What is a database and what is a journal?
A "database" is a large collection of information, often including multiple journals, where you can search for articles across various sources on a specific topic, while a "journal" is a single publication that regularly publishes articles focused on a particular subject area, essentially acting as a container for individual research papers within a specific field; think of a database as a library shelf holding many different journals, each with its own collection of articles on a specific topic.
