Dynamic query sequences for retrieval of negotiable instrument image

A computer-implemented method for processing a request for an image of a negotiable instrument that was utilized in a completed transaction, the method comprising:

• receiving a request for the image of the negotiable instrument utilized in the completed transaction from a first computer through a first network at a second, intermediate computer, the second, intermediate computer hosting an on-line banking program and being in communication with a third computer of a financial institution through a second network;
• and
• determining, with a sequence program associated with the on-line banking program, a dynamically modifiable sequence of queries comprising respective query configurations available to attempt to retrieve the image from a data store including a plurality of images of respective negotiable instruments that were utilized in respective completed transactions, the sequence being determined by the sequence program based at least in part upon first historical data of whether respective query configurations were used in the past to retrieve respective requested images from the data store;
• submitting a query of the determined sequence from the second, intermediate computer to the data store;
• receiving a result generated by executing the query of the determined sequence;
• submitting at least one additional query to the data store according to the determined sequence;
• and
• receiving at least one additional respective result generated by executing the at least one additional query of the determined sequence, the sequence program executing to dynamically modify the historical data and the determined sequence based at least in part upon the at least one additional respective result.

A system for determining a sequence of queries for retrieving an image of a negotiable instrument in response to a request received from a first computer at a second, intermediate computer, the second, intermediate computer hosting an on-line banking program and being in communication with a third computer of a financial institution through a second network and with a data store comprising negotiable instrument images, the second, intermediate computer being configured to receive the request while the first computer is utilized to access the second, intermediate computer during an on-line banking session to view transaction history within an account hosted by the financial institution, the system comprising:

• a database comprising historical data of whether respective query configurations were successfully used in the past to retrieve respective requested images of respective negotiable instruments that were utilized in respective completed transactions from the data store;
• and
• a sequence program associated with the on-line banking program and the database, the sequence program being configured to receive a first request for a first image of a first negotiable instrument utilized in a first completed transaction from the first computer through a first network at the second, intermediate computer, determine a first sequence of queries comprising respective query configurations available to attempt to retrieve the first image from the data store, the first sequence being determined based at least in part upon first historical data of whether respective query configurations were successfully used in the past to retrieve respective requested images from the data store, submit a first query of the first sequence from the second, intermediate computer to the data store, receive a first result generated by executing the first query of the first sequence, generate second historical data by updating the first historical data with the first result, and determine a second sequence of queries comprising respective query configurations based at least in part upon the second historical data.

A computer program product comprising a non-transitory computer readable storage medium embodying one or more instructions executable by a computer to perform a process for determining a sequence of queries for retrieving an image of a negotiable instrument that was utilized in a completed transaction in response to a request received from a first computer at a second, intermediate computer, the second, intermediate computer hosting an on-line banking program and being in communication with a third computer of a financial institution through a second network and with a data store comprising images of respective negotiable instruments utilized in respective completed transactions, the second, intermediate computer being configured to receive the request while the first computer is utilized to access the second, intermediate computer during an on-line banking session to view an account hosted by the financial institution, the process comprising:

• receiving a first request for a first image of a first negotiable instrument from a first computer through a first network at a second, intermediate computer that hosts an on-line banking program and is in communication with a third computer of a financial institution through a second network, determining, with a sequence program associated with the on-line banking program, a first sequence of queries comprising respective query configurations available to attempt to retrieve the first image from a data store comprising a plurality of negotiable instrument images, the first sequence being determined based at least in part upon first historical data of whether respective query configurations were successfully used in the past to retrieve respective requested images from the data store, submitting a first query of the first sequence from the second, intermediate computer to the data store, receiving a first result generated by executing the first query of the first sequence, generating, with the sequence program, second historical data by updating the first historical data with the first result, and determining, with the sequence program, a second sequence of queries comprising respective query configurations based at least in part upon the second historical data.
