A database is a collection of data systematically stored so that they are easy to retrieve.
One example of a database is the Library catalogue, which contains information about the library’s books and makes it possible to find a particular book quickly.
There are different kinds of databases for different purposes, and in this chapter you can read about how they work and in what contexts they are useful. The structure of a database, and the search facilities offered, differ greatly depending on what type of material the database covers.
Searching for information in databases is different from using Internet search engines. In the Search guide section there are many great tips on how you can make better and more effective database searches, see for example the texts about search terms and search technique.
Many databases are freely available on the Internet like the Library catalogue, but some are commercial and subject to a charge. Students and staff at Blekinge Institute of Technology have access to a number of databases which the Library subscribes to. When you use a computer on campus you automatically have access to all information resources. In the text Searching from home in the Search guide section you can read more about how to access the Library’s information resources from home.
