Using lookup tables - re administrative pages (in my industry updates app)

As explained earlier, my fairly straightforward app will input regularly updating information about an industry (via human keyboarding), into a db that then becomes basis to create weekly reports of the industry updates. Hence, the input side of this app is similar to an administrative backend.

To fill some of the items on an individual input page, lookup tables (in relational-speak) need to be used for all the stock descriptors; they will be used in specifying an industry update (for example, to specify region of the world). In other words, in addition to the table being populated with individual industry updates, there need to be additional tables, static lookup tables, accessible to the page where industry updates are being input.

Of course, this also means on the update insert page there will be dynamic pulldown menus that have been populated from the lookup tables.

To this end.

I have watched the youtube tutorial on using relational tables. An earlier version of DataAssist there, but entirely helpful on an 'include,' I think.

Does the notion of the Insert plug-in, through Framework Builder, still apply here? (To get an 'include,' I think.) But I will not be including a page, only the results from the query into the lookup table. I see Dynamic Plugin there - what do I need to know about its use?

What do I need to know / anything further needed to make this work in my case?

Have also read through the tutorial, Manage relational tables.

Deep down in this tutorial, re the MRT server behavior: Will the machinery accommodate lookup tables, which I believe (uncommonly) share the parent table's Primary key? So only one key, between the two tables.

[CORRECTING my own error, here: Lookup tables do not typically share the Primary key. To note the typical case, subset tables, in a one-to-one relation, share the Primary key with the parent.]

Again, does anything else need to be known in this regard?

Finally, I have not yet identified the tutorials for creating dynamic pulldown menus. May I check where I go to get myself up to date on that?

And best to check, what / where else should I be looking to get arms around this?

Thanks as always, David
