A Different formulations of QFT

    As far as I understand now, there are at least three different formulations of QFT:

    1) Second Quantization
    2) Functional Formulation(where there is wave-functional which is a function of the field configuration and satisfies a functional Schrodinger equation)
    3) Path Integral

    Is there any other formulation out there?

    Also, I know that QFT textbooks usually treat QED using second quantization and then turn to path integrals for non-abelian gauge theories(except for Bailin and Love that uses path integrals throughout). But the only textbook I know that spends some time on the functional formulation is Hatfield. Is there any other textbook that develops the functional formulation and uses it to calculate any physical quantity?

    Thanks
