In addition, in one or more embodiments, specific features, structures, or characteristics can be combined by any suitable manner from the present disclosure which is clear to those skilled in the art.

[0036] In visual process orchestration, a variable is an element for storing and managing data, which can be passed and used between different parts of an application. A process orchestration system usually includes a variable subsystem, which is a subsystem for managing information of variables and accessibility of variables in the process orchestration system. Due to the need for accessibility control of variables in the variable subsystem, there are technical problems of high complexity and high development and maintenance cost.

[0037] The present disclosure provides a technical solution, which can realize the accessibility control of variables in the process orchestration process and reduce the development and maintenance cost of the variable subsystem in the process orchestration system.

[0038] FIG. 1 is a flowchart illustrating a variable processing method for a process orchestration procedure according to some embodiments of the present disclosure.

[0039] As shown in FIG. 1, the variable processing method for the process orchestration procedure includes: step S10, creating a storage space corresponding to each process node for a plurality of process nodes set in a process orchestration interface; step S20, storing a variable defined on each process node in the storage space corresponding to each process node; and step S30, in response to an operation for obtaining a variable accessible by any process node, obtaining a variable in a storage space corresponding to a first process node having a first association relationship with the any process node as a variable accessible by the any process node for display in the process orchestration interface.

[0040] For example, each step in the variable processing method is packaged in the form of a pre-written code library in an SDK (Software Development Kit), helping developers of the process orchestration system to more easily develop a variable subsystem. In some embodiments, the SDK can be deployed in the variable processing apparatus. The SDK is only a packaging method for a code library, and those skilled in the art can also package the code library in other ways to provide it for use in programming by developers.

[0041] In the above embodiments, each process node corresponds to a storage space that can store a variable defined on the process node, and a variable accessible by any process node can be obtained from the storage space of a first process node having a first association relationship with the any process node for display, that is, based on the association relationship between the plurality of process nodes, the accessibility control of the variable in the process orchestration procedure is realized, and by providing a mechanism for obtaining a variable accessible by any process node, the development of the variable subsystem is more easily realized in the development process of the process orchestration system, the cost of developing and maintaining the variable subsystem by the process orchestration business is reduced, the process orchestration business is more quickly implemented in the variable subsystem, a high expansion mechanism is provided for the variable subsystem, and any type of visual process orchestration business can quickly implement the development of the process orchestration system, and the accessibility control of the variable is realized.

[0042] The process orchestration interface of the process orchestration system mentioned in the present disclosure may, for example, provide a fixed layout process orchestration service or a free layout process orchestration service.

[0043] FIG. 2A is a schematic diagram of a process orchestration interface in a fixed layout scenario according to some embodiments of the present disclosure.

[0044] As shown in FIG. 2A, in the fixed layout process orchestration, the process orchestration user can add the process node 2 by clicking the adding control (shown by "+" in FIG. 2A) between the process node 1 and the process node 3.

[0045] FIG. 2B is a schematic diagram illustrating a process orchestration interface in a free layout scenario, according to some embodiments of the present disclosure.

[0046] As shown in FIG. 2B, in the free layout process orchestration, the process orchestration user can drag the process node in the area 1 to the area 2. Referring to FIG. 2B, the process orchestration user drags the process node 1 and the process node 2 in the area 1 to the area 2. Further, the process orchestration user connects the process node 1 and the process node 2 by the connection line with the arrow direction, to represent that the process node 1 is executed before the process node 2.

[0047] The above-mentioned FIG. 2A and FIG. 2B are only as an example to help understand the technical solution of the present application, and do not specifically limit the scheme of the present disclosure.

[0048] No matter in the fixed layout scenario or the free layout scenario, the process orchestration user can define the variable on each process node. The storage space corresponding to each process node for storing the variable defined on the each process node can be any form of storage space, and the present disclosure does not specifically limit this.

[0049] The variable processing method of the present disclosure will be described in detail below in combination with other embodiments.

[0050] FIG. 3 is a flow schematic diagram illustrating a variable processing method, according to some embodiments of the present disclosure. The difference between FIG. 3 and FIG. 1 is that FIG. 3 illustrates the step S40 of the variable processing method in the embodiments of the present disclosure.

[0051] As shown in FIG. 3, the variable processing method includes the steps S10-S40.

[0052] In the step S10, for a plurality of process nodes set in the process orchestration interface, a storage space corresponding to each process node is created. The plurality of process nodes include the any process node and the first process node. The first process node can be one or more.

[0053] The steps in the variable processing method are packaged in the form of a pre-written code library in the SDK, for example, the operation of creating a storage space corresponding to each process node is represented as a function or interface for creating a storage space exposed to developers by the SDK. During the development of the process orchestration system, the developer can call the function or interface for creating a storage space in the variable processing method by coding, so that the process orchestration system can call the function or interface for creating a storage space to create a storage space corresponding to the process node set by the process orchestration personnel when the process orchestration personnel sets the process node in the process orchestration interface.

[0054] In step S20, the variable defined on each process node is stored in the storage space corresponding to each process node.

