Design And Implementation Of Business Object Modeling In PLM System

With the birth of enterprise information, more and more enterprises join the ranks of the information. PLM technology to companies for product development to effectively integrate the entire process, has been a growing number of medium-sized enterprises for the implementation of an enterprise information integration platform, enterprise information integration and process integration. The establishment of product information model object is the prerequisite and basis for the implementation of PLM, PLM object modeling system supports the whole building. It does this by using object-oriented means to achieve the organization and expansion of system functions, which greatly improved the system's operational flexibility and scalability. At the same time, object-oriented method to the object associated with the product all the information in a unified model of expression, form a system of consistent, global sharing of product information model.AVIDM paper in Aerospace Science and Technology launched a project context object modeling in PLM systems design and implementation. PLM system at home and abroad through research, research the current use of space within the AVIDM system problems and deficiencies, improving the design of the AVIDM underlying system structure. According to the needs of the business object model in accordance with the metadata management and external business data management were carried out design. Metadata management refers to the business of designers needs of the business in accordance with the system for business types, relationships and property design. External data management business refers to the instance of the business type or relationship management. By the way object-oriented design of the meta data services and business data base, design hierarchy between the business, business people only need to write the appropriate business code, between business objects without having to upgrade a specific life cycle management, and workflow and rights management relations. By encapsulating the object, delete, change, search and other operations to reduce the workload of business, making it focus on specific business knowledge. And, ultimately, finish the object modeling module.To verify the function of the module object modeling, object modeling, based on the design of a simple PLM system, its functions include the basic products, parts, documents and folders management. PLM system by a brief description of the design process, to demonstrate the advantages of object modeling.
