Abstract

A flow preparation assisting apparatus calculates a difference between one or more flow data sets and a template flow data set having been a base of the one or more flow data sets, and calculates a dependency relation between node attributes for a template flow indicated by the template flow data set, from the calculated difference. The flow preparation assisting apparatus issues a notification according to the calculated dependency relation.

Claims

1. A non-transitory computer-readable storage medium storing thereon a computer program for causing a computer to execute:

calculating a difference between one or more flow data sets among one or a plurality of flow data sets generated by one or a plurality of visual programming tools, and a target template flow data set that is a template flow data set having been a base of the one or more flow data sets among one or a plurality of template flow data sets, wherein

each of the one or a plurality of template flow data sets is a data set indicating a template flow represented by a plurality of nodes and a connection between individual nodes in the plurality of nodes,

each of the one or a plurality of flow data sets is a data set indicating a flow represented by a plurality of nodes and a connection between individual nodes in the plurality of nodes, the data set being after editing of a copy of any template flow data set,

each node is associated with one or a plurality of node attributes constituting a property of the node, and

each node attribute is defined by a key and an attribute value;

calculating a dependency relation between attribute values for a template flow indicated by the target template flow data set, from the calculated difference; and

issuing a notification of information on the calculated dependency relation.

2. The non-transitory computer-readable storage medium according to claim 1, wherein

the one or a plurality of template flow data sets are managed by a template management server that is a first server storing the one or a plurality of template flow data sets, and

a relationship between the one or a plurality of template flow data sets and the one or a plurality of flow data sets is managed by a repository management server that is a second server storing the one or a plurality of flow data sets.

3. The non-transitory computer-readable storage medium according to claim 1, wherein

a dependency relation between attribute values is calculated at a time of completion of changing one or more attribute values of one or more nodes in a template flow indicated by a copy of the target template flow data set, and

the notification is issued to a visual programming tool displaying information on a flow data set completed of changing the one or more attribute values.

4. The non-transitory computer-readable storage medium according to claim 1, wherein

calculating a dependency relation between attribute values is, for each attribute value, to calculate a conditional probability that is a probability that, when certain one or more attribute values out of two or more attribute values in the attribute values are changed, another one or more attribute values out of the two or more attribute values are to be changed, and

the notification is a notification of information on one or more attribute values whose conditional probability between one or more attribute values changed with respect to a template flow indicated by a copy of the target template flow data set exceeds a certain value that is preliminary defined.

5. The non-transitory computer-readable storage medium according to claim 1, wherein

editing of a copy of the target template flow data set sometimes includes, instead of or in addition to changing an attribute value of at least one node in a template flow indicated by the target template flow data set, changing at least one of a key corresponding to an attribute value of the at least one node or a node entity of the at least one node, and

in calculation of a difference between the one or more flow data sets and the target template flow data set, even when a part of a node-related element among a plurality of node-related elements such as a key and a node ID, or a node type and a node category is different, attribute values in which the part of the node-related element is different are regarded as mutually corresponding attribute values between the one or more flow data sets and the target template flow data set, as long as a remaining node-related element among the plurality of node-related elements conforms to one or more rules that are preliminary defined.

6. The non-transitory computer-readable storage medium according to claim 5, wherein

one or more tags are associated with at least one key, and

in calculation of a difference between the one or more flow data sets and the target template flow data set, even when at least the part of the node-related element among the plurality of node-related elements is different, attribute values in which the at least the part of the node-related element is different are regarded as mutually corresponding attribute values between the one or more flow data sets and the target template flow data set, as long as one or more associated tags conform to one or more rules that are preliminary defined.

7. The non-transitory computer-readable storage medium according to claim 1, wherein

issuing a notification according to the calculated dependency relation is to issue a notification of information on the calculated dependency relation, to a visual programming tool displaying information on a flow including a node related to the calculated dependency relation, in order to display the calculated dependency relation by the visual programming tool.

8. The non-transitory computer-readable storage medium according to claim 1, wherein

a dependency relation between attribute values is calculated based on a change order of an attribute value for a template flow indicated by the target template flow data set, in addition to the calculated difference for the target template flow data set.

9. A flow preparation assisting apparatus comprising:

a dependency relation calculation unit configured to calculate a difference between one or more flow data sets among one or a plurality of flow data sets generated by one or a plurality of visual programming tools, and a target template flow data set that is a template flow data set having been a base of the one or more flow data sets among one or a plurality of template flow data sets, and calculate a dependency relation between attribute values for a template flow indicated by the target template flow data set, from the calculated difference; and

a dependency relation notification unit configured to issue a notification of information on the calculated dependency relation, wherein

each of the one or a plurality of template flow data sets is a data set indicating a template flow represented by a plurality of nodes and a connection between individual nodes in the plurality of nodes,

each of the one or a plurality of flow data sets is a data set indicating a flow represented by a plurality of nodes and a connection between individual nodes in the plurality of nodes, the data set being after editing of a copy of any template flow data set,

each node is associated with one or a plurality of node attributes constituting a property of the node, and

each node attribute is defined by a key and an attribute value.

10. A flow preparation assisting method comprising:

calculating a difference between one or more flow data sets among one or a plurality of flow data sets generated by one or a plurality of visual programming tools, and a target template flow data set that is a template flow data set having been a base of the one or more flow data sets among one or a plurality of template flow data sets, wherein

each of the one or a plurality of template flow data sets is a data set indicating a template flow represented by a plurality of nodes and a connection between individual nodes in the plurality of nodes,
