Abstract
A database is an organized and systematized set of connected data saved without unnecessary redundancy. There are three types of databases: bibliographic, quotation and full text databases. Some of the most known databases in the field of biomedicine and natural sciences are: Medline, EMBASE, Web of Science, Cochrane Library. Access for database search is highly individual and almost no single search model exists. Crucial part of the search is using keywords and indexes or subject terms. Keywords make search faster and more accurate. Insufficient search can result in systematic errors in a systematic review and reduce the credibility of results and conclusions. The issue can be unpublished studies, as well as those not listed on the most common search sites like PubMed. The search strategy structure should be based on the main terms that are being examined in the review. Using Boolean logic by using the operator 'AND', 'OR' or 'NOT' and the PICO search strategy gives the best results. If there is a limit for finding specific types of studies (eg. randomized controlled studies), 'filters' can be used to find such studies. General databases such as MEDLINE for Cochrane systematic review include three main conditions: a) terms for searching of a health status of interest, b) conditions for searching intervention, c) conditions for types of studies to be included.
