It is the first in a series of talks to explain various aspects of software development in the context of BExIS 2.The idea of this series of talks is to gather the knowledge needed to develop the BEXIS 2 data management platform. So the talks are geared towards software engineers and developers.
The first talk is focused on the general functional and non-functional requirements of a scientific data management system.
