Design And Implementation Of Activities Information Dissemination System Based On Map And Search

With the strengthening of the professional communication,different kinds of academic lectures are growing at an unprecedented speed.Due to academic activities are hard to avoid a large number of foreign teachets and even non-native persons to participate in,so a special system which collect academic lectures information is important for the persons who are going to participate in.At present there is no this kind of system for academic activities holding information in the domestic,the only some information releaseing system can't display the activity address in the map and search the academic activities and lectures by latitude and longitude.Nowadays,modern maps and GIS technology provide basic technical support for LBS.In this context,this paper proposes a design solution special for releaseing academic activities holding imformation which is full use of modern map technology and search engine technology,and according to this designed solution to implement a information releaseing system,and this system allows users to releaseing academic activities holding imformation and mark on the map easily.Participants can according to the keywords or the coordinates from the map to search the nearby related information.According to the above analysis of the problems existing in the academic activities holding information and the designed solution,the main work of this paper includes the following parts:(1)combin the study of activity information releaseing system existing problems,analyse the current activity releaseing information systems' problems including lacking of geographic information and then put forword a full-text retrieval and geographic search based activity information releaseing system;(2)Do demand analysis for this releaseing system based on geographic location,use case diagrams are given the corresponding functional description,points out two core of the system requirements,release and seach,and searching including keywords seaching and geographical seaching;(3)According to the front requirement analysis,from the Angle of software engineering,come out the design and implementation of the system,mainly including the relational database tables,the object of the system model,database cluster.On this basis to the design and module partition of the system.After the division,give the design and implementation of the module,finally using map technology and search engine technology to develop an activity information releaseing system based on geographic location;(4)After the system unit test,I also did the black box tests in addition to the performance tests,proved that the system satisfy the needs and solve the problems of the academic activities releaseing and the system has certain stability and practicability.
