In view of the characteristics of the target product, such as diverse feature data types, huge capacity, and large number of unstructured and semi-structured data, based on the domestic autonomous controllable platform, we adopt the hybrid storage architecture of massive feature data files combining relational database and Hadoop, and use relational database to store structured feature data. The Hadoop cluster is used to store semi-/ unstructured data, make up for the shortcomings of relational databases in mass data processing and storage, and achieve high concurrent access to big data of target products and scalability of heterogeneous data.

Due to the rapid information process, the amount of product characteristic data increases exponentially. In the field of product characteristic display, traditional technology can no longer meet people's needs. In this paper, a three-dimensional projection system based on stereo projection is designed to realize three-dimensional real-time projection of product characteristic data, and the three-dimensional model and product characteristics are superimposed into the holographic scene by constructing a three-dimensional model of the product. Form a display form combining static and dynamic. The representation of product characteristic data is upgraded from a simple plane form to a three-dimensional form combined with a three-dimensional model, and the relationship between product characteristics and target attitude changes is intuitively revealed, significantly improving people's understanding of product characteristic data.
