This webinar aimed to introduce social science researchers to the basic principles of data management, including the creation of a Data management plan, which is an important tool for planning the research project. The webinar consisted of three parts. The first part will introduce researchers to the basic principles of data management including the benefits of adopting Data Management Plans (DMPs). The DMP follows the research project’s life cycle, starting with the initial phases of Planning and Organization, and documentation of research data. This part also included a presentation of best practices for the creation of the appropriate structure of folders and data files, as well as instructions for their naming, documentation and organization. The second part of the webinar focused on the following three phases of the project life cycle: Data processing, Preservation and Protection. Contemporary social science presumes the respect of high level ethical standards during the handling of research data, in accordance with legal rules and best practices in this area. The last part of the webinar was dedicated to the phases of Publication - familiarizing the researchers with the possibilities of data preservation and publishing as well as Data discovery - discussing the ways and means to acquire social science data, including the secondary use of data produced by other researchers.
