Learning outcomes
Student will be able to:
- understand the principles of relational database systems;
- analyze performance of query processing;
- optimize processed queries both by rewriting them and by creating indexes and applying other techniques;
- Explain principles of logging and recovery from failure;
- Design basic replication strategies to achieve high availability;
- Design a disk storage for the database system.
  • Introduction
  • Data storage: efficient use of secondary storage, records, blocks. Searching: index structures, sequential files, trees, hashing, multidimensional indexes.
  • Query execution: evaluation plan, algebraic laws, cost estimation, algorithms for operators, sorting and joining relations, query execution and pipelining.
  • Query optimization: contribution of indexes, referential integrity, materialized views, table partitioning, disk storage.
  • Database optimization: relational schema tuning, index optimization, database monitoring tools.
  • Transaction management: properties and their implementation, concurrency control, scheduling, data and index locking, logging and recovery from failures.
  • Database security: access rights, data security.
  • Spatial databases: indexes, operators.
  • Analytical tools.
