Data Distribution in A Data Processing System

Computer-readable media tangibly embodying a program of instructions executable by at least one computer, the program comprising code to:

• split a first data item into one or more parts;
• for each of the one or more parts of the first data item, determine a corresponding part name, each part name being determined using a message digest function or hash function of all of the data in the corresponding part of the first data item;
• cause each of the one or more parts to be distributed to at least one location in a computer network;
• and
• create a second file, said second file comprising the part names of the one or more parts of the first data item.

A device comprising hardware including at least one processor, and software, in combination with said hardware:

• to split a first data item into one or more parts;
• for each of the one or more parts of the first data item, to determine a corresponding part name, each part name being determined using a message digest function or hash function of all of the data in the corresponding part of the first data item;
• to cause each of the one or more parts to be distributed to at least one location in a computer network;
• and
• to create a second file, said second file comprising the part names of the one or more parts of the first data item.

Computer-readable media tangibly embodying a program of instructions executable by at least one computer, the program comprising code to:

• split a first data item into one or more parts based on a size of the first data item;
• for each of the one or more parts of the first data item, determine a corresponding part name, each part name being determined using a message digest function or hash function of all of the data in the corresponding part of the first data item;
• create a second file, said second file comprising the part names of the one or more parts of the first data item;
• determine a name for the second file;
• associate the name of the second file with the first data item;
• cause each of the one or more parts to be distributed to at least one location in a computer network;
• and
• publish the name of the second file.
