UTL_FILE:
The Package UTL_FILE permits your PL/SQL programs to read & write operating system (OS) text files. It gives a restricted version of the standard OS stream file I/O, involving the open, put, get, and close operations. When you desire to read or write a text file, you call the function fopen that returns a file handle for use in consequent procedure calls. For illustration, the procedure put_line writes a text string and line terminator to an open file. The procedure get_line reads a line of the text from an open file into an output buffer.
The PL/SQL file I/O is accessible on both the client and server sides. Though, on the server side, the file access is constrained to those directories explicitly listed in the accessible directories list that is stored in the Oracle initialization file.
UTL_HTTP:
The Package UTL_HTTP permits your PL/SQL programs to make hypertext transfer protocol (HTTP) callouts. It can recover data from the Internet or call Oracle Web Server cartridges. The package has 2 entry points, each of that accepts a uniform resource locator (URL) string, links the specified site, and returns the requested data, that is usually in the hypertext markup language (HTML) format.
