional manual management of the academic performance of their students fill in a variety of forms, such a management style there are many shortcomings, such as: low efficiency, poor privacy, and used his for a long time and have a large number of Documents and data, which is to find, update and maintain all bring a lot of difficulties.
With China's accession to the WTO, our country means to the same network platform to participate in international competition, with the world. This is not only an opportunity for us, but also a challenge. So we need to strengthen education for all information technology to improve our country The overall quality. Science and technology development and the advancement of computer science and technology is reaching maturity and its powerful people have a deep understanding that it has entered the human society in various fields and is playing an increasingly important role.
As part of the computer application, the use of computers for student performance management system for information management, management manual has unmatched advantages, such as: quick search, looking for convenient, high reliability and large capacity storage, security and good, long life, cost Low. These advantages can greatly improve student performance management system, the efficiency of the education unit is more scientific and standardized management, integration with the world's important, therefore, to develop a set of performance management software has become such a necessary thing.
