Wavelet tree is recursively built applying decomposition and approximation filter only to the (father wavelet) approximation filter output at each step (or level). Wavelt packets, instead, are constructed by applying both filters to approximation and decomposition filter output resulting in a 2^(n+1)+1 nodes with respect to 2(n+1)+1 nodes of standard discrete wavelet tree
With Daubechies you can use practical subband coding scheme. You don't have to no the actual wavelet and scaling functions, but rather you need to know low-pass and high-pass filters related to a certain Daubechies wavelet family.
Convolution in the time domain is equivalent to multiplication in the frequency domain.

It is a domain testing for checking the errors, like software testing. It is used for the debugging purposes based on the telecommunication. You can register with a secured domain name from the trusted websites like tucktail
in wavelet transform only approximate coeffitients are further decoposed into uniform frequency subbands while in that of wavelet packet transform both approximate and detailed coeffitients are deomposed further into sub bands.
Fourier transform analyzes signals in the frequency domain, representing the signal as a sum of sinusoidal functions. Wavelet transform decomposes signals into different frequency components using wavelet functions that are localized in time and frequency, allowing for analysis of both high and low frequencies simultaneously. Wavelet transform is more suitable than Fourier transform for analyzing non-stationary signals with localized features.

It allows you to store the information of a signal in a small number of coefficients.
