Abstract

Disclosed are various embodiments for custom result set definitions. A result set definition is obtained responsive to a request from a client. A result customization application generates and executes application program interface calls to generate response data having a fixed schema. The result customization application performs transformations on the response data to generate a result set conforming to the result set definition.

Claims

1. A non-transitory computer-readable medium embodying a program executable in a first computing device, wherein when executed, the program causes the first computing device to at least:

obtain a request from a second computing device;

in response to the request, obtain a result set definition from a data store, the result set definition defining a first schema for a custom result set to be returned in response to the request;

determine, from at least one application program interface, a plurality of application program interface calls required to obtain data reflected in the first schema for the custom result set defined by the result set definition, the plurality of application program interface calls facilitating access to data in an electronic catalog by returning on execution corresponding ones of a plurality of response sets, the plurality of response sets having at least one corresponding predefined second schema distinct from the first schema;

execute the plurality of application program interface calls to generate the plurality of response sets;

perform a transformation on the plurality of response sets based at least in part on the first schema defined by the result set definition and the request to generate the custom result set, the custom result set comprising data based at least in part on the plurality of response sets and conforming to the first schema;

communicate the custom result set to the second computing device;

wherein individual ones of the plurality of application program interface calls are associated with at least one other application program interface call of the plurality of application program interface calls in a parent-child relationship model; and

wherein the plurality of application program interface calls is determined based at least in part on the result set definition and the parent-child relationship model.

2. The non-transitory computer-readable medium of claim 1, wherein when executed, the program further causes the first computing device to at least encode for rendering a user interface facilitating a creation of the result set definition.

3. The non-transitory computer-readable medium of claim 1, wherein when executed, the program causes the first computing device to at least store the custom result set to the data store.

4. A system comprising:

a data store storing at least computer-executable instructions; and

at least one computing device comprising at least one processor and memory and in communication with the data store, the computer-executable instructions, when executed by the at least one processor, causing the at least one computing device to at least;

determine, from at least one application program interface, a plurality of application program interface calls required to obtain data reflected in a first schema for a custom result set indicated in a result set definition;

execute the plurality of application program interface calls to generate a plurality of response data sets, individual ones of the plurality of response data sets corresponding to a respective application program interface call of the plurality of application program interface calls and having a respective fixed second schema distinct from the first schema; and

perform a transformation on the plurality of response data sets based at least in part on the first schema indicated in the result set definition to generate the custom result set, the custom result set comprising data based at least in part on the plurality of response data sets and conforming to the first schema.

5. The system of claim 4, wherein the computer-executable instructions further cause the at least one computing device to at least:

obtain a request from another computing device; and

communicate the custom result set to the other computing device.

6. The system of claim 4, wherein the computer-executable instructions further cause the at least one computing device to at least obtain the result set definition from another computing device.

7. The system of claim 4, wherein the result set definition is associated with at least one related result set definition, and the plurality of application program interface calls are further determined based at least in part on the at least one related result set definition.

8. The system of claim 6, wherein the computer-executable instructions further cause the at least one computing device to at least encode for rendering a graphical user interface to facilitate creation of the result set definition by a user.

9. The system of claim 4, wherein the computer-executable instructions further cause the at least one computing device to at least store the result set definition in data storage.

10. The system of claim 4, wherein the computer-executable instructions further cause the at least one computing device to at least obtain the result set definition from data storage.

11. The system of claim 4, wherein the computer-executable instructions further cause the at least one computing device to at least restrict an amount of a plurality of transactions associated with another computing device executed in a predefined time period, wherein the plurality of transactions are generated in response to the plurality of application program interface calls.

12. The system of claim 11, wherein restricting the amount of the plurality of transactions is further based at least in part on an amount of computational resources associated with an execution of the plurality of transactions.

13. The system of claim 11, wherein restricting the amount of the plurality of transactions is further based at least in part on a size of the custom result set.

14. The system of claim 4, wherein the plurality of application program interface calls are determined based at least in part on a relationship model associating a first subset of the plurality of application program interface calls to a second subset of the plurality of application program interface calls.

15. The system of claim 14, wherein the relationship model associates the plurality of application program interface calls in a parent-child hierarchy.

16. A method comprising:

obtaining, in a first computing device, from a second computing device, a request associated with a result set definition indicating a first schema for a custom result set;

determining, in the first computing device, from at least one application program interface, a plurality of application program interface calls required to obtain data reflected in the first schema indicated in the result set definition and a relationship model associated with the plurality of application program interface calls;
