Thanks for replying ifor the litretaure review as a collecting refrences and reading articles through is it good ? Or can we make a schematic diagram with it ? With my respect
Yes, qualitative software programs such as NVivo are frequently used in constructing literature reviews. In that case, each item in the literature review its treated as a document and and you can apply codes, just as you would with any text document. But NVivo would be expensive for this purpose, so you might take a look at either Mendeley or Zotero.
NVivo can create a schematic diagram that links any set of coded texts, but if all you want is a "concept map," then there are any number of free programs that will do that.
