Literature review is one of the pillars on which your research idea stands since it provides context, relevance, and background to the research problem you are exploring.
A literature review should begin with a thorough literature search using the main keywords in relevant online databases such as Google Scholar, Pub Med, etc.
Once all the relevant literature has been gathered, it should be organized as follows: A literature review should not be a mere recounting of all the available information.
The study therefore provides strengthened results that are validated by the scientific rigor of the analytical method.
Before starting to write a review, it is important to determine what kind of review you want to write and follow the appropriate style and guidelines.
