Product data management is actually a very complex task, and product information can be effectively shared through product data management in product design. Based on the analysis of the concept and development of product data management, this paper briefly introduces the application of product data management in enterprises.

Product data management is a technology that specializes in the management of product-related information and design process, which has a very broad use value, and a wide range of applications, including machinery, industry, automotive, aerospace, education and other industries. At present, data management technology has been widely used in Europe and the United States and other developed countries, and in other developing countries is also in the trend of prairie fire. In China, product data management technology has been put into use in a considerable number of enterprises.

1 the concept of product data management

Product data management (PDM) is a new data management technology with the continuous development of information technology. It monitors the formation of product data scientifically by using solidified module structure, and manages the data information or documents that need to be processed in data formation.

After systematic analysis of product data management technology, we can clearly know its basic principle, that is, effectively combine scattered CAX information, break the situation of isolated information island, use Internet technology to control the development process of product information, and finally present product information description, product design information description and product data description and management by building a virtual product model.

Continue to promote the effective combination of information technology system and management information system, so as to provide a technical basis for the formation of the whole product. At the same time, strengthen the construction of the computer integrated manufacturing system, through the virtual product model, the product data management system makes full use of its effective, scientific and complete advantages to manage the data of the whole life cycle from product planning to product depreciation.

Product data management takes the product as the core medium and manages all the data related to the product in the enterprise design and production process through the Internet technology and database platform to ensure the accuracy and authenticity of the product data information in the whole process. Provide a collaborative office environment for enterprise technicians, adopt concurrent engineering, shorten the time from product development to market, reduce production and design costs, improve product quality, so as to enhance the core competitiveness of enterprises, let enterprises occupy a place in the market competition, and lay a solid foundation for enterprises to realize information management.

2 the development process of product data management

Product data management is the overall management technical framework of engineering data management, document management, product information management, technical data management, technical information management, image management and other product information management. At present, product data management is widely used in the United States and other developed countries, and has achieved remarkable results, which has a strong practical significance and research value.

2.1 initial Product data Management products

In the early 1980s, the first generation of product data management technology was born. At that time, CAD technology was very mature and has been widely used in various fields. Enterprise engineers have to waste more energy and time on the information resources needed by product design while experiencing the convenience and advanced nature brought by CAD technology.

In order to improve and make up for the deficiency of CAD technology, the major software developers have launched the first generation of product data management products on the basis of CAD technology software. the main function is to solve the problem of management and storage of large-scale electronic data, and has the function of "electronic drawing platform". The development of the primary product data management products alleviates the bad situation of the isolated island of product information to a certain extent, but due to the limited factors such as development capability and technology, there are still many problems in the primary product data management products. it is mainly reflected in the weak system function, lack of integration ability and so on.

2.2 second-generation product data management products

On the basis of the improvement and optimization of the primary product information data products, software developers have launched the second generation product data management products, which are more powerful than the original products. At the same time, the second generation product data management products determine the important position of product data management technology in enterprise information system. In the process of enterprise application, CAD, CAPP and other technologies are integrated through the product data management system to establish the core management position of product data management in enterprise design and product production data.

Product data management technology is mainly used in enterprise engineering design departments to provide enterprises with real information of all kinds of product data. the development of second-generation product data management products makes the concept of product data management deeply rooted in the hearts of the people. it has aroused numerous repercussions in the information software industry. The product function of the second generation product data management has been recognized by various industries. at the same time, as a second generation product data management product, compared with the original generation, it is more advanced in technology.

2.3 Product data Management Standardization stage

With the continuous improvement of scientific and technological means, product data management is also constantly improving and developing. with the different definitions of product data management by developers, product data management technology is also full of tricks, but they all have one thing in common, that is, the development is more perfect, and the content of science and technology is getting higher and higher. At the same time, the logical model of product data management and the operation of system functions are standardized.

3 Analysis of the current situation of product data management

The birth of product data management has a great impact on the information integration of product development, the management level of product development technology, as well as the efficiency of product development, and injects strong vitality to the enterprise. At present, the technology has achieved good results at home and abroad, and its use in developed countries has been very perfect and mature.

According to the investigation and analysis of product data management by American CIM company, this technology is widely used in manufacturing industry, and has become a hot technology in this industry. In the United States, more than 50% of enterprises are using product data management technology. What is more exaggerated is that this kind of data management technology is used by foreign aerospace, automobile, manufacturing and other enterprises. It has become one of the important technical means for enterprises to maintain strong competitiveness.

