What I want to do: Let's assume that there is article, on Wikipedia, that is under CC-BY-SA license. For exemple "https://en.wikipedia.org/wiki/List_of_pies,_tarts_and_flans". Assume next that I want to get from that article only table that contain list of pies. I want to get only it data (only facts, only copying "words" from the "name", "origin" and "type" columns, but not from "description" column ), without pictures. Let's assume that I want to create pies database using data from this tables. And than I want to build some website, in which user can get "list of random pies". This "random pies" will, of course, be gotten from that database. At one time, user will get only some limited amount of such pies. For example - generating list of 10 pies - by one pressing of button "generate random pies".
What I already found: This type of use, in general, is linked to license on which that article are licensed. This Wikipedia article have license "CC-BY-SA". Also on wikipedia present detailed article on reusing Wikipedia content, where described how to correctly satisfy license terms. So for now I understand that I need to: make attribution, indicate changes, stick "licensing notice" of used article, and also satisfy "Copyleft/Share Alike" part. Please keep this last, "Share Alike", part in mind.
Also license notes from official site: https://creativecommons.org/licenses/by-sa/3.0/
So, here is my question: Trying to satisfy "Copyleft/Share Alike" part: - Am I obligated to make that database of pies publicly available, and with this also license them in the same license? For example, am I obligated to make a button - "download pies database as some file". Or I don't need to do this because I don't share the database directly. I just use some parts of it at once, in not direct way.
What I think about that: Problem is that, that I really need to apply the same license on that database if I will be sharing it publicly. If I made it public. Because this database is "build upon", or is something similar to "adaptation" (https://creativecommons.org/faq/#what-is-an-adaptation), of that table ("ShareAlike — If you remix, transform, or build upon the material, you must distribute your contributions under the same license as the original." (https://creativecommons.org/licenses/by-sa/3.0/)). But I don't know, if giving to users of that site, random parts of that pies database - will this be considered as if database is shared publicly.
And I knew that there was such statement that there no copyrights on information. But there copyrights on databases, and also - is this creation of database will be considered as just use of information, but not other things from used tables.
So my question is merely about "Copyleft/Share Alike" part. Merely about of obligation of making database public.
