The Design And Realization Of Base Data Manage System Using Joint C3 Information Exchage Data Model

For data and information management,many large systems are now facing similar problems,the data requirements of different operational applications are distinct,the difference between the systems led to the exchange of data in different systems becomes difficult.Meanwhile,the real-time data requirements of the system in combat space are relatively high,led to diversified data,the data processing becomes complicated.The data management system manages all the data needed in combat space,combat applications.As the data management system to manage the data is diverse,and the demand for storage and processing of complex data types,relational database has been unable to meet the demand.JC3IEDM,Joint Command,Control and Consultation Information Exchange Data Model.It is an intermediate standard for the information exchange of the combat command and control system.It is the most basic specification of the common interface of battlefield information exchange.This system establishes the database of the combat data management system which adopts the JC3IEDM data model as the standard,stores and processes all kinds of data in the combat space.First,the background of the system,the development of data management at home and abroad and key technologies of JC3IEDM data model and object relational database used in system development were introduced.Secondly,based on the defined standards and criteria of the JC3IEDM data model and the requirements of the system,a more detailed classification criterion is defined,and the JC3IEDM data model is better used.Then,we use the object relational database to define the complex object and object relational model,and use object-relational model and relational model to combine the object-oriented idea and relational database,and get the object relation of each module of the system.Finally,the design and implementation of the data management system are described.The design and implementation of the module is described in detail.The pattern mapping rules are defined.The model mapping rules are used to implement the instance storage and query.The data management system and the data management system are implemented.Other combat systems use XML to interact with each other.The system operation and test results shows that the system is stable and easy to operate.The system uses a relational database to implement when using an object relational database.Through the operation and test results of the two,this paper illustrates the use of object relational database and JC3IEDM The necessity of the data model shows that the system can meet the requirements of additional systems and achieve the expected goals.
