Every data flow that is an input to a process that updates a system data store on the data flow diagrams ( dfds ) should have at least one corresponding event in the event and enquiry catalogue 在数据流程图内每项会引致程序对系统数据储存处作出修订的数据流程,应在事件及查询目录内最少有一项对应的事件。
The design of data flow and arithmetic flow for the ict simulation system for assemblies are also discussed in detail , and the algorithm to realize the intersection of ray and phantom has been analyzed 论文详细阐述了装配体的ict计算机仿真系统的数据流程和算法流程的设计,分析了射线与样本相交的具体实现方法。
4 . a practice application for the police circs , data warehouse , olap and data mining are put forward . this application has already gained affirmation from all circs 4 、介绍了公安综合管理信息系统中的一个子系统? ?旅馆业治安管理信息系统的研制成果,设计其数据流程图、网络流程图、程序流程图以及数据结构等。
For each higher - level process each data flow connected to data stores , external entities and other processes must be carried down into lower levels . all data stores must have incoming data flows 就每个较高层次的程序,每项接连到数据储存处、外在实体及其他程序的数据流程,必须推展至较低层次的数据流程图加以详述。
This dissertation introduces the system design first , and then focuses on an analysis of several modules , and given the data structures , function interfaces , data flows and the realization processes 本文先对系统总体设计进行介绍,然后重点分析了其中几个模块,并给出了数据结构、函数接口、数据流程图等实现过程。
After analyzing the flow of system information , the direction and contents of information between each two sub - systems , and effective organization to information and interface is decided too 然后,本研究通过对系统数据流程的分析研究,确定了信息的交换方向和内容,从而确定了如何对信息有效组织和调度子系统之间的接口。
