Abstract

A method for storing and retrieving electronically transmitted data through the use of distributed indices. Data to be stored is received and automatically stored and indexed on the basis of information contained within the data. Similarly, requests to retrieve data are received and automatically routed to the proper storage location on the basis of information contained within the data. The data to be retrieved is then compiled and automatically transmitted to the user. High speed search and retrieval of the data is possible by using different data fields to divide indices to the data into small functional groups and distributing these groups on processors and storage media relevant to the data'"'"'s storage location. This index distribution ensures that individual indices retain a small memory size and directs the search to a particular processor, thus decreasing the time required to retrieve stored information. The storage and retrieval method has the ability to receive, examine and transfer data transmissions into storage with a minimum amount of material or labor, the ability to automatically create an index keyed to certain data fields, the ability to manipulate the index such that retrieval times are held constant independent of the volume of stored data, and the ability to automatically transmit requested data to a user.

Claims

1. A method for storing data containing:

(1) a plurality of fields including a data identification field and a field containing additional information, and (2) a user designation, comprising;

upon receipt of the data, examining the data identification field and the user designation, and on the basis of these two items of information alone, selecting a unique and predetermined item or set of items of media on which the data will be stored; and

storing the data on that unique item or set of items of media.

2. The method of claim 1 including the additional step of creating an index and storing that index on the unique item or set of items of media, the index being used to locate the stored data within the unique item or set of items of media.

3. The method of claim 1 wherein the unique item or set of items of media is one or more optical disks.

6. The method of claim 1 wherein the method is performed by a storage/retrieval processor system.

8. The method of claim 1 wherein the user designation is an electronic mail address extension.

4. A method for retrieving stored data containing:

(1) a plurality of fields including a data identification field and a field containing additional information, and (2) a user designation, comprising;

based upon the data identification field and the user designation, selecting a unique and predetermined item or set of items of media on which the data to be retrieved has been stored;

locating within the selected item or set of items of media the stored data; and

retrieving the stored data from the selected item or items of media.

5. The method of claim 4 wherein the selected item or items of media contain an index providing the location of the stored data within the selected item or items of media, and that index is used to locate the stored data within the item or items of media.

7. The method of claim 4 wherein the method is performed by a storage/retrieval processor system.

9. The method of claim 4 wherein the user designation is an electronic mail address extension.
