The so-called thesis is an article that discusses or studies a certain problem. Its extension is an article, and its connotation is discussion and research. Therefore, it is a reasoning article. The emphasis here is on understanding "discussion" and "research", which are the essential attributes of the paper.

Second, the classification:

First, scientific research papers. Is to investigate a problem and write an investigation report; An experimental report written after a scientific experiment on a certain problem; An experience report that summarizes an experience and rises to a higher theoretical level. Their common characteristics are clear research object and clear practice process, which reflect the author's practice and research process. They often make qualitative and quantitative analysis through measurement, statistical data and environmental evidence. If it is studied as a subject, it is a research report.

The second is academic papers. It is a paper that has not experimented or practiced a certain problem, but relies on a certain theory or consulting literature to conceive and explore in theory and put forward strategic thinking. Or a paper that critically thinks about a theoretical problem.

The above two papers are not necessarily completely independent individuals, and there is no completely divided boundary.

The concept of academic papers

Academic paper is an academic style paper that teachers and students in colleges and research institutions often need to write.

Academic papers belong to argumentative style, which can be generally divided into two categories: humanities, social, scientific and technological papers and scientific and technological papers.

Second, the characteristics of academic papers:

(1) academic

The so-called academic nature means that the content of research and discussion is professional and systematic. The specific implementation mode is as follows:

1 The topic of the paper is very professional.

The content of the paper is obviously professional.

3 language terminology.

4. Specialization of the author's literacy.

(2) scientific nature

The so-called scientific nature means that the content of research and discussion is accurate, the thinking is rigorous, and the reasoning is completely logical. The specific implementation mode is as follows:

1

2 scientific research methods

3 scientific content of the paper

The scientific knowledge theory expressed is accurate, structured, rigorous, vivid and solemn.

(3) Creativity

The so-called creativity means that scientific research achievements should be innovative and developed. The specific implementation mode is as follows:

1 New discoveries, new inventions and new theories fill the gaps.

2. Develop, improve and innovate on the basis of inheritance.

Put forward independent opinions among different opinions.

4 overturn the previous conclusion.

5. Creative synthesis of existing data.

(4) Theoretically

The so-called theoretical nature mainly refers to the author's theoretical thinking, theoretical structure and theoretical expression of the paper. The specific implementation mode is as follows:

1 the theoretical nature of thinking.

2 The theoretical nature of the conclusion.

3 theoretical expression. In other words, academic papers are mainly expressed through discussion, and their theory is embodied in the reasoning system composed of concepts and judgments, as well as in various expressions in the process of argumentation.

How to write a good paper

(1) Drawing up an outline

(2) Writing by hands

(3) Modification and retouching

Library management system (computer application paper)

Book management system is a typical information management system (m is), and its development mainly includes the establishment and maintenance of background database and the development of front-end application programs. For the former, it is required to establish a database with strong data consistency and integrity and good data security. For the latter, the application is required to be fully functional and easy to use.

Therefore, according to the requirements of the open library, I have conducted in-depth research and application on MS SQL Server2000 database management system, SQL language principle, Delphi application program design and Delphi database technology, mainly completed the demand analysis, functional module division and database mode analysis of the book management system, and designed the database structure and application program. The running results of the system prove that the book management system designed in this paper can meet the needs of borrowers, librarians and senior managers.

The first chapter briefly introduces the development of database application system and book management system, and analyzes the work that should be done in developing book management system.

The second chapter systematically analyzes the design of database and the use of SQL language, which lays the foundation for a deeper understanding of database application.

The third chapter studies the specific development tool Delphi 6.0, and systematically introduces its database components, the application of SQL language in Delphi and other key database programming technologies.

The fourth chapter analyzes the application requirements of the library management information system, and according to the database design theory, the system requirements specification, local er diagram, global ER diagram, system relationship model and sub-model are given step by step. The database is established by MS SQL Server2000.

The fifth chapter has carried on the concrete program design, specifically divided the operation authority of three types of users, and designed three kinds of operation interfaces. The functions of database table browsing, record addition, deletion and modification, report generation, multi-database table connection operation, multi-condition query and fuzzy query, flexible update operation of unrenewable query result set, master-slave table operation and password maintenance are realized. Finally, the system can also import databases to operate any database with the same structure.

This design makes full use of the powerful functions of Delphi 6 and MS SQL Server2000 database technology, and improves the programming efficiency and reliability.
