A guide to data repositories and repository search engines is established, and its main characteristics are explained. The importance of the role of journals in the process of sharing research data, international trends in scientific journals, and the levels of access to research data sets, are explained. The advantages of the application of data sharing and its importance are discussed.

Conclusions:
