1. A method for database query formulation and access comprising the steps of:

  • reading identification data from an identification tag that uniquely identifies the identification tag;

    querying a computer database to determine whether the identification data is stored in the database;

    electronically storing classification data in a data memory that identifies an item associated with the identification tag with the identification data if the identification data is not stored in the database;

    receiving a state identifier indicating a state of the item associated with the identification tag if the identification data is stored in the database;

    determining whether a state of the state identifier is an allowed state based on whether the item has been checked out to a predetermined individual prior to the use of the authenticated item by the predetermined individual in a public performance, wherein the use of the item by the predetermined individual in the public performance transforms the item into a unique authenticated item;

    modifying the state of the state identifier if the state of the state identifier is not an allowed state; and

    storing the state of the state identifier with the identification data if the state of the state identifier is the allowed state.
