I've built out a logical standby database before with the help of a team mate so I never fully understood the concept of the logical vs physical standby. What are the main differences? When building one out what are the different steps? I remeber there was a step to convert from logical to physical but entirely sure.

THANKS!

The main difference is that a physical standby is a block for block copy of the primary database.  Changes are applied at the block level.  Logical standby is a copy of the data from the primary.  Changes are applied by running equivalent SQL statements.

johnsone has stated it quite well.

I just wanted to offer up the doc link.  The online docs typically have everything you need:
