Database
A system that organizes and arranges data into fields and provides the means to sort, group, and retrieve information from those fields.  In the library, a database is an electronic index that contains information about articles, books, reference sources, and/or images.  Most databases can be searched by fields like author, title of article and publication, and date.  Some databases cover many disciplines and others cover only one subject area.  For a list of Davidson databases, see the Research Guides.
