Are you looking to dive deep into the world of relational databases and unlock the power of SQL and Python? Look no further than “Teoria e Pratica dei Database Relazionali con SQL (e Python)” on Udemy. This course is a meticulously crafted blend of theory and practical application, designed to equip you with essential skills for data science, AI, web development, and beyond.
The course is thoughtfully structured into four progressive levels, guiding you from foundational concepts to advanced practical implementation.
Level one lays the groundwork by introducing the core concepts of the Relational Data Model, as defined by Edgar Codd. You’ll grasp the fundamentals of relations, attributes, data types, tuples, normalization, and keys – the theoretical bedrock of all relational databases.
Moving into the second level, the focus shifts to the logical model of data organization with the Entity-Relationship Model. This level empowers you to understand and graphically represent database logic, exploring entities, relationships, cardinality, and various relationship types (one-to-one, one-to-many, many-to-many), along with crucial elements like attribute and associative entities.
The third level plunges into the practical realm of the physical database model. Here, you’ll get hands-on experience using a real database schema. The course provides comprehensive coverage of the SQL language, breaking it down into its essential components: Data Definition Language (DDL), Data Manipulation Language (DML), Data Query Language (DQL), and Transaction Control Language (TCL). You’ll apply this knowledge to a concrete case study, solidifying your understanding through practice.
Finally, level four introduces the fascinating world of Object-Relational Mapping (ORM). This section demystifies the process of interacting with relational databases using an object-oriented approach. You’ll learn to leverage the Peewee library in Python, enabling you to build applications that interface with databases through classes, objects, methods, and properties, often without writing raw SQL.
Throughout the course, SQLite is used as the primary database management system, complemented by SQLite Studio for interactive database access. This combination provides a robust and accessible learning environment. Whether you’re a beginner or looking to solidify your database expertise, this course offers a clear, structured, and practical path to mastering relational databases with SQL and Python.
