Benefits of technology

This patented technology allows for efficient testing of complicated documents by generating them with different types of data like image or formula files. It also makes it easier than traditional methods because these tests are designed specifically for specific tasks rather than all things at once. Additionally, this system has an improved ability to mix multiple items together based upon their importance within each item's evaluation area compared to previous systems without any extra effort. Overall, this new approach provides greater efficiency and accuracy during evaluations while ensuring consistently high quality results.

Problems solved by technology

The patent text discusses the importance of examinations in assessing students' knowledge and skills. It mentions that traditional test papers are generated manually, which can be time-consuming and subjective. The text also mentions the limitations of existing online examination systems and automatic test paper generation systems, such as the inability to support elements like images and formulas, and the lack of flexibility in organizing test papers. Based on this information, the technical problems of the patent text can be summarized as follows: 1. The time-consuming and subjective nature of manually generating test papers. 2. The limitations of existing online examination systems and automatic test paper generation systems, such as the inability to support images and formulas, and the lack of flexibility in organizing test papers.

specific Embodiment approach 1

[0058] Specific implementation mode one: the following combination figure 1 This embodiment will be described. A test paper automatic generation device based on BLOB storage and enhanced RichEdit control, including the following modules: user database 1, subject database 2, test question database 3, subject information database 4, system management module 5, BLOB conversion module 6, RTF (Rich Text Format, rich text format) stream import / export module 7, test paper generation module 8, test question modification module 9, test question entry module 10, test question retrieval module 11 and subject information management module 12.

[0059] The user database 1 is a database that stores all user information. User role types include administrators and ordinary teachers. Each ordinary teacher user corresponds to a corresponding examination subject, so that each teacher user can only modify the corresponding subject. test data;

[0060] The subject database 2 stores all subject n...

specific Embodiment approach 2

[0071] Specific implementation mode 2: Combining figure 2 Illustrate this embodiment, use a kind of BLOB storage based on specific embodiment one and strengthen the test paper automatic generation method of RichEdit control, it is realized by the following steps:

[0072] Step a: Read the subject information setting from the subject information database 4, including the total score of each question type of the subject, the assessment ratio of key content and non-key content, etc.;

[0073] Step b: If the extraction of all question types has been completed, go to step e, otherwise go to step c;

[0074] Step c: If the total score of the selected questions of the current question type has reached the preset value, go to step b, otherwise go to step d;

[0075] Step d: Query all test questions that match the current question type in the test question database 3, randomly select from the record set according to the current remaining score, and add the primary key of the drawn te...

specific Embodiment approach 3

[0079] Specific implementation mode three: the following combination image 3 This embodiment will be described. This embodiment is a further limitation of Embodiment 2: the steps for the BLOB conversion module 6 to realize the conversion between the RTF data stream and the BLOB data are:

[0080] Step 1: If saving the test questions, go to step 2; if reading the test questions, go to step 4;

[0081] Step 2: Read the RTF data stream to be stored in binary mode, and at the same time read in the relevant information of the test question;

[0082] Step 3: organize the binary stream read in step 2 and the relevant information of the test questions into a record, insert it into the test question database 3, and go to step 6;

[0083] Step 4: Query relevant records from the test question database 3, and read each field;

[0084] Step 5: restore the BLOB field in the read record to the RTF data stream in binary mode;

[0085] Step 6: Release the database connection and exit the ...

Abstract

The invention relates to an automatic examination paper generating device and method based on binary large object (BLOB) storage and enhanced RichEdit control, which relates to an automatic examination paper generating device based on BLOB storage and enhanced Richedit control, and solves the problems of the existing examination paper generating system that a complex object is not supported, the form and flexibility of examination content are poor, and the formation detail of the examination paper is not complete. The automatic examination paper generating device is characterized in that a user database stores all user information; a subject database stores all subject names; an examination question database stores examination question content and relevant information of each examination question; a subject information database stores relevant information of examination subjects; a system management module provides a system management function; a BLOB conversion module realizes the conversion of rich text format (RTF) data stream and a BLOB; an RTF stream lead-in/lead-out module is used for leading in and leading out the RTF stream; and an examination paper generation module is used for extracting examination questions from the examination question database to generate the examination paper. The device and the method are suitable for automatically generating the examination paper.
