摘要:
A method, apparatus, and article of manufacture for accessing a hierarchical database using an object-oriented programming model. The database is modeled into an objects framework, wherein the objects framework corresponds to application views, data structures, and data defined and stored in the database. The database is then accessed through the objects framework. A class definition tool generates class definitions for objects that encapsulate or wrapper the data retrieved from the database.
摘要:
A method, apparatus, and article of manufacture for accessing a hierarchical database. The database is modeled into an objects framework, wherein the objects framework corresponds to application views, data structures, and data defined and stored in the database, as well as message queues. Data is retrieved from the objects framework in response to a query request received from an application program, wherein the query request conforms to a syntax that supports one or more data types used by the database system.
摘要:
A method, apparatus, and article of manufacture for accessing a hierarchical database. The database is modeled into an objects framework, wherein the objects framework corresponds to one or more application views, database definitions, and data defined and stored in the database system, one or more message queues for communicating with the database system, and one or more system services of the database system Transactions from an application program are processed through the objects framework using the message queue objects. System services provided by the database system are invoked from an application program through the objects framework using the system services objects.
摘要:
A method, apparatus, and article of manufacture for accessing a hierarchical database. The hierarchical structure of a database is modeled into an objects framework, wherein the objects framework is comprised of one or more objects that correspond to application views, database definitions, and data defined and stored in the database, and the objects are organized into a tree structure to represent the hierarchical structure of the database. An Internet-enabled application accesses the hierarchical structure of the database through the objects framework using at least one multi-frame output form, wherein the multi-frame output form displays data from a plurality of the objects.
摘要:
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.
