Contextual Types of Databases
Databases provide various formats of information. Different databases
provide different kinds of information. Text, graphics and audio
information grouped by what they have in common.
Bibliographic databases provide a descriptive record of an item,
but the item itself is not provided in the database. Information
about the item is provided, including such things as author, title,
subject, publisher, etc. The information provided is called a citation.
Sometimes a short summary or abstract of the item is provided as
well. Examples - GALILEO database and the Internet Movie .
Full Text Database
A full-text database provides the full-text of a publication.
For instance, Research Library in GALILEO provides not only the
citation to a journal article, but often the entire text of the
article as well. Another example is “CollegeSource Online",
which offers full-text of 20,000 college catalogs, providing students
with the ability to compare several colleges rather than having
to request a catalog from each college.
Numeric databases provide information, such as statistics or demographic
information. Examples - The Census Bureau databases and databases
containing stock market information.
Multimedia databases contain only images, [EBSCOhost image collection],
audio information [MP3] and video [.wav] files, or a combination
of any of the above types. An example is CNN's site search giving
access to news articles and the original video and audio files that
Meta-databases are databases that allow one to search for content
that is indexed by other databases.
