This is the tuning
D2-A2-D3-G3-D4-A4 tuning (for a children's 53 cm scale length guitar)
It is a 3-courses bouzouki D2-A2-D3 and an interval of 4 higher a 3-curses tambouras or sazi G3-D4-A4.
Because the intermediate 3 strings A2-D3-G3 are of equal intervals of 4 apart, it allows for ordinary major and minor chord triads with easy dominant and major 7nths.
The consecutive strings with in between intervals 5-5- allow also for 2-3 frets major-minor triads.
Notice that the 4-strings D2-A2-D3-G3 is already an inverted high-low pitch Irish bouzouki tuning
The inverse order Tambouras- bouzouki is also possible e.g.
D2-A2-E3-A3-E4-A4 but because there are not consecutive intervals of 4 or 4 it does not allow for
1 or 2 frets triads.
For the oud and for a standard 66 cm scale length guitar one tone lower is more appropriate
C2-G2-C3-F3-C4-G4
The above tuning seems to be one with the almost maximum number of strings an interval of 5 apart which also allows for easy 1 or 2 frets major-minor triads
THE LATER TUNING ALLOWS TO PLAY IN MELODIES THE PARTS OF THE MELODIC THEMES OF INTERVALS OF 2 OR 3 HORIZONTALLY WHILE SΗIFT THE MELODIC THEME BY INTERVALS OF 4, 5 OR 8 VERTICALLY. IN TOTAL I FIND THIS TUNING VERY CONVENIENT FOR MELODIES IMPROVISATION.
