Archive und Forschungsdaten – sechs Kernfragen aus Sicht der Archive

Klindworth, Elisabeth 27 May 2022 (has links)
Im Zuge einer zunehmend digital ausgerichteten Forschung werden Fragen der langfristigen Sicherung und Nachnutzung von Forschungsdaten immer wichtiger, insbesondere auch im Kontext des Aufbaus einer Nationalen Forschungsdateninfrastruktur (NFDI). Archive sind fest etablierte Akteure der Forschungsinfrastruktur und verfügen bereits über langjährige Erfahrung in der Datenarchivierung. Im Online-Forum zum Thema 'Archive und Forschungsdaten' wird untersucht, wie der Begriff 'Forschungsdaten' in den Archiven verstanden wird. Darauf aufbauend werden Handlungsfelder für Archive identifiziert und die Rolle der Archive in der Forschungsdatenmanagement-Community diskutiert. Ein Austausch und eine partnerschaftliche Zusammenarbeit mit allen Akteuren in der Forschungsdatenlandschaft werden dabei angestrebt, damit effiziente und pragmatische Lösungen für die langfristige Nutzbarkeit von Forschungsdaten etabliert werden können. / In the course of increasingly digitally oriented research, questions of long-term preservation and subsequent use of research data are becoming more and more important, especially in the context of establishing a National Research Data Infrastructure (NFDI). Archives are firmly established players in the research infrastructure and already have many years of experience in data archiving. The online forum on 'Archives and Research Data' examines how the term 'research data' is understood in the archives. Based on this, fields of action for archives are identified and the role of archives in the research data management community is discussed. The aim is to exchange information and cooperate in a spirit of partnership with all stakeholders in the research data landscape so that efficient and pragmatic solutions for the long-term usability of research data can be established.

A comparison between MongoDB & CouchDB on search performance : A comparative analysis

Kinnander, Mathias January 2018 (has links)
When storing and handling Big Data sets a database management system (DBMS) can be implemented to administrate and query databases. The Swedish Internet is a big unstructured data set that contains all published Swedish Websites since the late 1990’s. NoSQL DBMSs such as MongoDB and CouchDB are particularly suited to store the Swedish Internet. Comparing the search performance of MongoDB and CouchDB in this scenario required the insertion of a subset of the Swedish Internet, querying of the data and measuring the search performance. The results show that CouchDB has in general a superior performance but comes with a drawback which is its indexation time. If a query will only be executed a few amount of times MongoDB is generally the better choice. Further studies needs to be conducted in order to assess the performance of NoSQL DBMSs over the whole dataset.
