I'm having a hard time figuring out how to word this, so picture time.

I have points arranged in a circle, I know the x,y coordinates for all of them.

I can iterate each point and draw a line between them, easy

I'm trying to create a struct that is generic, with a bound that the generic implement a trait. The trait is itself generic. This is in Rust 1.49.0.

If I do this:

I have a product schema in which user(who uploaded ,created the product) is there who creates a product and then there is an order , order schema has the product included , I want it to include the products uploader user . Can anyone help me to do that ? I really hope i make it clear enough it's haunting me for days and I have searched the internet

So, originally I was doing something that was meant to go like this:

I have made a program using python language which tells your Horoscope. I made that on Jupyter-notebook, Anaconda. I opened it on word its code is: {

Have a question that is haunting me for some time.

How in practice looks replacing primary keys with surrogate keys during the ETL process? Like what is the workflow - is it just assigning new IDENTITY? If so, how about previous values, how to replace existing business keys with newly created ones?

In my mind a specific workflow looks like below, but I haven't done it in practice yet:

1. Drop existing PK_Product and FK_Product in DimProduct and FactSales tables.
2. Set a new IDENTITY column to dimProduct.
3. Add new column to FactSales with values from newly created IDENTITY column based on join on previous business key.
4. Drop an old ProductKey columns in both tables.
5. Add constraints for newly created surrogate IDENTITY keys.
6. Assign reference between tables for future-coming values.

But please tell me how you do this in your job and correct me, because I think I'm wrong.

I am quite new in programming and what haunts me about it is not really the coding (well at least not until the present moment!) itself, but some words/concepts that are really important to understand. My doubt is with the word "ABSTRACTION". I have already searched dictionaries and saw some videos of people giving very clear explanations of the word. So, I know that abstraction is when you take into consideration only the things that are important and leave out everything else (putting in very simple and direct language), like for instance, if you are going to change a light bulb, you do not need to know the manufacturer of the light bulb or the light socket. You also do not need to know the materials used to manufacture the light bulb. However, the problem is when you read some texts or listen to people using the word and it does not seem to fit the meaning and then you start to wonder if they misused the word (which I think is very unlikely) or it is because there is another obscure meaning that I have not found yet or maybe it is just because I am too dumb to understand it. Below I put excerpts from articles I was reading and bolded and capitalized the part where the word appears so you guys have a context and understand where my problem is. Thank you.

"A paradigm programming provides and determines the view that the programmer has on the structuring and execution of the programme. For example, in object-oriented programming, programmers MAY ABSTRACT A PROGRAMME AS A COLLECTION OF OBJECTS that interact with each other, while in functional programming, programmers ABSTRACT THE PROGRAMME as a sequence of functions executed in a stacked fashion."

"A tuple space has the function of creating a SHARED MEMORY ABSTRACTION over a distributed system, where everyone can read and write to it."

I have multiple images on my website with some text about each image.

i have these code on my Django
