A system for runtime write access of data of a regulated system, comprising: a data store only write-accessible by an authorized writer; an authorized writer communicatively connected with the data store, the authorized writer being authorized to have write access to the data store, the authorized writer being configured to generate a runtime instruction communication and send the runtime instruction communication to the data store, the runtime instruction communication defining authorized data to write to the data store; and a flexible writer that is not an authorized writer and is not authorized to have write access to the data store, the flexible writer being adapted to receive a data input, the flexible writer being communicatively connected with the authorized writer and configured to: command the authorized writer to generate the runtime instruction communication and send the runtime instruction communication to the data store; intercept the runtime instruction communication sent by the authorized writer; and modify the intercepted runtime instruction communication by replacing, injecting, or updating the intercepted runtime instruction communication, during the delivery from the authorized writer to the data store, with the data input; wherein the data store is configured to execute the intercepted and modified runtime instruction communication, whereby the data input is committed to the data store. a data store only write-accessible by an authorized writer; an authorized writer communicatively connected with the data store, the authorized writer being authorized to have write access to the data store, the authorized writer being configured to generate a runtime instruction communication and send the runtime instruction communication to the data store, the runtime instruction communication defining authorized data to write to the data store; and a flexible writer that is not an authorized writer and is not authorized to have write access to the data store, the flexible writer being adapted to receive a data input, the flexible writer being communicatively connected with the authorized writer and configured to: command the authorized writer to generate the runtime instruction communication and send the runtime instruction communication to the data store; intercept the runtime instruction communication sent by the authorized writer; and modify the intercepted runtime instruction communication by replacing, injecting, or updating the intercepted runtime instruction communication, during the delivery from the authorized writer to the data store, with the data input; wherein command the authorized writer to generate the runtime instruction communication and send the runtime instruction communication to the data store; intercept the runtime instruction communication sent by the authorized writer; and modify the intercepted runtime instruction communication by replacing, injecting, or updating the intercepted runtime instruction communication, during the delivery from the authorized writer to the data store, with the data input; wherein the data store is configured to execute the intercepted and modified runtime instruction communication, whereby the data input is committed to the data store.
