The data management system discussed in the article is specifically designed for engineering and scientific computing needs. It includes various types of data elements like numbers, vectors, and arrays, with special features for sparse and triangular arrays. The system organizes data in a hierarchical structure and allows for multiple views of the data. It also provides a way to define different structures within the data and supports different ways to manipulate the data. The system's language extensions are based on FORTRAN, a common programming language. Overall, the system aims to make managing and working with complex scientific data easier and more efficient.
