基于关系型数据库的汽车电子电路图结构化数据设计

Structural data design of automotive electronic circuit diagrams based on relational databases

根据汽车电子电路图的特点,对图元和空间结构信息进行了结构化数据表示设计。通过设计关系型数据库表和表间关系,描述了图元和空间结构信息。系统使用C++语言和SQLite数据库实现,实验表明可快速检索图元信息和连通关系。

According to the characteristics of the automotive electronic circuit diagram, we have designed structural data for graphic elements and spatial structures？ By designing relational database tables and relations between tables, we describe the information of graphic elements and spatial structures？ The system is implemented by C＋＋ language and SQLite database. Experiments show that it can retrieve graphic elements and connectivity quickly？
