Db Major 7, written Dbmaj7, is built from Db, F, Ab and C: the root, major 3rd, 5th and major 7th.
Its 3rd and 7th, F and C, are its guide tones: they say what kind of chord it is, so voicings are built around them and the root is often left to the bass.
In the progressions here, Dbmaj7 is the Imaj7 of the Major ii-V-I Progression in Db, the IVmaj7 of the Minor Plagal Cadence in Ab, the ♭IIImaj7 of the Tadd Dameron Turnaround in Bb and the ♭VImaj7 of the Coltrane Changes in F.
