Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
195 words
A data processing network comprising at least one host processor (1, 10, 11) to which is connected a plurality of workstations (2, 4, 6, 8, 12) containing data files (29 to 34) used at the workstations during tasks thereon, the host processor containing a copy of the data files stored at each workstation which may require updating, each workstation being adapted to respond to a query from the host processor by sending a signal to the host processor indicating which data files it is to use for a particular task and the level of those data files, the host processor being adapted to determine from said signal whether that workstation has data files at the latest level, and, if the determination shows that the workstation has a data file or data files at a lower level than the latest level to send a copy at the latest level to the workstation to replace the down-level data file, characterised by the workstations being personal computers, and the data files constituting modules of a personal computer program, each data file including a block (42) of code containing information (43) determinative of the level of the data file.
Claim 2
Dependent Claim
49 words
A data processing network as claimed in claim 1, in which the host processor is adapted to determine which version or release of a data file is stored at the workstation and to send to the workstation only the latest level data file appropriate to that version or release.
Claim 3
Dependent Claim
32 words
A data processing network as claimed in either preceding claim, in which the host processor is further adapted to transmit to the workstation any missing data files required for a particular task.
Claim 4
Dependent Claim
36 words
A data processing network as claimed in any preceding claim, in which the signal from the workstation to the host processor is sent in response to a general query from the host processor to the workstation.
