How so? A DB schema is not visual: it's something that lives inside a DBMS. Boxes with arrows is a way to represent it. Text is another one.


>A DB schema is not visual

How is it not visual?

>Boxes with arrows is a way to represent it. Text is another one.

Boxes with arrows are clearly visual. The text, at least, for me just is a representation of those arrows and boxes.


> How is it not visual?

Perhaps it is. But then you should be able to answer: where is that visualization on disk? And I don't mean the encoding thereof, I mean the actual 2D picture you could glance at and immediately recognize. Not rendered with some image viewing program, but literally looking at the disk/SSD (perhaps under a microscope, if necessary) -- that should be doable, because you're claiming that schemas are inherently visual, and certainly that schema exists on disk somewhere, which in turn implies that those boxes and arrows should be visible on the storage medium.

> Boxes with arrows are clearly visual.

You've changed the topic -- no one is saying that boxes and arrows are not clearly visual. Where are those boxes and arrows sketched into an SSD or in memory? Or, would you assert that a database is schema-less until someone draws up a diagram?

The boxes and arrows image representation of a schema is not the schema itself. See also: https://en.wikipedia.org/wiki/Map%E2%80%93territory_relation


> How is it not visual?

(not the person you're responding to) It's not an image. It's a concept. I don't know how to explain the difference because I also only know it from the explanations of my partner. For example, she says that if she imagines a house it looks like a schematic drawing of a house (almost like if a child would draw a house), not like a realistic photograph of a house.


I'm pretty sure everybody (for certain values of "everybody") visualizes things as schemata; being able to imagine only specific, known, real examples instead of representative composites is a feature of autism. But here it sounds more like you're talking about a highly symbolic/abstracted example of a house vs. a highly detailed/concrete example of a house (rather than the autistic "actual house I have actually seen before"). I don't see how any of these wouldn't still be considered visual mental imagery and I'm starting to think that the people saying there's a semantics issue here might have a point.


When I 'visualize' it's not an image at all. It's the concept of what the image would be showing, which the above posters have called a graph or schematic. But that's an analogy, and not to be taken too literally. I don't visualize a schematic. I instead feel the connections and relationships between concepts. It's entirely non-visual.


I see, it sounded like you were saying you were visualizing a schema[1] (not schematic) of a house but thought it didn't qualify as visualization for some reason.

Does it feel like this is unsymbolized[2] or taking the form of a different mental imagery? (Mental "imagery" can be "visual imagery", or aural, tactile, kinesthetic...)

(Second link is my own re-re-posted comments about the subjective experience of "unsymbolized thought" and doesn't reflect some newer understanding on my end about it -- chiefly, the understanding of unsymbolized thoughts as similar to the aborted motor commands seen in subvocalizing, for example, except aborted much earlier; this explains why it would be difficult to continue doing it if I don't keep it moving along, since each "unsymbolized thought", or thought-granule or what have you, is already the beginning of a process that necessarily leads to some form of mental imagery and corresponding aborted motor command)
