ABSTRACT:
A method, apparatus, and article of manufacture for accessing a hierarchical database. An objects framework models the database as one or more objects. An Internet-enabled generic application program accesses the database via the objects framework. The present invention introduces an Internet-enabled generic application program for accessing hierarchical databases, such as an IMS.TM. database, by modeling the database into an objects framework and then accessing the database via the objects framework using standard tools, such as the DL/I.TM. query language for the IMS.TM. database. The Internet-enabled generic application program dynamically builds a DL/I.TM. query string based on web browser inputs. The generic application program loads the objects framework to instantiate IMS.TM. objects and dynamically constructs DL/I.TM. calls to access the IMS.TM. database. The generic application program can be used in a number of different environments, such as: (1) DL/I.TM. batch processing and (2) on-line transactions including both IMS.TM. and CICS.TM. transactions. Moreover, the generic application program and objects framework can be executed in any MVS address space, including IMS.TM. and non-IMS.TM. address spaces, such as web server address spaces. With this invention, customers can continue to access their business data in IMS.TM. databases using the latest Internet technology, without relying on legacy application programs and without developing new application programs. Thus, the present invention offers improved IMS.TM. application programming productivity by supporting IMS.TM. business objects and data objects, by eliminating complicated DL/I.TM. programming, and by supporting use of object-oriented programming tools.
