Problems solved by technology

[0005] In the current research, when information distribution software implements conditional matching and filtering, it parses the received data according to different information types, and then performs matching and filtering. Redesign and increase the analysis program of the corresponding information type, which eventually leads to the need to modify the business processing logic of the information distribution software, and affects the tight coupling between the data filtering function and the information distribution function, greatly reducing the flexibility and scalability of the software

Abstract

The invention discloses a method for applying plug-in technology to data filtering of information distribution software. The method includes the following steps: defining type identifiers of all types of information in a system, and pointing out the information type of data when an information source side sends the data and a user side subscribes for the data; defining identifiers of all types of subscription conditions in the system, and pointing out the subscription conditions in a subscription request of the user side; defining data structures of the subscription conditions; developing plug-in boards; and integrating the software and calling procedures. According to the method, the plug-in technology is adopted, reasonable plug-in interfaces and calling conventions are designed, plug-in dynamic loading and calling mechanisms are adopted, and then the condition matching and filtering functions of the information distribution software are achieved. When new information types are added into the system, a host program of the information distribution software does not need to be changed, the coupling degree between software modules can be improved beneficially, flexibility and expansibility of the information distribution software can be improved, and therefore applicability of the information distribution software can be improved.

Description

technical field [0001] The invention relates to the technical field of software system integration and function expansion, in particular to an application method based on plug-in technology in data filtering of information distribution software. Background technique [0002] Information distribution software provides network-centric system dynamic access and information distribution on demand, and is a core service in the military's shared information infrastructure. [0003] The information distribution software can filter and match all kinds of information generated in the system according to the subscription request made by the user, and finally distribute it to the user end, so as to provide users with accurate information services. According to the different attributes and fields contained in different types of information, Subscription conditions are closely related to information types. Typical subscription conditions include region, enemy and friend attributes, targe...
