Abstract: A data delivery system uses a database containing a plurality of contents that can be delivered to the client devices at the requests of a client. Conventionally, data is “owned” by a user, that is, users have their own copies for the data. Such a method requires a large amount of, yet unnecessary, storage space. It is especially true when different users own the same data. A conventional technique, called reference counting, is used in programming where one memory data structure can be shared by multiple processes or other client data structures. Reference counting systems perform automatic memory management by keeping a count in each memory object of how many references there are to the object. Objects to which there are no references may be reclaimed. The reference count is incremented for each new reference, and is decremented if a reference is overwritten, or if the referring object is recycled. If a reference count falls to zero, then the object is no longer required and can be recycled.
