How to connect / build reports against data integration schema?

Summary:

In Data Exchange, after loading we need to get some statistics on numer of records exported, sum/avg of these records, etc.
In EPM Integration Agent documentation we've found it's possible to build reports against data integration schema, see https://docs.oracle.com/en/cloud/saas/enterprise-performance-management-common/diepm/appendix_tables.html

How can we connect to that schema? Is there a url, user, password? Is it possible to query TDATASEG Table for example?
