Using the automation production mode of modern manufacturing industry for reference, a new industrialized PL-ISEE (product line based integrated software engineering environment) model was proposed by us in reference [8]. The middle part of the PL-ISEE architecture is data layer which is composed of the software components bus and core assets database platform to achieve the storage and managements of product line core assets data. In this paper, the architecture and its implementation mechanism of the PL-ISEE database platform is further researched. Whole platform architecture consists of core asset objects management service and assets database system. The data model and database schema as well as database views of the database platform are designed and created by using united product line concept model and data model. So, the database supporting platform’s functions and configuration also well satisfy the requirements of interfaces, tools and data integration as well as product line assembling production in the PL-ISEE. Therefore, the design and realizing ideas of the PL-ISEE database platform will be valuable to research product line engineering and methodology in future.
