On this page I will publish slides, exercises and other material for the course.

  1. Databases and Queries  (Slides)

  2. Relational Algebra  (Slides)

  3. First-order Query Languages  (Slides)

  4. Conjunctive Queries  (Slides)

  5. Datalog  (Slides)

  6. Incomplete Databases  (Slides)

    Sudeepa Roy has summarized Chapter 19 of Foundations of Databases on slides for her course Understanding Data.

  7. SPARQL 

    Slides on syntax and semantics of SPARQL are on the pages of the course Semantic Technologies, which I taught in 2014/15.



These are exercises that we have discussed in the lab sessions.
  1. Queries in Calculus, Algebra, and SQL

    To run the SQL queries you wrote, download this main memory dbms, which already contains data for the movie database.

    To check your solutions, you may want to compare them with these sample solutions.

  2. Satisfiability of Comparisons

  3. Execution Plans in PostgreSQL

    We created a company db and a graph db, and checked execution plans for company queries and graph queries.



Here are the questions for the coursework:
  1. Satisfiability, Safety, and Containment (Assignment, Sample Solutions)

  2. Positive and Conjunctive Queries (Assignment, Sample Solutions)

  3. Evaluation and Containment of Conjunctive Queries (Assignment, Sample Solutions)

  4. Containment and Minimization of Conjunctive Queries and Their Unions (Assignment, Sample Solutions)

  5. Incomplete Databases and Tables (Assignment)
