Actually, you can capture SQLs relatively inexpensively by using FGA - simply add the "audit_condition => '1=1'" when adding a policy to each table.
For OLTP, this wouldn't make much sense. For ad-hoc (DSS), what you are going to do with all those captured SQLs is another story.
For statistics, logon & logoff triggers + v$mystat + autonomous transactions. If you want to capture all sql, it will be hard & very resource hungry, you either enable trace for given session (which slows stuff down enormously) or poll v$sql or v$open_cursor frequently. This isn't a good idea either. You might want to look at fine grained auditing if you want to track which data is viewed by anybody.
