Abstract
Abstract A distributed processing system that has a host and at least one connected work station. Each information object requested by the work station from the host is stored at the work station and is retained according to a predetermined hierarchy of priorities. When the work station initiates a request for an information object, the work station storage is first interrogated for the object and it is obtained therefrom if present. Only if the object is not in work station storage, is a request then transmitted to the host to obtain the information object.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
121 words
A data processing system having: (a) a host processor, (b) a work station connected to said host processor, (c) means connected to said host processor for inputting data objects to said host processor, (d) host processor means responsive to requests from said work station for transmitting requested ones of said data objects to said work station, (e) work station storage means responsive to receipt at said work station of said requested ones of said data objects for storing said requested ones of said data objects at said work station, and (f) means at said work station for establishing retention priorities in said work station storage means for said requested ones of said data objects according to a predetermined order of retention.
Claim 2
Dependent Claim
121 words
A data processing system having: (a) a host processor, (b) a work station connected to said host processor, (c) means connected to said host processor for inputting data objects to said host processor, (d) host processor means responsive to requests from said work station for transmitting requested ones of said data objects to said work station, (e) work station storage means responsive to receipt at said work station of said requested ones of said data objects for storing said requested ones of said data objects at said work station, and (f) means at said work station for establishing retention priorities in said work station storage means for said requested ones of said data objects according to a predetermined order of retention.
Claim 3
Dependent Claim
26 words
The data processing system according to claim 1 in which said host processor includes host storage means for storing said data objects at said host processor.
Claim 4
Dependent Claim
22 words
The data processing system according to claim 1 in which said host processor includes host storage means for storing said data objects.
Claim 5
Dependent Claim
30 words
The data processing system according to claim 1 in which said predetermined order of retention comprises ascribing to the most recently received data object a highest level of retention priority.
Claim 6
Dependent Claim
31 words
The data processing system according to claim 1 in which said predetermined order of retention comprises ascribing to the most recently used data object a predetermined upper level of retention priority.
Claim 7
Dependent Claim
45 words
The data processing system according to claim 1 in which said predetermined order of retention comprises ascribing to the most recently received data object a highest level of retention priority and to the most recently used data object a predetermined upper level of retention priority.
Claim 8
Dependent Claim
26 words
The data processing system according to claim 6 further including means for ascribing to the most remotely used data object a lowest level of retention priority.
Claim 9
Dependent Claim
40 words
The data processing system according to claim 1 further including means at said work station effective when a requested data object is not stored within said work station storage means for requesting said requested data object from said host processor.
