Currently, the embedded real-time database is widely applied in the embedded system and plays an important role. But on account of being mainly applied to the most important fields such as Communication, Spaceflight and Military as a key task control management, errors by it often results in irreversible fatal losses. Therefore, it is necessary to analyze the embedded real-time database key characteristics and test. This paper, by researching the characteristics, architecture and implementation technique of the embedded real-time database, analyzes its key properties including real-time transaction processing, concurrency control, recovery management, etc., and finally proposes applicable testing strategy and methods which have been proved in the actual test, being as a technique to evaluate the performance of the embedded real-time database.
