1. What are the contributions in this paper?
Rather than viewing programming as an art and the programmer as the perpetual artist, structured programming provides a more.. With these in mlnd the authors propose a `` structured '' Data Structure facility, which they call a Data Structure Description and Manipulation Language ( DSDML ) to maintain a similar terminology to other groups ( see CODASYL Report ~ ] ).. The DSDML provides data structure definitions in addition to the data definitions available in the host language ( e. g. PL/1 or COBOL ).. The main advantages of such a facility can be summarized as follows: ( i ) It provides ( some ) control mechanism over the behavior of data structures.. The permlsslble operations in the DSDML are more restricted than those in the CODASYL Report, but allow the creation of a wide variety of commonly used structures.. This follows from the fact that the DSDML allows for definitions of multilevel data structures, in which the nodes of a given level structure serve as headers for the structures at the next level.
