What is a database?
Answer
A selected collection of information, organized into records. Each record may contain information, or can point to another resource that contains the information, like a journal article or a web page. For example, in the UpToDate database, each record contains information on a specific medical topic; in the PubMed database each record contains a citation and an abstract that directs you to a specific health sciences journal article; the Google database contains records that point you to specific web pages on the open web.
