Design And Implementation Of The Virtual Management System Of Library

With the development of management technology of spatial information,the information management system have been transformed from 2D to 3D on spatial dimensions in many areas in the society.And with the development of the technology of GIS,3D GIS based on the technology of GIS employed in the 3D spatial system has become the future trend.The spatial management system of indoor scene based on the technology of 3D GIS is at the stage of development.It is value of to design and implement a 3D virtual management system which can be used to model automatically based on spatial data indoor in any size at any position in 3D space and can manage all the objects in space efficiently and orderly.In this paper,the indoor scene of library is taken as the research object.A management system of virtual library has been designed and implemented which can manage and automatic model based on spatial data.Firstly,combinated with the categories,the number and the spatial position of the objects in the library,a role of numbering is proposed for the management of objects in the space of library.The number generated automaticly,and updated in order.The data redundancy is reduced.The speed of retrieval of objects in the spatial is increased.Oracle Spatial technology is employed to store the spatial data.Java 3D technology is employed to display the 3D spatial data.JDBC technology is employed to connect Oracle database and Java application.The technology of analysis and processing based on the spatial data is employed in the indoor 3D management system for information.A virtual library management system is designed and implemented based on spatial data which has functions of auto modeling,management,analysis,retrieval and query.At the aspect of modeling,according to the spatial information and attribute information inputted,the model of arbitrary size is established in any position.At the aspect of management,the number of the objects in spatial generates based on the spatial data of the model.Number and model corresponded one by one.Many kinds of objects in spatial are managed efficiently and orderly.At the aspect of analysis,according to the number of click of the objects in spatial through retrieval and query,statistical analysis is executed.At the aspect of retrieval,advanced search method is employed to retrieve the objects in spatial according to the spatial information and the attributes information of the objects in spatial.The query from attribute to space is realized.At the aspect of query,through clicking the model in spatial,the spatial information and the attributes information of the objects are returned.The query from space to attribute is realized.The whole system is related with spatial information closely.
