Welcome to the Demo Tutorial
This demo, developed to show the capabilities of optimization techniques, is a front end to the ODBTools programs. You can introduce a new schema (either by typing a schema or by sending your own ODL schema description file), validate it and then optimize queries.Schema Validation function (under construction)
-
Type a new schema
in the ODL language
-
Validate schema coherence and minimality with respect to the
inheritance and aggregation hierarchy.
-
View the schema inheritance and aggregation hierarchy
- Alternatively, it is possible to use the Storage Company and University Database examples
Semantic Query Optimization function
-
Type a new query in the OQL language (or send it as a file) related to
the validated schema
-
Compute query optimization
-
View the query inheritance and aggregation hierarchy with respect
to the schema
- Some example queries related to the Storage Company and University Database schemas are available.