In Japan, General Motors, Ford Motor Company, OMRON and other companies are also using product data management technology to achieve inter-time, cross-space distributed product collaborative development model. Based on the statistics of a large number of references, it is found that the application of PDM technology can shorten the product development cycle by about 25%, in which the modification of engineering design can reduce the modification rate by 14%. To speed up the process of putting products into the market by about 70%, and reduce product development costs by 25%.

In recent years, with the continuous promotion of enterprise information construction in our country, product data management technology has been paid attention to by enterprises and become an important part of enterprise information construction. However, compared with the developed countries in Europe and the United States, there is still a certain gap in the understanding and application of product data management in Chinese enterprises. although many enterprises have purchased product data management software, the utilization rate is not high. It has become a kind of decoration. Even if some enterprises are using software technology, they do not have an in-depth understanding of product development management and the reform of R & D mode. it is only superficial to use the document data management function of product data management software in the process of product development. There is a small proportion of people who can really use all aspects of PDM system in the field of complex product development.

Compared with foreign product data management technology, although the product data management products independently developed in China have reached the standards of the second generation product data management products in developed countries in terms of performance, function and stability, however, there is still a big gap compared with the third generation product data management products. However, domestic self-developed product data management software is more in line with the development needs of Chinese enterprises than foreign products.

4 the application of product data management method in enterprises

4.1 effectively solve the security management of enterprise data and documents through product data management technology

In the process of enterprise production and operation, document information and electronic data in folder management not only have the risk of information leakage, but also face the security hidden danger of data loss. the method of product data management can solve this problem very well, make full use of the information backup function of the database, combined with the security management function of the software itself, strengthen the security of document and data information. So as to ensure that all employees in the enterprise can safely use and obtain the required data information within the scope of their authority, but do not worry about the leakage and loss of the data. And the data information obtained through the product data management software is true and reliable, which can reduce the complicated process of data information verification.

4.2 build a perfect R & D system through product data management technology

At present, the R & D system of Chinese enterprises is not perfect, which limits the scientific research and development of enterprises, and the method of product data management can use information technology to help enterprises build a standardized, reasonable and perfect R & D system. In this system, enterprises can plan the product development cycle reasonably and allocate human resources scientifically. And protect the product quality in the process of product development. At the same time, the data of each stage of product development can be managed at any time, so as to understand the progress of product development and make appropriate work adjustments according to the progress. And can supervise the work of the employees through the product data management software, which lays the foundation for the objective evaluation of the employees.

4.3 Review and endorsement of product design data through product data management technology

Product data design must go through the work from the beginning of drawing to the final examination and approval before it can formally become the release of data information. in this process, it contains two key points of work. the first is how to ensure the security of design data in and out of the process, and the second is to strengthen the supervision of product development cycle in the process of checking and signing design data.

In order to ensure the accuracy, authenticity and consistency of the pick-up and check-out work, two different types of spatial structures need to be created, namely, the workspace and the shared area. The main purpose of the workspace is to provide a transition bridge for the local design data, that is, to extract the local design data from the workspace to the shared area, and to review and sign the design data in the shared area.

At the same time, if the design work changes, it is convenient to extract information directly from the shared area to the work area, lock and save the shared area storage data automatically after extraction, and automatically unlock the shared area data by re-checking in the working area after modification. And retain both the original version and the changed version.

4.4 improve the accuracy of enterprise design through product data management technology

The application of product data management system can fully ensure the latest acquisition and use of project data by enterprise personnel, so as to avoid the repetition rate in product design and ensure the consistency of product design. The application of product data management technology in enterprises can improve the accuracy of product design and accelerate the pace of product listing.

4.5 help enterprises establish standardized operation flow through product data management technology

The R & D and design of enterprise products is a very complex and difficult process. At present, although Chinese enterprises have achieved certain results in the accumulation of product development experience, the ability of product innovation needs to be improved. Coupled with the lack of advanced and perfect management level, it is the focus of the current work for enterprises to introduce a model that can help them establish a standardized operation process, and the emergence of product data management technology. It happens to solve this kind of dilemma faced by enterprises. So as to guide enterprises to move towards a standardized management system.

Through the establishment and use of standardized operation process, all departments of the enterprise can obtain complete and accurate data and information, shorten the product development cycle, accelerate the speed of product listing, and constantly improve the work efficiency of the enterprise. Based on the premise of standardization process, the product data management system can promote the interaction and exchange of personnel among various departments of the enterprise, and provide more effective and reasonable suggestions for product development. In order to achieve the purpose of optimizing the allocation of resources and improving the workflow.

5 conclusion
