Oracle Tips by Burleson 

Direct Load

Direct load is Oracle feature designed to implement faster loading of large data quantities.  During the direct load, SQL is bypassed, the client pre-formats Oracle blocks and Oracle's database writer process, popular DBWR, writes the block to the disk.  This usually results in shorter path through Oracle code, bypassing the SQL engine and making extremely fast writes, thus shortening the load time drastically. In newer versions of Oracle, the client library also known as OCI library  has that capability. If  C/C++ bindings are used, one can write an application utilizing the direct load capability. PHP5 does not implement this feature of OCI library. That, however, doesn’t prevent scripts from using  the /*+ APPEND */ hint in insert statements. Same as with the array interface, this feature is not very useful for the web applications.
