CodeIgniter classifieds I need DB sketch - database

I can't image how to create classifieds structure.
Example I have page for cars ads, and there can be fields year, price, and more.
And I have page for mobile phones where can be fields price, color, display size and so on. For another page can be another fields and I need add them dinamicly, it can bee select field, text input, or maybe checkbox.
So how I can add new fields for filtering ads, where to keep form validation rules?
Can someone please give me a sketch of db that can me explain all this process?

Start by sketching simple stuff, like ad title, price etc. Get a paper and list the features you need in a paper, then group them and write the sketch it to paper

How to show more fields on custom object tabs in Salesforce?

Ok so this problem is probably easily solvable, but since I am a beginner in Salesforce and I didn't find anything useful on Google, I am asking if someone can please help me.
So, as you can see, I have created a custom object called Students, and added some fields to it.
Next, I have created a custom object tab, called Student, as you can see on the following image and added some records.
On the custom object tab, only field 'Student Name' is shown. Does anybody know how to display all (or some) of the fields that were added to the object Student?
Thank you so much for your answers and have a great day :)
On the far right of the 2nd screenshot there's a gear/cog icon. Use it for o create new "list view". Or click that "recently viewed", change it to "all" (there should be an auto-generated one for you) and use that gear icon to select which fields to display.
You can even pin the list view to be your default if you don't want "recently viewed".
As for recently viewed itself - it's special, the gear icon won't work. Follow this article: https://help.salesforce.com/s/articleView?id=sf.customize_recent_records_list_lex.htm&type=5

Edit: dynamic forms work on standard objects from Winter'23 onwards.

Not out of the box (yet).
The feature to drop single fields on lightning page layout is called "Dynamic Forms". But it works only for custom objects and Account is standard. Keep an eye on roadmap, next releases, maybe there's idea to upvote...
A developer can create aura or lightning web component with your field, then you'd drop it on that section of the page layout.
If you have VSCode, sfdx configured (bit of upfront investment to set it up but the result will be the bleeding endge of technology SF offers) - look into https://developer.salesforce.com/docs/component-library/bundle/lightning-record-view-form/documentation. If you don't - in a pinch you can work out of developer console to create Aura version of this component (click the button in upper right of that documentation).
This is also a cool working example if documentation is not your thing: https://developer.salesforce.com/docs/component-library/documentation/en/lwc/lwc.data_load_record. Aura version is here: https://developer.salesforce.com/docs/atlas.en-us.lightning.meta/lightning/data_service_load_record.htm

MS Access: Accessing data from multiple tables in a tabbed form

I have an inventory system in MS Access 2010, and am trying to make a form that accesses multiple tables. Here is the relevant part of the data relationships printout:
I have a tabbed form that I am using that, for each food item, allows our orderers to edit/view the food purchasing data for that food item, or edit/view the inventory data for that food item. This is what that looks like:
So, currently, the parent form is using [Food items] as the control source. I want the tabs to basically display (and update when edited) the appropriate data from the [Inventory] and [Food purchase data] tables for that food item. So for instance, in the example above, the Food purchase data tab should be searching for the record for Agave in the [Food purchase data] table, and using that to populate the fields for that tab (and likewise for the inventory tab).
What is the best way to go about this?
Simply, use subforms inside your tabs, maintaining Food Items as the main form's recordsource. Remember, forms are essentially visual representations of tables. So on the main form, build separate forms for Inventory and Food Purchases and then link them just as you do in relationships.
How to specifically integrate subforms on main form?
Build subforms as separate regular forms, either as single, multiple-item, or datasheet. Don't place anything in page header/footer as they will not show on main form. You can use form header/footer.
Then in design view of Food Items main form, go to the tab control and select tab area, making sure yellow outlines appears, then locate the subform/subreport control in menu in Design tab on ribbon (looks like a newspaper icon if you scroll towards the end). Select the form specific to tab.
Walk through wizard, setting up the parent/child linked ids which you can also do on each subform control's Data tab in Property Sheet. Now, form will appear in its own design view where you can stretch out, re-position, and manage its own controls accordingly.

Drupal commerce add text to price

I'm trying to add a simple line off text next to the price in my Drupal Commerce solution.
Seems quite simple but i'm lost where to start. Here is my problem summarised:
Drupal commerce doesn't use templates but views for every page so i want to edit the view
All views contain a rendered entity most off the time a product list
I can add fields to the product list display but these are all fields that are editable on the product page.
So i'm wondering is there a way to add a simple chunk off text (or HTML) to the product list?
Thank you!
