LEARN-SQL is a system conforming to the IMS QTI specification that allows on-line learning and assessment of students on SQL and other database skills in an automatic, interactive, informative, scalable and extensible manner. This tool facilitates the definition of virtual laboratories or remote questionaries that are used by students of subjects to learn design and use of relational databases in the UPC.

5. Subjects and Assessment
Test Cases (TC);
Students
TC Weights;
Solution
TC Results for a teacher
correct solution.
Subjects:
• SQL queries
• SQL insertions, updates and
deletes
Scorer:
• SQL creation of tables
• Execution of the students solution for • Relational databases design from
each TC. UML conceptual models
• Comparison of the results with the • Normalization
• Stored procedures
ones of the teacher solution. • Triggers
• Return the TC that failed the • Views definition
comparison. • Assertion simulations by means of
views definition
• JDBC applications
• Database optimization
• Algebra
• Query cost estimation
Failed TC • Multidimensional operations

6. System architecture
• Authoring Tool: Client
Java program that allows
exercises management
(items)
• Scorer: Web Service with
an specific module for
each subject exercises
evaluated
• Remote Test Module:
Moodle 1.9 extension
(teams definition,
LearnSQL quizzes, peer-
review evaluation)
• Scalability: As many scorers as necessary can be added in order to offer a good response time to a
certain number of students using concurrently the system. These scorers can be deployed in
different servers in order to offer parallel assessment
• Extensibility: New modules can be added to the scorer in order to assess new subjects, or scorer
implementation can be changed in order to offer assessment of other type of exercises
