The concept of "conceptual data model of the subject area". How to understand this?
I'm writing my thesis. When defending a thesis, you also need a presentation. To the requirements of this presentation, I see that the presentation should include a description of the "conceptual domain data model" .
My thesis is on pattern recognition. Namely, handwriting recognition. There is a program that is trained to recognize handwritten letters. The input is a picture with letters and the algorithm produces recognition. Different algorithms are used. But what should I include in the description of the conceptual domain data model in my case? I don't quite understand what this concept means. What does it actually need to describe?
