  Pixel lensing is a technique for searching baryonic components of dark
matter, (MACHOs), in any part of galaxies. This method is very efficient, since
it avoids to resolve each source star and so it has the advantage to provide an
high statistic. Taking into account the fact that this technique is very time
expensive in data analysis phase and the present technology, we propose a new
method to perform a data selection on-line by using two levels of trigger and a
quasi-on-line data analysis. The implementation of the project provides to
obtain soon results since, due to a new database technology, all physical
information are stored for a complementary and secondary analysis to perform
off-line.
