                         Abstract
    DSPACK is an object manager designed for data processing in High Energy Physics experiments. It handles C or F77 structures giving calling programs access to data through pointers, handles and names. The system implements several concepts of Object-Oriented programming - object have CLASSES and METHODS and cen respond to MESSAGES. DSPACK can be used from C, C or F77 programs and UNIX platforms. It may operate in a server/client mode - where several processes on the same machine have access to data via shared memory. All objects are defined at execution time and the persistent I/O system works in such a way that their definitions can be reconstructed in the programs which subsequently read the data. A number of classes has been written to provide interface of the system with external world (for instance HEPDB). Among the available tools there is a Motif/KUIP based DATA BROWSER DSS - it provides access to DSPACK objects from PAW and KUIP. DSPACK is used for data management in CERN experiment NA49.
