What is a database? A database is a collection of data or information that is organized, stored, and accessed electronically. There are three main well-defined aspects of any database:
It is relevant (相关的). When searching for information in the database, you should be able to get results relevant to you. There are several ways to search through a database, for example, using keywords, subject headings, terminology (术语), etc.
One of the main differences between the information you find on the internet and that in databases is that the information found in databases is often confirmed. Furthermore, the information in the database should have key identifiers such as the publication (发表）details, author's name, and a summary that you can use to confirm the information.
It is accessible. First of all, access to the library is either free or bought by supporters so that you can access the information within it at no price. Secondly, the database should provide the full-text of the articles, meaning you will not need to go to the library or the source to do so.
It is an academic search engine. It doesn't always have the articles' full texts, and you may have to go to their libraries and find or pay for them. Also, the search engine collects seemingly academic information from the internet and some of this information isn't always confirmed.
A. It is reliable.
B. It is reasonable.
C. You may have to pay a small amount of money as an independent researcher.
D. Google Scholar isn't a database using the above three aspects as a determining factor.
E. It is organized so that searching and finding this information is easy and rapid.
F. They are all relevant factors to be referred to when searching educational databases.
G. So you can limit your search results to a certain source type or date, or you can search by author or title.
