Answer / srinidhi koushik

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
modified time / last successful run time etc. These tables
will usually have the naming convention OPB_.....

These objects / tables are created under schema pointing to
the database connection hich is provided when Power center
is installed
