A database is a collection of information resources (journal articles, books, book chapters etc) organised so it can be easily searched, accessed, managed and updated.
Databases help you to find high quality, up-to-date journal articles that have been published by respected publishers and publications.
If you have been asked to find scholarly articles for your assignment, you will need to search the library catalogue or more importantly, a database!

Ei Village provides access to both INSPEC and Compendex. You can search both databases simultaneously to find citations with abstracts (with links) in physics, electronics and electrical engineering, and computer fields. Primary coverage is of journal articles and conference papers, plus significant books, technical reports, and dissertations. Chemical and process engineering, computers and data processing, electronics and communication, civil engineering and mechanical engineering areas are also covered.
Databases in other engineering subject guides may also be useful.
