Best Method for Storing Course Materials for Exam Question Generation

I want to make a program that generates exam questions. This program generates questions based on course materials. Data is composed of multiple texts with parent-child relationships, similar to a tree structure. Requirements for the question: 'I first select a subtext, then the program searches for the parent text of this subtext, and then randomly searches for another 3 subtexts under this parent text. Finally, I combine the subtext I selected with the other 3 subtexts found, as the 4 options of the multiple-choice question.'

Right now I have 2 ways to store the course material for question making. One of the ways is to use JSON to store text. Because the parent text (parent key) of the subtext (child key) in JSON cannot be obtained directly. Therefore, only the upper layer of the subtext in JSON can be traversed, and the parent text containing the specified subtext can be queried. Then operate according to the requirements of the question.

The second method is to use HTML to store text. Because HTML has a tree structure, you can directly query the parent text (parent tag) of the child text (child tag). But if you want to make the course materials have a tree structure, you can only use HTML nesting. I can only think of nesting using multiple pairs of

Which method should I choose for storing course materials for questioning?

It ultimately depends on the specific requirements and constraints of your program. Here are some factors to consider:

1. Complexity: If your course materials are relatively simple and do not require complex formatting, using JSON may be the simpler option. On the other hand, if your materials require more advanced formatting, such as images, videos, or interactive elements, HTML may be necessary.

2. Querying: Consider how you will need to search and retrieve specific pieces of information from your course materials. If you will frequently need to find parent-child relationships, HTML may be the more efficient option. However, if you can structure your JSON data in a way that allows for easy querying, that may be a better choice.

3. Scalability: Think about how your program will grow and evolve over time. If you anticipate adding more complex course materials in the future, it may be better to choose HTML to allow for greater flexibility.

4. Familiarity: Consider your own experience and expertise with each option. If you are more comfortable working with JSON, that may be the better choice for you, even if HTML could potentially offer more benefits.

Ultimately, the decision of which method to choose should be based on a careful evaluation of your program's needs and constraints, as well as your own experience and preferences.
