RE: Database Metrics

I use these two to show the number of tables created and tables modified by month. In our case, the number of new tables and DDLs has been climbing as the database is getting more complex. On a graph, the lines are climbing upward which is something management can understand.

select TO_CHAR(Created, 'YYYYMM') "MonthCreated", Count(TO_CHAR(Created, 'YYYYMM')) "TablesCreated" from dba_objects
where object_type = 'TABLE'
group by TO_CHAR(Created, 'YYYYMM')
order by 1;

select TO_CHAR(LAST_DDL_TIME, 'YYYYMM') "MonthModified", Count(TO_CHAR(LAST_DDL_TIME, 'YYYYMM')) "Tables DDL'ed" from dba_objects
where object_type = 'TABLE'
group by TO_CHAR(LAST_DDL_TIME, 'YYYYMM') order by 1;
