The image is a whiteboard with a list of notes written in French. The notes are written in blue ink and are arranged in a neat and organized manner. The title of the notes is written in large, bold letters at the top of the whiteboard. Below the title, there is a diagram that appears to be a flowchart or flowchart that explains the different types of data flow diagrams and their meanings. 

The flowchart is divided into several sections, each with a different type of text and a brief description of the data flow. The first section is labeled "A l'aise" which translates to "A level" in English. The second section is titled "Anonymat" which is a type of mathematical equation. The third section is labelled "me mas intérieur" which means "me has interpreted" in French, and the fourth section is described as "me is interpreted". The fifth section is highlighted in blue, indicating that it is the first step in the flowchart.

There are also several other notes written on the board, including "On a les 2" and "Technique" which are likely related to the concept of data analysis. The background of the image is white, and there is another whiteboard on the right side of the board.
