Method, apparatus, and computer readable medium for generating an audit trail of an electronic data record

An apparatus for generating an audit trail of an electronic data record, the apparatus comprising:

• one or more processors;
• and
• one or more memories operatively coupled to at least one of the one or more processors and having instructions stored thereon that, when executed by at least one of the one or more processors, cause at least one of the one or more processors to:
• receive a request to generate an audit trail of the electronic data record, the request comprising a record identifier of the electronic data record and a date value;
• identify a plurality of commit data structures corresponding to the electronic data record based at least in part on the record identifier, each commit data structure corresponding to a set of changes previously applied to one or more fields of the electronic data record and comprising a timestamp value, a list of one or more changes made to one or more fields of the electronic data record, and a prior commit pointer pointing to a prior commit data structure corresponding to a previous set of changes applied to one or more fields of the electronic data record;
• identify one or more commit data structures in the plurality of commit data structures that are pertinent to the request based at least in part on the timestamp value of at least one commit data structure and the date value;
• and
• generate the audit trail of the electronic data record based at least in part on the list of one or more changes in each commit data structure in the identified one or more commit data structures.

At least one non-transitory computer-readable medium storing computer-readable instructions that, when executed by one or more computing devices, cause at least one of the one or more computing devices to:

• receive a request to generate an audit trail of the electronic data record, the request comprising a record identifier of the electronic data record and a date value;
• identify a plurality of commit data structures corresponding to the electronic data record based at least in part on the record identifier, each commit data structure corresponding to a set of changes previously applied to one or more fields of the electronic data record and comprising a timestamp value, a list of one or more changes made to one or more fields of the electronic data record, and a prior commit pointer pointing to a prior commit data structure corresponding to a previous set of changes applied to one or more fields of the electronic data record;
• identify one or more commit data structures in the plurality of commit data structures that are pertinent to the request based at least in part on the timestamp value of at least one commit data structure and the date value;
• and
• generate the audit trail of the electronic data record based at least in part on the list of one or more changes in each commit data structure in the identified one or more commit data structures.
