A computer-aided design and production management of distributed information processing strategies
That the same application to edit the object. Since the object is embedded, so the source document will not be affected. Link the object to be ~ dealing with a reference from the source document sent to the target document; in other words, the target text block contains only a link to the source document, containing the links to modify a target document, it will open the Create the linked object that application, which allows you to modify the source document,[link widoczny dla zalogowanych], use the link object, sharing information must be updated at any time. Clearly, there is the difference between information spaces: the linked object is stored in source documentation; the embedded object is stored in the target word document. If you want to share information between multiple applications, and that each application has access to current information, consider using the object linking technology. Obviously, the link technology much faster than the embedded technology. Processing shown in Figure 2. In the client-server system using embedded graphics and data link technology to modify the remote, you can consider some of the server need to modify the graphical data to the local copy, then use the object embedding and linking techniques to modify and update the file server the corresponding graphical data, and other customers at this time there is no access to the graphics file permissions. For inquiries, you do not need to consider updating the graphics data problem. 3. Dynamic Data Exchange Dynamic Data Exchange {DDEJ the basic principles are based client application (hereinafter referred to as the client side) and server applications (hereinafter referred to as the service side) in the form of pairs to achieve the exchange of information, that client-side applications and services through to start entering into data exchange session client side j then sends the data to the service can request to send data and commands, the service to complete the appropriate treatment, and the results sent back to cut the Client; when the client side data and services no longer needed , the customer application for suspension of the session in order to free up system resources 4 J Liu Fei Gong Gong Qu Arrow: A computer-aided design and production management of distributed information processing strategies 53 cAD graphic files embedded technology embedded link technology and links loop 2 technology in a distributed computer-aided design contrast ring and production management systems. . This would greatly reduce the volume of documentation and the library occupied hard disk capacity can be linked graphic files on the server to the client, DDE to allow content. Selection, simply select the layer that need, and pass into the dynamic data required to promise not to intervene. There are 3 types of DDE links, that is cold,[link widoczny dla zalogowanych], mild hot links. Link much like the cold snapshot. Transmit data only once, and then it will not transfer; temperature link is similar to the clipboard transfer, data transfer only when the client requests; on the hot link, if the client-side data changes, it will re-send. When the user needs to process graphics files, you can consider the file on a file server with the client to establish the link temperature, no other user has updated request,[link widoczny dla zalogowanych], send a request to send data. 3.3 circle circle-based database established in the engineering design, elevation and more, if the shape of each elevation were treated, the need to establish a large number of graphical database, the workload and disk capacity are not allowed. According AlI | IocAD can establish the fact that many layers can be divided into several parts of the elevation. Also under the layer of transparency, can freeze and other characteristics, in building a database different entities will be painted in different layers, so that each record in a relational database corresponding to each level of graphics, library structure shown in Figure 3. Layer file name database record ID 3 ring ring ring bank structure characteristics, the system will accordingly modify the standard library of graphics files, need to get the graphics. In the client / $ t Works control system, SQL Server is stored in the gallery above, graphics files stored on a file server. When a customer needs to modify the graphical information, the library section of the record can be locked until the modification is completed. 4 Conclusion The management of computer-aided design and computer aided integration issue is a new topic, from concepts, theories, techniques and methods need to vigorously conduct research, explore and achieve. Especially in the C / S system, graphical information and data to achieve information sharing is a difficult problem to solve, we propose a way of thinking, to a certain extent, solve the graphic file sharing. To achieve higher portability share,[link widoczny dla zalogowanych], needs further discussion and study. References 1 Ma Ri-jie.
