What is a Database?

A database is a collection of related data that can be retrieved through searching.

Databases can be bibliographic, namely they can either contain only bibliographic facts (i.e. author, title, volume, publication date) as well as abstracts or provide access to the full text of the article. For further information please refer to the General Guide to Bibliographic Databases. It must be noted that only members of the academic community of the H.O.U. are given access to bibliographic databases through the username and password credentials they have been supplied, for logging in the Educational Portal of the H.O.U.
