Background

In the automobile aftermarket, accessory data of mechanisms such as an accessory manufacturer, an accessory distributor and an accessory e-commerce platform generally relate to different types of accessory data such as multiple brands, multiple varieties, original factories, high imitations, packages and the like. Due to the fact that vehicle types change rapidly and intermediate links are multiple, the accessory data are miscellaneous, disordered, multiple and poor, and a unified data management standard is lacked. Further, the problems of difficult production management, difficult inventory management, blocked information, difficult after-sales service, difficult sales management and the like are caused.

FIG. 1 is a table of factory accessory inventory data in accordance with the prior art. As shown in fig. 1, existing accessory data is usually managed by using Excel or word as a carrier, and a vehicle model adapted to a product is usually filled in one cell. Fig. 2 is a conventional fitting matching table. As shown in fig. 2, the fitter typically converts the data into standard structured data through manual matching, which is labor-intensive and inefficient. The accessory dealer does not have unified standard data to do the basis when matching by oneself and marks, because to understanding deviation and the lack of data of motorcycle type data, the data accuracy after the matching is extremely low, and the later stage still need adjustment and matching many times, but only short-term use. Meanwhile, at present, an accessory manufacturer and a manufacturer do not have comprehensive and standard accessory original factory codes and functional attribute data corresponding to the vehicle type, and the limitation of self-matching data is large, which is also the main reason for leading the data to be more and more difficult to manage. Generally, manufacturers with the capability of data management need to equip a professional data product manager for each category, such as spark plugs, to perform daily data management, which is very demanding for users.
