Abstract: A method to send instructions to distributed Data Bases has a stage where directives are formatted in a document respecting an appropriate formalism, a stage in which the document is sent, one in which the document is interpreted and translated into basic instructions and, finally, one stage where those instructions are executed under the supervision of a Supervisor, so that the Data Producer does not remain bound to supervise the results of basic transactions. Moreover, an example of formalism to be used to format the document containing the directives is also described.
