In music, the dominant is the fifth degree of the scale. For example, in the C major scale (white keys on a piano), the dominant is the note G; and the dominant chord uses the notes G, B, and D. In music theory, the dominant chord in its root position is symbolized with the Roman numeral V if major and v if minor.
As defined by Joseph Fetis the dominante was a seventh chord over the first note of a descending perfect fifth in the basse fondamentale or root progression, the common practice period dominant seventh he named the dominante tonique.
"Dominant" also refers to a relationship of musical keys. For example, relative to the key of C major, the key of G major is the dominant. Music which modulates (changes key) often modulates into the dominant. Modulation into the dominant key often creates a sense of increased tension; as opposed to modulation into subdominant (fourth note of the scale), which creates a sense of musical relaxation.

Basically dominantchords are derived from from four different scales: the mixolydian scale, the altered scale, the lydian dominantscale and the half/whole diminished scale.
The following dominantchords are all derived from the G altered scale (Ab melodic minor) The altered scale contains both the lowered and raised fifth plus both the lowered and raised ninth making it an easy scale to apply to dominantchords with altered 5ths.
The chords you get are almost the same except rather than a 7sus chord you'll get a 7#11 chord (guitar players usually play this chord the exact same as we would a 7b5 chord).
An extended tertian chord, however, is often built on scale degree 5 to function as a dominant; 9th and 11th chords may be built on scale degree 2 and serve as a subdominantchord.
Pre-Dominant Chords: are chords that precede the dominant (or sometimes the tonic six-four and then the dominant) in a cadence.
Secondary Dominant (7th) of V: is a major triad or a major-minor 7th chord built on scale degree 2 (with scale degree 4 chromatically altered to #4).
