| Abstract: | Subsequent with the development of embedded database system, improvements in data query are urgently required. Based on the embedded database system have designed, the SQL complier is successfully implemented using tools of Lex arid Yace. Furthermore, preliminary optimization researches have been proposed on the generated syntax analysis tree. The result indicates that the compiler remarkably reinforces the SQL query capacities. |
