چکیده

Dimensions and tolerances are critical engineering design information for defining shape requirements of manufactured parts. As technologies for new design analysis and manufacturing planning are being developed, they must be seamlessly integrated into a computer aided product development environment. A data model is an effective technique to define the shareable semantics that are essential to the success of data communication in an integrated environment. This paper introduces a data model for dimensions and tolerances. The model is a component of an overall product data model. The dimension and tolerance data model has three major components: dimension schema, tolerance schema, and datum and shape aspect schema. These schemas specify data resources and structure for describing dimension and tolerance characteristics of products. Based on this model, descriptions of dimensions and tolerances of products can be communicated between tolerance-related software application systems.

Critical Success Factors for Data Virtualization: A Literature Review

Data Virtualization (DV) has become an important method to store and handle data cost-efficiently. However, it is unclear what kind of data and when data should be virtualized or not. We applied a design science approach in the first stage to get a state of the art of DV regarding data integration and to present a concept matrix. We extend the knowledge base with a systematic literature review ...
