【摘要】：嵌入式系统是一种独特的计算机系统，它运用先进的计算机技术，关注于具体应用，对功能性、时效性以及可靠性均有严格的约束。随着计算机科学与嵌入式技术的不断交融和渗透，嵌入式系统的相关应用不仅要求嵌入式系统能够处理大量、复杂的数据，而且要求它能有效保障其存储数据的完整性、一致性以及安全性。嵌入式数据库能借用成熟的数据库管理技术和经验，提供一套高效、可靠的方法和手段在嵌入式系统中实现对数据的检索、存储等应用。嵌入式数据库在嵌入式系统中的实现及应用，一方面，应用成熟的数据库管理技术和经验保障了应用数据的完整性、一致性和安全性，另一方面，大大降低了应用程序的复杂度，降低了数据耦合，提高了功能内聚，从而使得应用程序的可靠性和维护性得以大幅提高。本论文根据当前在国内航空电子领域的嵌入式系统中嵌入式数据库的应用需要，选择了SQLite嵌入式数据库作为研究对象，对SQLite在VxWorks嵌入式操作系统上的实现及应用进行研究，实现SQLite在VxWorks操作系统中的移植并对其进行测试验证，最后对SQLite在VxWorks操作系统中的性能进行评价。最终，本课题以结题评审的方式，验证了SQLite在VxWorks操作系统中应用的可行性，并以软件形式提交实物成果，为国内航空电子领域的嵌入式技术发展作技术储备。
[Abstract]:Embedded system is a kind of unique computer system, it uses advanced computer technology, pays attention to the concrete application, has the strict restriction to the function, the timeliness and the reliability. With the continuous integration and penetration of computer science and embedded technology, the related application of embedded system not only requires embedded system to deal with a large number of complex data, but also requires it to effectively guarantee the integrity of its storage data. Consistency and security. Embedded database can use mature database management technology and experience to provide a set of efficient and reliable methods and means to achieve data retrieval, storage and other applications in embedded systems. The implementation and application of embedded database in embedded system, on the one hand, the application of mature database management technology and experience to ensure the integrity, consistency and security of application data, on the other hand, The complexity of the application is greatly reduced, the data coupling is reduced, and the cohesion of functions is improved, thus the reliability and maintainability of the application are greatly improved. According to the application needs of embedded database in domestic avionics embedded system, this paper chooses SQLite embedded database as the research object, and studies the implementation and application of SQLite in VxWorks embedded operating system. The porting of SQLite in VxWorks operating system is realized and tested and verified. Finally, the performance of SQLite in VxWorks operating system is evaluated. Finally, the feasibility of the application of SQLite in the VxWorks operating system is verified by the way of final evaluation, and the physical results are submitted in the form of software, which makes a technical reserve for the development of embedded technology in the field of avionics in China.
