Introducing Database-Centric Support in AUTOSAR


Publication Type:

Conference/Workshop Paper


7th IEEE International Symposium on Industrial Embedded Systems (SIES’12)


We propose to integrate a real-time database management system into the basic software of the AUTOSAR component model. This integration can be performed without violating the fundamental principles of the component-based approach of AUTOSAR. Our database-centric approach allows developers to focus on application development instead of reinventing data management techniques or develop solutions using internal data structures. We use state-of-the-art database pointer techniques to achieve predictable timing, and database proxies to maintain component encapsulation and indepen- dence of data-management strategies. The paper illustrates the feasibility of our proposal when database proxies are used to manage the data communication between components and to perform run-time monitoring on the virtual function bus. Our implementation results show that the above benefits do not come at the expense of less accurate timing predictions while only introducing a total application CPU overhead, in the order of 4%.
