The digital contents database requires a more complexes software tools in order to searching, analysis’s, compression and reproduction. Wavelet theory provides the fast discrete algorithms suitable to computer programming application. The clear mathematical theory is a good base to creating a programs environment and a number programs packages. The wavelet transform application are thinking less without a programming software package but the most used are WaveLab, LastWave, MegaWave i Rice Wavelet Toolbox. Because the mentioned software products belong to free ware software category, it is possible to use that with registration legality. The answer on the questions is given in the paper: which wavelets, which models, which programs, which date sets are giving the best results.
