This Util gives you a high level fingerprint of a Oracle DB schema. 

Hopefully people will find this Util useful when comparing Oracle environments, (between dev, test, prod) and when upgrading stacks to make sure environment control is in place and environments are like for like.

It runs the following SQL against the supplied details

Description       - SQL
Oracle Version    - "select * from v$version"
Number of Tables  - "SELECT COUNT(TABLE_NAME) FROM ALL_TABLES"
Number of Columns - "select count(column_name) from all_tab_columns"
Number of Indexes - "select count(index_name) from all_indexes"
Number of Views   - "select count(view_name) from all_views"
DB Character Set  - "select value from nls_database_parameters where parameter='NLS_CHARACTERSET'"

then displays the details on a single line. 

EXAMPLE OUTPUT:-
