OVERVIEW

The course provides basic skills on the design of information systems and on the conceptual, logical and physical structure of relational databases

AIMS AND CONTENT

LEARNING OUTCOMES

Introduction to Relational Databases and their life cycle, design tools, languages ​​for the creation-querying, manipulation of centralized databases.

AIMS AND LEARNING OUTCOMES

Entity/Relationship Model - the expected results are the ability to generate an Entity/relationship model starting from a verbal description of a management information system

Classic DB models in particular the relational model the expected results are the ability to translate an E/R diagram into a relational schema

Algebraic foundations of the relational model - the expected results are the ability to manipulate relational algebraic expressions and the knowledge of the characteristic algebraic operators

the SQL language the expected results are the ability to learn the language instructions to write queries in SQL and to translate algebraic expressions into SQL queries

Normalization theory up to 4NF. - the expected results are the ability to learn the theoretical foundations of the relational model, the concepts of functional dependence and the theory of normalization up to 4NF

The OODB and ORDB object models. the expected results are the ability to understand the differences between classic and object oriented models and the ability to convert a relational schema into an object-oriented one

linear index structures the expected results are the ability to understand the concept of index and taxonomies, insert, delete and search operations in linear indexes

Tree indexes B+ the expected results are the ability to understand the concept of searching through tree structures the properties of tree indexes, particularly B+ and the operations of inserting, deleting and searching tree indexes B+

Hash Indexes The expected results are the ability to understand the concept of Hash function and its application to information search the properties of static and dynamic Hash indexes and operations of insert, delete and search in Hash indexes

PREREQUISITES

Knowledge of the fundamentals of programming and notions of mathematical analysis

TEACHING METHODS

Frontal lessons in the classroom with aids

SYLLABUS/CONTENT

The course will focus on fundamental aspects of transactional systems, on specific programming languages, on information integrity theories. In the first part, database design issues will be addressed both from a conceptual and logical point of view, the Entity/Relationship models will be presented, as well as the classic DB models, in particular the relational model. In the second part, the algebraic foundations of the relational model, the SQL language and the theory of normalization up to 4NF will be presented. In the third part we will analyze the embedded languages ​​for DB access, ODBC, JDBC, the object models OODB and ORDB. In the last part, the issues relating to physical data storage, linear index structures, B+ tree and Hash will be explored

EXAMS

EXAM DESCRIPTION

Written test consisting of a conceptual design of a database using an entity relationship diagram and the writing of some queries in relational algebra and sql language and oral test in which the theoretical and practical aspects of the program will be analyzed in detail through questions. The written tests are scheduled, the oral tests are agreed with the teacher and can only be carried out after the written test has been completed.

 

ASSESSMENT METHODS

Acquire familiarity with the basic issues related to transactional systems with particular reference to conceptual modeling, E/R diagrams; to traditional logical models particularly relational; to the SQL language also embedded in procedural languages; to the normalization process up to 4NF; to index structures.
