Abstract
A method is described for encoding and decoding stored units of data representing entity/relationship (E/R) data, function calls, and file data by including a prefix with each unit of data which includes a length code, an action code, and a unit identifier code. The data units with prefixes are organized into a data stream by using rules described in a formal grammar. The data stream will typically be transmitted to another program inside the computer or to another computer--host or PWS. When received the data stream is parsed back into data units by reversing the encoding process. After the data units are recovered the appropriate action is taken to process the units. E/R data is entered into or updated in a repository, function calls are passed on to an E/R repository function or other program along with the specified parameters for execution, and file data is stored in standard files. Generated output is captured, encoded into a data stream and transmitted back to requesting PWS which then parses the data stream to recover the output data.
