The present invention relates to integration workflows, and more particularly to handling branches in workflows.
Integration tools are used to connect multiple Software as a Service (SaaS) systems in an integration workflow. Within these workflows, the term ‘node’ is used to describe a step in the workflow. Often, these nodes refer to interaction points with the external SaaS systems. Integration tools also often contain logic enabling the integration flow to diverge along different branched paths depending on predetermined conditions.
It is known to implement a schema when the different branch paths converge, providing a mechanism for downstream nodes to reference the output of a node on a branch. The implemented schema requires manually defining an output schema at convergence points and then manually defining the mappings to this output schema on each branch.
For more complex data flows, where the number of branches and the number of nodes on each branch can dramatically increase, this schema implementation becomes more and more time-consuming and unwieldy for a user.
According to an aspect of the present invention there is a computer-implemented method for automatic generation of convergent data mappings for branches in an integration workflow, comprising: generating a branch schema for each branch, wherein the branch schema represents the union of all the individual node output schemas on the branch; generating a common output schema for a convergence point, wherein the common output schema represents an intersection of all the branch schemas; and generating branch mappings from each branch node to the common output schema.
According to another aspect of the present invention there is a system for automatic generation of convergent data mappings for branches in an integration workflow, comprising: a processor and a memory configured to provide computer program instructions to the processor to execute the function of the components: a branch schema component for generating a branch schema for each branch, wherein the branch schema represents the union of all the individual node output schemas on the branch; a common output schema component for generating a common output schema for a convergence point, wherein the common output schema represents an intersection of all the branch schemas; and a branch mapping component for generating branch mappings from each branch node to the common output schema.
According to a further aspect of the present invention there is a computer program product for automatic generation of convergent data mappings for branches in an integration workflow, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to: generate a branch schema for each branch, wherein the branch schema represents the union of all the individual node output schemas on the branch; generate a common output schema for a convergence point, wherein the common output schema represents an intersection of all the branch schemas; and generate branch mappings from each branch node to the common output schema.
The computer readable storage medium may be a non-transitory computer readable storage medium and the computer readable program code may be executable by a processing circuit.
The invention, both as to organization and method of operation, together with objects, features, and advantages thereof, may best be understood by reference to the following detailed description when read with the accompanying drawings.
Preferred embodiments of the present invention will now be described, by way of example only, with reference to the following drawings in which:
It will be appreciated that for simplicity and clarity of illustration, elements shown in the figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements may be exaggerated relative to other elements for clarity. Further, where considered appropriate, reference numbers may be repeated among the figures to indicate corresponding or analogous features.
Embodiments of the present invention enable automatic generation of convergent data mappings for branches in an integration workflow by generating a common output schema for all branches and suggesting high-confidence mappings for each branch. A common output schema is generated for a convergence point and mappings are generated from output fields in each branch to the common output schema.

Embodiments of the present invention may generate 101 a branch schema for each branch, where the branch schema comprises output fields from one or more nodes in the branch. The branch schema represents the union of all the individual node output schemas on the branch, wherein the branch schema comprises one or more the output fields of the individual node output schemas on the branch.
Branch schema generation may comprise generalizing output field properties in the branch schema for output fields in more than one node including modifying the field type definition to comprise equivalent fields across different nodes.
Embodiments of the present invention may compare 102 the common output fields of the branch schemas to determine related fields. Comparing the common output fields of the branch schemas may comprise applying a measure of similarity of the fields (such as a confidence measure) and discarding fields below a threshold similarity. A confidence map may be generated between fields in different schemas.
Embodiments of the present invention may then generate 103 a single common output schema formed of the related output fields. The common output schema represents an intersection of all the branch schemas to define an output schema at a convergence point. An intersection of all the branch schemas means an equivalent field must be in each of the branch schemas to be comprised in the common output schema.
Embodiments of the present invention may generate 104 mappings for each branch to the common output schema. Each branch will use the same common output schema, but each branch may individually have different mappings applied based on the upstream nodes in its respective branch. Those mappings are applied at the end of the branch at the convergence point.
Embodiments of the present invention automatically selects and creates unified field attributes, which provides an advantage in terms of time and a decrease of cognitive load on the user. Embodiments of the present invention generates a common output schema where the input is multiple branch schemas. By only creating one common output schema, a performance benefit is expected as opposed to running sequentially through chains of mappings.
The mapping carried out in embodiments of the present invention may be carried out by an existing mapping component of integration flow systems. Mapping components are known to use a pre-trained Artificial Intelligence (AI) algorithm which uses Natural Language Processing schema matching to find the closest match between source and target mappings. The algorithm assigns a percentage of confidence to each mapping suggestion based on semantic proximity to a target field, using business object metadata such as the field name, description, and display name to find the correct match. This means that the mapping component also facilitates mapping fields from custom objects and schemas where there are no field naming standards.
Such a known mapping component may be applied to provide a confidence map when comparing common fields of the branch schemas. A confidence map may provide a percentage of how well the common fields match. The mapping component may also be used to generate the branch mappings to the output schema.
For generating a confidence map, two or more schemas may be selected to be compared and matched. Each schema contains all available information and metadata about the node from where it was sourced and its fields. The following properties for each field detailed in the schema may be used as inputs to compare and gain confidence values:
Algorithms may be used for each comparison step such as natural language processing. An overall confidence value may be derived for each field comparison and if it meets a minimum value threshold it is added to a list of suggestions. The list of suggestions may then be sorted into a descending order, with the highest value typically being the one selected, or suggested first for the user.
The described method provides a key user experience differentiator in integration products by increasing speed and efficiency on user tasks over existing solutions. This reduces the cognitive load on the user as they do not have to work with many different output schemas.

