Most online databases are accessible through websites. Some require free registration, while others may require institutional access or a subscription. For example, the World Health Organization (WHO) Global Health Observatory provides free access to global health statistics, whereas databases like Scopus may require a subscription. To use these databases effectively, one should be familiar with search techniques and understand how to use filters and keywords to find relevant data. Many databases also offer tutorials and help sections to assist users in navigating their platforms.
