Meta data is data about data. Power Center 6x / 7x creates
155 / 183 tables, when informatica is installed on an
environment. These tables contains all information of
transaction / changes done in Informatica.
Eg: we can find all the mappings / transformations - last

will usually have the naming convention OPB_.....
These objects / tables are created under schema pointing to
