Topic: Transmission of tasks between processes
There are some processes which perform any operation. They thus fulfill it sequentially, i.e. one process fulfilled - transfers any to another, but that can be now occupied or is not launched absolutely not. In this connection it would be desirable to organize somehow queue, but a simple file a-lja xml does not approach, since it is required:
a) the Synchronous access: while one process writes there the job of the second to this moment can try to delete the existing;
Since records will be often deleted, it is required that the file size did not increase because of "garbage".
Any DB arises, of course, but for the sake of basis on 3-4 labels with pair tens records to lift the DB server not especially it would be desirable. Here on mind comes any FB Embedded but how at it with business point are?
And generally, it can be solved somehow more gracefully, I am simple not in course?.
