What is true of it

D♭7 is D♭, F, A♭ and C♭ — 1, 3, 5 and b7 counted from D♭.

On an instrument that cannot reach all 4, the 5 goes first, in that order.

The easiest of the 5 fingerings below is x112: 2 fingers, one of them barring the 1st fret, held at the 1st fret.

None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.

1 of the 5 need a barre.

It leaves out the 5. 4 strings cannot carry 4 notes, and the 5 is the one this chord can lose without changing what it is.

1 string stays silent.

The brass dots are D♭, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
