Embodiment Construction

[0064] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0065] Referring to FIG. 1 , it shows a schematic diagram of a system composed of a client terminal and a host terminal in the present invention.

[0066]The system is composed of a client 101 and an IBM host system 102, wherein the client is composed of multiple open platforms (microcomputers), and the host system is composed of a server and an IMS database system. In order to realize that the present invention extends the function of IMS access from the host to each open platform, each open platform of the client establishes a socket connection with the server through TCP / IP, and makes each open platform and the host system through TCP / IP technology Closely combined to easily realize data interaction. In order to update the seg...

Abstract

The invention provides a method for accessing an IMS database. The method is applicable to a system consisting of a client and a server, wherein the client consists of a plurality of open platforms. The method comprises the following steps that: the client receives an inputted request message; the client sends the request message to the server; the server analyzes the request message; according to the instruction analyzed by the request message, the IMS database is accessed. The prior access to the host computer is expanded to the access of common microcomputer systems, thereby bringing great convenience to the ordinary users to have the access to the data of the host computer IMS database, raising the efficiency of the access and the data processing and enlarging the user group. The invention also provides a system for realizing the access to the IMS database.

Description

technical field [0001] The invention relates to the database field, in particular to a method for accessing an IMS database and a system for realizing access to the IMS database. Background technique [0002] IBM mainframe system Z / OS is a computer system with high CPU utilization, high level of multitasking, and intensive I / O processing. It can handle different types of workloads well and provide very high reliability. Due to these advantages of the IBM mainframe system, it is widely used in business computing tasks of large and medium-sized enterprises. [0003] The IMS database system is a large-scale hierarchical database system based on the IBM mainframe system. It has a series of advantages such as large storage capacity, outstanding concurrent access performance, safety and reliability, and is widely used by many super-large enterprises all over the world. database management system. However, since IMS is a hierarchical database, it does not have the function of onl...
