# Introduction into MDA

MDA2 is a database for hydro dam data, basically. However, it could be used for other data as well. MDA has an intrinsic tree of measure points having time series as its leaves either being imported, being calculated, being manually filled, or being entered into via HWE.

# MDA2 GUI

In the main window, on the top right hand side, you have:

In the main window, on the bottom, you have:

  • You can click on the pane and get an history of the latest messages.
