Introduction

Databases are systematically organized collections of information covering different subject matters or
specializing in one given subject or topic. They may be arranged in a table of contents, alphabetically,
in numerical order, in an index or in subject categories. A database is made up of records. Each item
in the database has one record. Records consist of smaller units of information called fields. Common
bibliographic database fields are: author, publication title, article title, subject or keywords, publication
date, volume, issue and page number. For example, in the MEDLINE/PubMed database, each journal
citation has one record. The record consists of the following fields: author, article title, journal title,
date of publication, volume, issue, page number, PubMed ID, and abstract. A digital database is a
computer program that organizes, describes, and indexes information. It permits the user to search
for specific types of information, depending upon the selected search parameters.
