When we conducting literature reviews, what indicators that predict the resources we collecting data is acceptable? Plenty examples uses database like PubMed, etc. How do we know that the database is good enough? Please give me advice. Thank you.
Sources like PubMed which are literature aggregators are fine for acquiring a sense of what is out there, but only by reviewing specific articles and following up with/on researchers of interest to you, comparing their findings to your own work, will you know which avenues to pursue. Using reputable texts in the field of choice to identify specific researchers is also useful (they had to cull the literature). You have to critically evaluate each piece of literature to determine if it is a defensible thesis/methodology to determine weight of evidence. PubMed and other sources are fine for your first cut.
I would say the most important element in a literature review is diversity of resources. Show your examiners/tutors that you are not frightened of readings views that opposed your own wherever you can find them.
The literature review should be divided into primary and secondary first. Each segment should be then explored in a multi-dimensional way. Also try to understand if the Wh questions can be answered as related to your research.
Search reputable databases, such as Pubmed, Sciencedirect, MDPI, BMC, Bentham, Springer, etc.
Scopus and Web of Science are good databases to start with for any research topic and literature review. Scopus is a large multidisciplinary database covering published material in the humanities and sciences. It also provides citation analysis of authors and subject areas.

I normally use MDPI papers which are current and majority are open access and have high impact factor.
