There are two general types of databases. A multi-publisher database, like ProQuest Central, which contains journal articles from many publishers. The journal types can be peer reviewed, trade or popular. In these databases there is generally a limit to peer-reviewed journals. In a publisher database, like Emerald, the journal titles are only those published by the publisher. These are generally peer-reviewed journal titles and so there is no limit needed. Scopus is a little different as it is a citation database, having no full text, and only indexes/lists peer-reviewed journal titles. It does have scientific web sources and conferences as well. Again, it does not need a peer-reviewed limit.
If you are unsure if a journal title is peer reviewed, check the journal title using the ulrichsweb.com database. The following webpage explains the differences in journal types, includes a link to ulrichsweb.com and a brief video explaining its use: Finding Academic Journals.
