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 . <EOS>