Embodiments of the present invention may iterate through all branches. For each branch, embodiments of the present invention iterates through the nodes in the branch, and for each node, embodiments of the present invention iterates through the output fields in each node, where a field property is a part of the output schema of each node. Once there are no output fields in a node, embodiments of the present invention iterates to a next node. Once there are no more nodes in a branch, embodiments of the present invention iterates to a next branch.
Embodiments of the present invention may start 201 and a first branch 202 is considered and an initial empty branch schema is created 203. Embodiments of the present invention considers 204 a first node in the branch and considers 205 a first output field in the node. For this output field, embodiments of the present invention determines 206 if the branch already contains this property. If it does not already contain this property, the output field is added 207 to the branch schema. If it already contains this property, embodiments of the present invention determines 208 if the type definition is the same. If it is not the same, the type definition is modified 209 to comprise the new type. Embodiments of the present invention then loops to consider 205 if there is a next output field in the node and embodiments of the present invention iterates for each additional output field.
Once consider 205 determines that there are no more output fields in the node, embodiments of the present invention loops to consider 204 if there is a next node in the branch. If there is a next node in the branch, embodiments of the present invention iterates through all the output fields in that node.
Once consider 204 determines that there are no more nodes in the branch, embodiments of the present invention loops to 202 to consider if there is a next branch. If there is a next branch, embodiments of the present invention creates 203 an initial empty branch schema for the next branch and embodiments of the present invention iterates through all the nodes in this branch and through all the fields in each node.
Once it is determined that there are not more branches, embodiments of the present invention results in branch schemas for each branch and goes to the flow of

The smallest branch schema is selected as the branch schema with the least number of output fields and embodiments of the present invention iterates 221 through each output field of the smallest branch schema.
A first output field in the smallest branch schema is considered 222 and it is determined 223 if the output field is related to at least one other output field in all the other branch schemas. If it is not so related, embodiments of the present invention loops to determine 222 if there is a next output field in the smallest branch schema.
If the output field is related to at least one other output field in all the other branch schemas, embodiments of the present invention may determine 224 if the related output fields also share a relationship with each other. This may comprise determining a confidence level of the relationship and applying a threshold confidence level below which it is determined that a relationship does not exist or is not sufficiently strong.
If it is determined 224 that a relationship does not exist or is not sufficiently strong, embodiments of the present invention may loop to determine 222 if there is a next output field in the smallest branch schema. If it is determined 224 that a relationship does exist, a field definition is added 225 to the output schema. Again, embodiments of the present invention loops to determine 222 if there is a next output field in the smallest branch schema.
Once there are no more output fields to consider in the smallest branch schema, the output schema is complete and embodiments of the present invention may generate 226 mappings from individual nodes of the branch to the output schema.

A simplified System1 lead may have a schema of the following form:
Similarly, a simplified System2 lead may have a schema of the following form:
The properties that have been singled out are similar, but not exactly the same. First, embodiments of the present invention may generate branch schemas, referred to as schema A and schema B. As there is only one node on each branch, each branch schema is equivalent to the single node on its branch. So the schema for branch A is equivalent to the System1 schema, and the schema for branch B is equivalent to the System2 schema.
A mapping component is leveraged to assist in generating a schema which is an intersection of all the branch schemas, in this case the schema for branch A and the schema for branch B. For each output field in the schema for branch A, the mapping component is used to assess how related each output field in the schema for branch B is. A sample output might look like the following:
Any field below a preconfigured threshold is discarded. For example, with a threshold of 0.8, leaving:
Fields can only be considered as intersections if they intersect with the same fields in all other branches.
For two branches, this is relatively trivial. Embodiments of the present invention may simply need to check that A.fieldA is related to B.fieldB. The inverse (B.fieldB is related to A.fieldA) is true by default.
For three branches, embodiments of the present invention may check if A.fieldA is related to B.fieldB, A.fieldA is related to C.fieldC, and B.fieldB is related to C.fieldC, and so on.
In the example, A.LastName and B.lastName is an intersection. This process is repeated for all fields in A and B, until all the intersecting fields have been calculated.
This leaves a final common output schema of:
Finally, for each branch, the mapping component is used to automatically generate mappings to the output schema.
So for Branch A:
and for Branch B:
Although this is a simplified example using two branches and two schemas, it should be clear that this can be arbitrarily extended to any number of branches and nodes.

Cloud Computing
It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.