[0055] In some embodiments, storing the variable defined on each process node includes storing the variable defined on each process node in a tree data structure, wherein the tree data structure includes at least one tree node, each tree node stores one variable, and in the case where the tree data structure includes multiple tree nodes, the multiple tree nodes include a parent node and a child node, and the variable stored by the parent node has a hierarchical relationship with the variable stored by the child node. In this embodiment, storing the variable defined on each process node in a tree data structure can achieve the storage of variable hierarchical information, and is easier to develop and maintain the variable subsystem in the process orchestration system and is easy to expand.

[0056] For example, the hierarchical relationship includes a relationship in which the variable stored by the parent node contains the variable stored by the child node. An example of implementing the containing relationship between variables using a tree data structure can be referred to FIG. 4.

[0057] FIG. 4 is a schematic diagram of a tree data structure according to some embodiments of the present disclosure.

[0058] As shown in FIG. 4, the tree data structure includes tree nodes 1-5. The tree nodes 1-5 store variables 1-5, for example. The tree node 1 is the parent node of the tree nodes 2 and 3. The variable 1 stored by the tree node 1 contains the variable 2 stored by the tree node 2 and the variable 3 stored by the tree node 3. The tree node 3 is the parent node of the tree nodes 4 and 5. The variable 3 stored by the tree node 3 contains the variable 4 stored by the tree node 4 and the variable 5 stored by the tree node 5.

[0059] In some embodiments, the tree data structure comprises an Abstract Syntax Tree (AST), and each tree node is an AST node. The AST is usually used to represent the syntax structure of the code in a programming language. The AST supports the operation of various tools and libraries. The disclosure adopts the Abstract Syntax Tree to store the variables defined on each flow node to realize the storage of variable level information, which can simplify the work of code analysis and conversion, and further reduce the cost of flow orchestration business development and maintenance of variable subsystem.

[0060] Taking the case of packaging each step in the variable processing method in the form of a pre-written code library in an SDK, the background of the flow orchestration system developed by the developer receives the data of the variables defined by the flow orchestration personnel on each flow node from the front end, and combines these data into multiple AST nodes to describe the variable information by calling the SDK, and then synchronizes these variable information to the storage space corresponding to each flow node.

[0061] Returning to FIG. 3, in step S30, in response to an operation for acquiring the variables accessible by any flow node, the variables in the storage space corresponding to the first flow node having the first association relationship with the any flow node are acquired as the variables accessible by the any flow node, for display on the flow orchestration interface.

[0062] In some embodiments, the operation for acquiring the variables accessible by any flow node comprises: an operation of triggering the variables accessible by the any flow node to be updated; and / or an operation of triggering the variables accessible by the any flow node to be displayed on the flow orchestration interface.

[0063] For example, the operation of triggering the variables accessible by the any flow node to be updated comprises an operation of updating the variables defined on the first flow node. For example, the operation of triggering the variables accessible by the any flow node to be displayed on the flow orchestration interface comprises an operation of defining variables on the any flow node based on the variables defined on the first flow node.

[0064] In some embodiments, the first association relationship is obtained according to the flow orchestration business configuration. That is, the developer of the flow orchestration system can configure the first association relationship according to the flow orchestration business, realizing the personalized configuration of the first association relationship between multiple flow nodes, and improving the flexibility and universality of the flow orchestration business development. The universality here refers to the fact that the variable processing method provided by the disclosure can be applied to the development of flow orchestration businesses in various scenarios.

[0065] The first association relationship includes, for example, the relationship where any process node depends on the first process node. In some embodiments, the first association relationship can be a dependency relationship. For example, developers can set the rules corresponding to the dependency relationship through coding. For example, the rule corresponding to the dependency relationship can be "the node displayed in the first position in the process orchestration interface depends on the node displayed in the second position in the process orchestration interface", or it can be "when process node A points to process node B, process node B depends on process node A".

[0066] Taking a fixed-layout workflow orchestration example, a later-ordered workflow node cannot access a preceding workflow node, and variables of a child workflow node cannot be accessed by subsequent workflow nodes of its parent node. In contrast, with a free-layout workflow orchestration example, workflow node A can be connected to workflow node B via a line, allowing variables of workflow node A to be accessed by workflow node B. Dependencies can be configured based on these business requirements.

[0067] In some embodiments, obtaining variables in the storage space corresponding to a first process node that has a first association relationship with any of the process nodes includes: receiving information for accessing the storage space corresponding to the first process node, wherein the storage space corresponding to the first process node is determined according to the first association relationship; accessing the storage space corresponding to the first process node according to the information for accessing the storage space corresponding to the first process node, and obtaining variables in the storage space corresponding to the first process node.

[0068] Information used to access the storage space corresponding to the first process node includes: the identifier or access address of the storage space corresponding to the first process node. For example, the rules corresponding to the dependency relationships set by the developer through coding can be represented as a function. The input of this function is the identifier information of the storage space corresponding to any process node, and the output is the identifier information of the storage space corresponding to the first process node that any process node depends on.

