Disruption index for tracking database records

A method of processing tickets in the event of an involuntary ticket exchange, the method comprising:

• receiving a query identifying a reissue ticket stored in a ticket database, wherein the reissue ticket is associated with a previous exchange of a parent ticket;
• retrieving, from a transitional database, a transitional record indexed to the reissue ticket, the transitional record containing a disruption index that includes at least one array which defines a set of linked coupon elements, wherein each linked coupon element is associated with a status and at least one of the linked coupon elements corresponds to a coupon from the parent ticket;
• determining, in response to a disruption, the coupon from the parent ticket has not been exchanged based on the status associated with the at least one of the linked coupon elements corresponding to the coupon from the parent ticket;
• identifying, based on determining the coupon from the parent ticket has not been exchanged, a set of tickets in the ticket database that include at least one of the linked coupon elements, the set of tickets including the parent ticket, the reissue ticket, and a replacement ticket;
• generating a disruption history from the set of tickets, including:
• initializing a first array with coupon elements from the parent ticket and the reissue ticket,
• adding at least one coupon element from the replacement ticket to the first array,
• selecting a latest previously unselected coupon element from the replacement ticket,
• determining a status of the selected coupon element,
• in response to the status indicating the selected coupon element was exchanged, setting an exchange flag and discarding the selected coupon element,
• in response to the status indicating the selected coupon element was not exchanged, adding the selected coupon element to one of a second array or a third array,
• in response to the selected coupon element being the earliest coupon element of the replacement ticket, update the disruption history by:
• appending the second array to the first array before the earliest coupon element of the first array, and
• appending the third array to the first array after the latest coupon element of the first array;
• and
• generating a hybrid ticket from the disruption history, including:
• determining a first value for the hybrid ticket using a pricing engine,
• assigning the first value to the reissue ticket,
• determining a second value for the replacement ticket using the pricing engine,
• determining a third value equal to a difference between the second value and the first value, and
• assigning the third value to the replacement ticket.

A computer program product for processing tickets in the event of an involuntary ticket exchange, the computer program product comprising:

• a non-transitory computer-readable storage medium;
• and
• program code stored on the storage medium that, when executed by one or more processors, causes the one or more processors to:
• receive a query identifying a reissue ticket stored in a ticket database, wherein the reissue ticket is associated with a previous exchange of a parent ticket;
• retrieve, from a transitional database, a transitional record indexed to the reissue ticket, the transitional record containing a disruption index that includes at least one array which defines a set of linked coupon elements, wherein each linked coupon element is associated with a status and at least one of the linked coupon elements corresponds to a coupon from the parent ticket;
• in response to a disruption, determine the coupon from the parent ticket has not been exchanged based on the status associated with the at least one of the linked coupon elements corresponding to the coupon from the parent ticket;
• identify, based on determining the coupon from the parent ticket has not been exchanged, a set of tickets in the ticket database that include at least one of the linked coupon elements, the set of tickets including the parent ticket, the reissue ticket, and a replacement ticket;
• generate a disruption history from the set of tickets, including:
• initializing a first array with coupon elements from the parent ticket and the reissue ticket,
• adding at least one coupon element from the replacement ticket to the first array,
• selecting a latest previously unselected coupon element from the replacement ticket,
• determining a status of the selected coupon element,
• in response to the status indicating the selected coupon element was exchanged, setting an exchange flag and discarding the selected coupon element,
• in response to the status indicating the selected coupon element was not exchanged, adding the selected coupon element to one of a second array or a third array,
• in response to the selected coupon element being the earliest coupon element of the replacement ticket, update the disruption history by:
• appending the second array to the first array before the earliest coupon element of the first array, and
• appending the third array to the first array after the latest coupon element of the first array;
• and
• generate a hybrid ticket from the disruption history, including:
• determining a first value for the hybrid ticket using a pricing engine,
• assigning the first value to the reissue ticket,
• determining a second value for the replacement ticket using the pricing engine,
• determining a third value equal to a difference between the second value and the first value, and
• assigning the third value to the replacement ticket.
