+    - a user account can hold several projects
+- Projects
+    - Projects group data that belongs to one simulation
+    - Data is also available after the simulation is finished
+    - individual data stream, sets of data streams or the whole project data can be downloaded as CSV files or package of CSV files
+- Plot one or more data streams against time in real time
