Automatic Grading System on SQL Programming
Dalian（2009）
摘要
Structured Query Language is an important teaching content of computer science, due to its strong practicability. However, there is no such practical SQL-based paperless examination system, because of the difficulty lies in the proper and effective mark of the SQL programming question. This paper provides a series of set operation algorithms as an effective solution of the questions above. By the transformation of the DML statement, so that the correctness of DML statement with no return set can also be verified, which make the verification of SQL programming questions a reality.
