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