At DESY, writing of the NeXus files is based on NeXus Writer and Configuration Server.
A schematic of the whole process is displayed in Figure 9.4.
The Configuration Server provides configuration string via Control Client into NeXus Writer.
The NeXus configuration is a composition of components and data sources.
The writer fetches the data from the Experimental Control Client, other Tango devices
or various databases and store them into a file system.
