Conventional Path Load
reads in multiple data records and places them in a binary array.
When the array is full, it is passed to Oracle for insertion and Oracle
uses the SQL interface with the array option.
Direct Path Load creates
data blocks that are already in the Oracle database block format.
Blocks are then written directly into the database. This method is
significantly faster, but there are restrictions. For more information
about the SQL*Loader Direct and Conventional Path loads, see your
Oracle utilities documentation for SQL*Loader.
