Course description

The course aims to develop the essential skills to optimize a relational Database and to give an overview of the main alternative technologies for data persitence related to the big data phenomenon, so to promote the informed choice of the most suitable system for each use case.
Most of the course is on physical Database optimization, and at the end the main related skills will be to read an execution plan and to decide when ad how indexing, multidimensional clustering, range partitioning or materialized views should be recommended in relation systems.
Concerning non relational systems, the student will be able to decide autonomously which data solution is the most adequate given the nature of the data and the requirements to be fulfilled.
Advanced features of PL/SQL will be presented, together with rudiment of NoSQL technology.
A project that adds advanced functionalities and the capability to store and manage non relational data through polyglot system is required to be developed and discussed.
Knowledge and understanding:
A good autonomy in managing and optimizing a relational DBMS, reading an execution plan and mastering PL/SQL is required.
Knowledge of fundamentals of NOSQL models (key values, document store, graph based, columnar) is required, so to be able to decide which technology
should be preferred and under which circumstances.
Ability to apply knowledge and understanding:
the ability to add non trivial functionalities and multiple solutions to an existing Database is expected.
Communication skills:
the project must be rigidly documented with a precise language and UML diagrams.

Prerequisites

Fundamental relational Database theory and practice acquired through the first Database course during the bachelor degree is necessary, while it is recommended familiarity with Algorithms and Data Structures.

Syllabus

Physical Design: Data Structures, indexing, execution plans; concurrency control; reliability; Active Databases; DDBMS and NoSQL; Big Data; Data Warehouses; Database Mining; Advanced features of PL/SQL.

The course will treat in depth the physical design of relational DBMS, so to give to the students the ability to properly tune in terms of performance a relational database; furthermore it will give a broad overview of the most recent alternatives to relational systems explaining the proper use cases for each of them.

Teaching Methods

Taught classes with blackboard and chalk and practical exercises. There are no slides and active participation of students is encouraged.

Learning assessment

The final verification is organized in two steps: the project and the oral discussion. For a given Database, the project consists in discussing the execution plan of some queries and in adding functionalities for unstructured data chosen in the NoSQL world.
