Preface:
About the teaching plan part is the scope I should think, here I will determine my own thinking ideas and derive your analysis results according to this idea.
Analytical method:
I think the method of analysis should be the entity that seizes the teaching plan part, the entity should include data (can be understood as an attribute), including the operation of the entity itself. After analyzing a clear particle size, simple entity, analysis is established between the operations and association between these entities and entities, in fact, the correlation between the entities and the actual relationship, and interconnected operations, can also be carried out according to the impact Decomposition and finishing, analyzing the operating unit equivalent to particle size. In this way, we can basically clearly use the same entities, business elements to assemble our business.
Basic entities that can be extracted:
The basic entities that can be extracted in the teaching plan are: level, professional, grade (entry batch), copies of teaching programs, courses, teaching programs, courses (under teaching plan), graduation conditions (graduation conditions under teaching programs) ), The type of student status (also known as learning type), semester. These entities have a standard increase, modification, delete, and browse.
Association between basic entities:
The association relationship between these entities is described below:
1: The relationship between teaching programs and levels, professional, and learning. A teaching plan corresponds to a level, professional, a student status type, and a teaching plan can only correspond to a group of hierarchical and professional, subject types, and a combination of schools. The same set of combinations cannot correspond to multiple teaching programs.
2: Course and teaching programs, the relationship between courses resources. A teaching plan can have multiple courses resources, and the curriculum resources after the teaching plan are called a course. There is a lot of relationships between courses resources and teaching programs, but the same curriculum resource cannot be associated with the same teaching plan.
3: The relationship between graduation conditions and teaching programs. A teaching plan corresponds to a graduation condition. This two entities are currently a standard one-on-one relationship, but from the perspective of analysis, multiple teaching programs can appear for a course of graduation conditions.
4: The relationship between semester and courses. One semester can correspond to multiple courses (courses under teaching programs), and a course cannot correspond to multiple semesters.
Below is the basic relationship between these basic entities above:
5: Copy and course resources, teaching programs, courses. A copy of a teaching plan is included, and all of the latest issues, teaching programs, and courses existing when creating a copy, but does not contain hierarchical, professional. Below is an entity diagram of a copy of the teaching plan.
6: The relationship between the grade (batch) and the level, professional, and teaching programs. The grade corresponds to multiple levels, professional, teaching programs, and courses. Here are the relationship between batch and basic entities.
The two relationships of the 5 and 6 described above are actually a solution for two parallel teaching plan management and maintenance. Regarding the copy of the teaching plan, you can refer to the description in the "Teaching Plan Deputy Solutions". For the sixth relationship, it is actually the management method of the batch teaching plan, that is, each new batch, new year enrollment needs to recreate a teaching plan, the so-called new teaching plan. That is to include hierarchical, professional, batches, and teaching programs.
Here we focus on analyzing them together and different points. Through the relationship, we can clearly distinguish between the two solutions or understand the difference between the two relationships. In the "Copy Plan" of the Teaching Plan, there is only the curriculum resources and teaching programs included in the teaching plan. Under the batch teaching plan, the batch teaching plan includes hierarchical, professional, teaching programs, and courses. The only thing in the two programs here is that both teaching plans and courses are included, and the course resource information is not included in the batch plan. All batch teaching programs contain the same course resources, and the professional information is only batch. The teaching plan is included, and the copy scheme is not included. Through this analysis, it can be clearly discovered. No matter how to manage teaching programs, it is inevitable that the teaching plan itself, and the courses he include must be independent, so it is based on future effective management. However, different points and clear explanation have the essence of the two programs. The copy scheme is a set of overall programs that contain all changes. Although the teaching plan and course information are completely independent of different copies, he always wants Following the overall teaching changes, all changes must change according to the business development, so under the copy scheme, there is no need to independence record level, professional, all copies of information is unified, this program is the most It is reflected that all teaching activities change is a continuous predictable process, which can clearly understand what the current results and what changes have, which can be clearly judged after the changes will be affected. More concerned about the batch teaching plan is a clear structure of unpredictable changes in the future, and the structure of independent hierarchies is clearly shown that allowed customers to be based on the new batch of teaching structures and directions. It is not necessary to consider the characteristics of continuous teaching, nor does it provide sustainable tracking and prediction, because this program potential sense is that it is impossible to predict what will happen in the future, so it is necessary to establish all of the level, professional, teaching programs, and courses.
