  We review in detail the Hamiltonian dynamics for constrained systems.
Emphasis is put on the total Hamiltonian system rather than on the extended
Hamiltonian system. We provide a systematic analysis of (global and local)
symmetries in total Hamiltonian systems. In particular, in analogue to total
Hamiltonians, we introduce the notion of total Noether charges. Grassmannian
degrees of freedom are also addressed in details.
