Learning track content
У цьому розділі ми навчимося фільтрувати повернені дані за допомогою оператора SELECT з використанням клаузи WHERE. Ми дізнаємося, як перевіряти на рівність, нерівність, більше та менше значущі діапазони значень, а також значення NULL.
Module 2 / Розширений Рівень SQL
У цьому розділі ви навчитеся групувати дані і працювати з ними. Для цього ми познайомимося з таким оператором, як GROUP BY. Ви також навчитеся фільтрувати згруповані дані за допомогою виразу HAVING.
Вивчіть основи мови опису даних (Data Definition Language, DDL) та мови маніпуляції даними (Data Manipulation Language, DML) в SQL, зокрема як створювати, модифікувати та видаляти об’єкти бази даних, а також як вставляти, оновлювати та видаляти дані в таблицях.
Module 3 / Реляційні Бази Даних та Нормалізація
У цьому розділі ви познайомитеся з реляційними та нереляційними базами даних і навчитеся створювати діаграми для представлення структур баз даних.
Цей розділ заглиблюється в тему реляційних баз даних і надає вичерпний огляд ключових теоретичних концепцій. Розглядаються такі теми, як зовнішні ключі, різні опції ON DELETE та різні типи звʼязків.
Настав час навчитися створювати бази даних, зосередившись на забезпеченні добре структурованої бази даних для оптимальної функціональності. У цьому розділі ви ознайомитеся з ключовими принципами побудови зручної у використанні бази даних.
Module 4 / Advanced Techniques in SQL
Now we explore the basic principles of ACID (Atomicity, Consistency, Isolation, Durability) in database management. Learn how these principles ensure reliable transactions by guaranteeing complete operations, keeping data consistent, isolating concurrent transactions, and ensuring permanent data storage.
Explore how to enhance the efficiency of your SQL queries through index optimization. Delve into the significance of indexes in database performance, learning how to design, implement, and utilize them effectively. Discover strategies for choosing the appropriate indexes, understanding their impact on query execution plans, and optimizing query performance through index selection and utilization.
This section explores pivotal topics such as Triggers, Window Functions, and DCL (Data Control Language), offering comprehensive insights into their implementation and optimization strategies. Furthermore, it navigates the landscape of NoSQL DBMS, providing a thorough understanding of its architecture, advantages, and practical applications.
Requirements
  1. A computer with a browser - all browsers are supported.
  2. Your enthusiasm to enhance your tech skills.
  3. Everything else needed to start learning and practicing is already included in this course.
