Abstract

Techniques for generating software code for event processing applications are described herein. In one example, a method can include detecting, via a processor, a concept model, wherein the concept model comprises concept data related to an actor, an event, a domain, and a fact. The method can also include detecting, via the processor, a logic model comprising logic data related to event derivation and fact computation, wherein the logic model is not based on an operating environment. The method can also include creating, via the processor, a set of inferences that indicate a relationship between the concept data and the logic data. In addition, the method can include validating, via the processor, an accuracy of the logic model based on validation data, and generating, via the processor, software code based on the concept model and the logic model.

Claims

1. A method for generating software code, comprising:

detecting, via a processor, a concept model, wherein the concept model comprises concept data related to an actor, an event, a domain, and a fact;

detecting, via the processor, a logic model comprising logic data related to event derivation and fact computation, wherein the logic model is not based on an operating environment;

creating, via the processor, a set of inferences that indicate a relationship between the concept data and the logic data;

validating, via the processor, an accuracy of the logic model based on validation data; and

generating, via the processor, software code based on the concept model and the logic model.

2. The method of claim 1 comprising detecting a set of information technology elements related to the logic model.

3. The method of claim 1, wherein the fact corresponds to an attribute in a database, a data structure in a file, or an abstract data type.

4. The method of claim 1, wherein the logic data is stored in part in a computation table and an event derivation table.

5. The method of claim 4, comprising:

determining that a threshold condition in the event derivation table has been satisfied;

generating a derived event based on the satisfied threshold condition; and

storing the derived event in the event derivation table.

6. The method of claim 5, comprising:

generating a value for the fact based on the event derivation table; and

storing the value for the fact in a fact table.

7. The method of claim 1, comprising:

detecting a threshold condition to transition from one state to the next state for the event; and

storing the threshold condition in a transition table.

8. The method of claim 7, wherein the threshold condition is based on a predicate related to a mathematical operation.

9. A system comprising:

a memory device comprising processor executable instructions; and

a processor to;

detect a concept model, wherein the concept model comprises concept data related to an actor, an event, a domain, and a fact;

detect a logic model implemented with a first programming language comprising logic data related to event derivation and fact computation, wherein the logic model is not based on an operating environment of the system;

create a set of inferences that indicate a relationship between the concept data and the logic data;

validate an accuracy of the logic model based on validation data; and

generate software code in a second programming language based on the concept model and the logic model.

10. The system of claim 9, wherein the processor is to detect a set of information technology elements related to the logic model.

11. The system of claim 9, wherein the concept data is stored in part in an actor table and a fact table.

12. The system of claim 9, wherein the logic data is stored in part in a computation table and an event derivation table.

13. The system of claim 12, wherein the processor is to:

determine that a threshold condition in the event derivation table has been satisfied;

detect a threshold condition to transition from a first state to a second state for the event; and

store the threshold condition in a transition table.

16. The system of claim 15, wherein the threshold condition is based on a predicate related to a mathematical operation.

17. A computer program product for generating software code, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code executable by a processing circuit to perform a method comprising:

detecting, by the processing circuit, a concept model, wherein the concept model comprises concept data related to an actor, an event, a domain, and a fact;
