Description

A method for automatically drawing the topological structure diagram of university course offering relationship

technical field

The invention relates to the field of computer software development, in particular to a method for automatically drawing a topological structure diagram of a university course offering relationship.

Background technique

The topological structure diagram of the course offering relationship is a common graph that intuitively reflects the talent training program of colleges and universities, and it is an important task that colleges and universities must complete when formulating undergraduate talent training programs for various majors. At present, such topology diagrams are generally drawn manually in Visio or other tool software, which is extremely inefficient; when drawing, all courses offered in the talent training plan need to be sorted one by one according to the semester, the platform, and the nature of the course. Layout to an appropriate position, and then draw a connection line expressing the sequence of courses according to the prerequisite courses and follow-up courses listed in the syllabus of each course. In this process, whether it is the addition/modification of each course, the acquisition/adjustment of the course offering sequence, and the drawing/adjustment of relationship connections, it is very time-consuming and labor-intensive, and the relationship expression is complex and error-prone. So far, no software or algorithm has been found in the software that has been released to the public that can automatically draw the topological structure diagram of the course offering relationship; for this purpose, a method for automatically drawing the topological structure graph of the course offering relationship in colleges and universities is provided.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a method for automatically drawing a topological structure diagram of a university course offering relationship in view of the defects of the prior art, so as to solve the problems raised by the above-mentioned background technology.

In order to achieve the above purpose, the present invention provides the following technical solutions: a method for automatically drawing a topological structure diagram of a university course offering relationship, the specific steps are as follows:

S1: Obtain the course information offered by the major and the course offering relationship information, and save the information into the database of the course offering topology diagram drawing module;

S11: When drawing the topological structure diagram of the major for the first time, obtain the detailed information of the courses offered by the major from the training target materials of the major, and add all the course information into the "Course Opening Data Table";

S12: According to all the courses offered by the major, check the corresponding course syllabus one by one, and store the course and the successor courses of the course into the "course opening relationship data table" one by one, and all the successor courses are conducted in English ";" separate;

S2: Obtain the professional course opening information and course opening relationship information from the database into the algorithm;

S21: Query the database according to the professional number and grade number, and save the returned results in an array;

S22: The multiple successor courses of the course offering relationship are separated by Chinese ";" in the database. After the program is obtained, each successor course is divided into an array separately;

S3: further initialize the acquired professional course opening information array;

S31: The course opening status of the major is displayed on the page in the form of a table with 4 rows and 8 columns. The 4 rows correspond to the 4 course attribution platforms, and the 8 columns represent the 8 semesters.

S32: Count the number of courses in the semester with the most courses among the 4 attribution platforms, and then add supplementary arrays* in other semesters of the same attribution platform, so that the number of the same attribution platform is the same in each semester;

S4: Display the professional course offerings on the page; traverse the array of course offerings, and put them into the corresponding 4-row 8-column table according to the course's attribution platform and the starting semester. The supplementary array is also placed but it will be Hidden, exists on the front-end page, but is not visible;

S5: Adjust the position of the course; the course can only be adjusted in its current attribution platform and in the form of the starting semester, and an algorithm is designed to adjust the position of the course by clicking on the course to adjust the course to the appropriate one. position to ensure that it is easy enough to draw lines;

S6: Draw the opening relationship line according to the course opening relationship array; because the position of the course in the topology map needs to be adjusted according to the needs, so to draw the line after the course position is determined, it is necessary to generate an html page first, showing all the opening conditions, Then draw lines on this basis, that is, to draw lines between DOM elements. Here, the svg line drawing method encapsulated by the component Leader-line is used to draw lines between DOM elements.

As a preferred technical solution of the present invention, in S11, the detailed information of the courses offered by the major is obtained from the training target materials of the major, and the detailed information includes the semester for which the course is offered and the platform to which the course belongs.

As a preferred technical solution of the present invention, in S11, all course information is added into the "course opening data table", and the opening semesters are stored in the data table as numbers: 1-8 respectively represent the 8 semesters of the university, the courses The attribution of the platform is stored as numbers in the data table: 1-4; 1 represents the general education platform, 2 represents the professional education platform, 3 represents the professional education platform, and 4 represents the practical course education platform.

As a preferred technical solution of the present invention, in the step S12, the course and the subsequent courses of the course are stored in the "course opening relationship data table" one by one. Considering that the course syllabus may not be fully compiled, this method will not obtain the In the case of the course offering relationship, add manual management to add, delete, modify and check the course offering.
