It's pretty good and very, very easy to use.
At first I thought you could connect without SQLNET but this is not true.
It does have multithreading though.
It works very similar to ADO in syntax but returns a cursor like structure
that cannot bind to any grid controls I've seen (there is one made by Oracle
for it..) So you will have to bind it yourself to any grids.

It is well suited to applications that run strictly on Oracle.
