Abstract

Methods and systems are presented for accessing various data values in a record stored in a data store independently from other data values in the record and without taking computationally expensive or storage-intensive procedures such as de-serializing a record based on a primary key. A data service module is provided to access each record in a data store, and generate for the records a table including a map of key-value pairs representing the data values in the records. When the data service module receives a request from an application for accessing a first data value in a first record, the data service module may retrieve a first key-value pair corresponding to the first data value in the first record without de-serializing the record. The data service module then provides a first value of the first key-value pair to the application.

First claim

What is claimed is:

1 . A data access system comprising:
a non-transitory memory; and one or more hardware processors communicatively coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to perform operations comprising:
accessing a record from a data store based on a particular primary key associated with the record, wherein the record comprises a plurality of data values associated with a user account organized according to a data structure;
generating, for the record, a table comprising a map of key-value pairs corresponding to the plurality of data values;
in response to receiving, from an application, a first request for a first data value in the record, directly accessing a first key-value pair from the table corresponding to the first data value independently from other key-value pairs in the table and without de-serializing the record based on the particular primary key; and
transmitting a first value of the first key-value pair to the application via the network as a response to the first request.

2 . The system of claim 1 , wherein the operations further comprise:
receiving, from the application, a second request for incrementing a second data value in the record; and updating the second data value by:
(i) directly accessing a second key-value pair in the table corresponding to the second data value independently from other key-value pairs in the table and without de-serializing the record based on the particular primary key; and
(ii) incrementing a second value of the second key-value pair based on the request to update the second key-value pair.

3 . The system of claim 2 , wherein the application is a first application, and wherein the operations further comprise:
receiving, from a second application, a third request for updating a third data value in the record; and updating the third data value by:
(i) directly accessing a third key-value pair in the table corresponding to the third data value; and
(ii) modifying a third value of the third key-value pair based on the request to update the third key-value pair, wherein the update to the third data value is performed in parallel to the update to the second data value.

4 . The system of claim 3 , wherein the operations further comprise:
performing a batch update process to update the record in the data storage based on the updated second key-value pair and the updated third key-value pair.

5 . The system of claim 2 , wherein the operations further comprise returning a signal indicating the second data value has been updated to the application as a response to the second request.

6 . The system of claim 2 , wherein the operations further comprise updating the record based on the updated second key-value pair.

7 . The system of claim 1 , wherein the first request comprises a first key associated with the first key-value pair.

8 . The system of claim 1 , wherein the data structure comprises a recursive data structure having a plurality of levels, and wherein the first data value is stored below a first level within the recursive data structure.

9 . The system of claim 1 , wherein the data structure is a first data structure, and wherein the operations further comprise:
constructing an object having a second data structure corresponding to the data structure of the record; inserting the first value of the first key-value pair in a first position within the second data structure of the object according to a second position of the first data value within the first data structure; and providing the object to the application.

10 . A method of accessing data, comprising:
retrieving a record from a data store based on a particular primary key associated with the record, wherein the record comprises a plurality of data values associated with a user account organized according to a data structure; accessing, for the record, a table comprising a map of key-value pairs corresponding to the plurality of data values; in response to receiving, from an application, a first request for updating a first data value in the record, directly accessing a first key-value pair from the table corresponding to the first data value independently from other key-value pairs in the table and without de-serializing the record based on the particular primary key; modifying a first value of the first key-value pair based on the first request to update the first key-value pair; and transmitting the modified first value to the application via the network as a response to the first request.

11 . The method of claim 10 , wherein modifying the first value comprises incrementing the value.

12 . The method of claim 10 , wherein modifying the first value comprises decrementing the value.

13 . The method of claim 10 , wherein the application is associated with a risk engine configured to evaluate a risk associated with a user request.

14 . The method of claim 13 , wherein the first value is used by the application to evaluate the risk associated with the user request.

15 . The method of claim 13 , wherein the user request comprises at least one of a login request for logging in to a user account, an electronic fund transfer request associated with the user account, or an on-boarding request associated with the user account.

16 . The method of claim 10 , wherein the application is a first application, the method further comprising:
receiving, from a second application, a second request for the first data value in the record; directly accessing the first key-value pair having the modified first value based on the second request; and transmitting the modified first value to the second application via the network as a response to the second request.

17 . A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause a machine to perform operations comprising:
accessing a record from a data store based on a particular primary key associated with the record, wherein the record comprises a plurality of data values associated with a user account organized according to a data structure; generating, for the record, a table comprising a map of key-value pairs corresponding to the plurality of data values; in response to receiving, from an application, a first request for a first data value in the record, directly accessing a first key-value pair from the table corresponding to the first data value independently from other key-value pairs in the table and without de-serializing the record based on the particular primary key; and transmitting a first value of the first key-value pair to the application via the network as a response to the first request.

18 . The non-transitory machine-readable medium of claim 17 , wherein the data structure is a recursive data structure comprising at least one of a list-within-a-list structure or a map-within-a-map structure.

19 . The non-transitory machine-readable medium of claim 17 , wherein the operations further comprise:
receiving, from the application, a second request for incrementing a second data value in the record; and performing an update to the second data value by:
(i) directly accessing a second key-value pair in the table corresponding to the second data value independently from other key-value pairs in the table and without de-serializing the record according to the particular primary key; and
(ii) incrementing a second value of the second key-value pair based on the request.