[0069] In step S40, in response to the operation of updating the variable defined on any process node, the variable in the storage space corresponding to the second process node that has a second association with the first process node is updated according to the updated variable on the first process node. Multiple process nodes also include second process nodes. There can be one or more second process nodes. Taking the various steps of the variable processing method encapsulated in the SDK as an example, in the process orchestration system developed by the developer, there can be a module that receives the operation of updating the variable defined on any process node, and then this module triggers the SDK to update the variable in the storage space corresponding to the second process node that has a second association with the first process node according to the updated variable on the first process node.

[0070] In some embodiments, the second association relationship is obtained according to a process orchestration business configuration. That is, a developer of the process orchestration system can configure the second association relationship according to the process orchestration business, realizing personalized configuration of the second association relationship between multiple process nodes and improving the flexibility and universality of process orchestration business development. The universality here refers to the fact that the variable processing method provided by the present disclosure can be applied to process orchestration business development in various scenarios.

[0071] The second association relationship, for example, includes a relationship in which the second process node depends on any process node. In some embodiments, the second association relationship can be a dependency relationship or an override relationship, that is, any process node is dependent on the second process node or any process node overrides the second process node. For example, the developer can set rules corresponding to the dependency relationship or the override relationship through coding. For example, the rule corresponding to the override relationship can be "the node displayed at the second position in the process orchestration interface overrides the node displayed at the first position in the process orchestration interface", or "in the case where process node A points to process node B, process node A overrides process node B".

[0072] Taking a process orchestration business with a fixed layout as an example, a process node arranged later in the sequence cannot access a process node arranged earlier in the sequence, and a variable of a child process node cannot be accessed by a subsequent process node of a parent process node. Taking a process orchestration business with a free layout as an example, process node A can be connected to process node B through a connection line, and thus a variable of process node A can be accessed by process node B. The override relationship can be configured according to these business requirements.

[0073] In some embodiments, in the case where any process node has an override relationship with the second process node (that is, any process node overrides the second process node), the storage space corresponding to any process node also has an override relationship with the storage space corresponding to the second process node, that is, the storage space corresponding to any process node overrides the storage space corresponding to the second process node.

[0074] In some embodiments, updating the variable in the storage space corresponding to the second process node that has the second association relationship with any process node includes: receiving information for accessing the storage space corresponding to the second process node, wherein the storage space corresponding to the second process node is determined according to the second association relationship; and accessing the storage space corresponding to the second process node according to the information for accessing the storage space corresponding to the second process node, to update the variable in the storage space corresponding to the second process node. In this embodiment, the developer of the process orchestration system can directly output information for accessing the storage space through coding, so that the developer can realize personalized development and improve the flexibility of process orchestration system development.

[0075] The information for accessing the storage space corresponding to the second flow node includes an identifier or an access address of the storage space corresponding to the second flow node. For example, the rule corresponding to the dependency relationship or the coverage relationship set by the developer in a coded manner can be expressed as a function. The input of the function is the identifier information of the storage space corresponding to any flow node, and the output is the identifier information of the storage space corresponding to the second flow node covered by any flow node.

[0076] In some embodiments, the variable processing method further includes updating the variable in the storage space corresponding to the any flow node in response to an operation of updating the variable defined on the any flow node. Taking the encapsulation of each step of the variable processing method in the SDK as an example, in the process orchestration system developed by the developer, there can be a module that receives the operation of updating the variable defined on the any flow node, and then triggers the SDK to update the variable in the storage space corresponding to the any flow node.

[0077] In some embodiments, the variable processing method further includes deleting the storage space corresponding to the any flow node in response to deleting the any flow node in the plurality of flow nodes.

[0078] Taking the encapsulation of each step of the variable processing method in the SDK in the form of a pre-written code library as an example, the operation of deleting the storage space corresponding to the any flow node is expressed as a function or an interface for deleting the storage space exposed to the developer by the SDK. During the development of the process orchestration system, the developer can call the function or the interface for deleting the storage space in the variable processing method in a coded manner, so that when the process orchestrator deletes the flow node in the process orchestration interface, the process orchestration system can call the function or the interface for deleting the storage space to delete the storage space corresponding to the flow node deleted by the process orchestrator.

[0079] In some embodiments, the variable processing method further includes sending the variable accessible by the any flow node for display in the process orchestration interface. Taking the SDK as an example, there is a module in the process orchestration system developed by the developer for receiving the variable accessible by the any flow node sent by the SDK for display in the process orchestration interface.

[0080] In the above embodiments, the variables in the storage spaces corresponding to the any flow node and the second flow node having the second association relationship with the any flow node are updated in linkage, which further improves the accessibility control of the variables in the process orchestration process, thereby further reducing the development and maintenance costs of the variable subsystem in the process orchestration system.

[0081] The above is a variable processing method provided by some embodiments of the present disclosure. Next, a variable processing system device for a process orchestration procedure in some embodiments of the present disclosure will be described in conjunction with FIG. 5.
