Class Central Tips
This is the fourth course in the Amazon Junior Software Developer Professional Certificate. In this course on Introduction to Databases and Basic SQL Queries, you will learn essential knowledge and skills for working with relational databases and querying data using SQL (Structured Query Language). You'll start by understanding fundamental concepts like tables, rows, and columns and learn to write basic SQL queries for operations such as selecting, inserting, updating, and deleting data. You'll interact with the command line to create, populate, and query a simple database. Moving on to SQL Queries, you'll explore advanced topics, including retrieving data from multiple tables using JOINs, filtering data with WHERE clauses, and sorting/grouping data using ORDER BY and GROUP BY clauses, enabling efficient data manipulation within databases. Subsequently, you will delve into JDBC Fundamentals, gaining insights into JDBC (Java Database Connectivity), setting up JDBC drivers and connections, executing SQL queries and commands with JDBC statements, establishing database connections using DriverManager and DataSource, managing database connections effectively, and executing DDL and DML statements for database schema management and data manipulation. By the end of this course, you will be proficient in working with databases, writing SQL queries, and utilizing JDBC to interact with databases in Java applications.
After completing this course, you’ll be able to:
• Discuss different types of common database configurations.
• Manipulate datasets with Java programming tools and techniques.
• Illustrate the process of data querying and retrieval using SQL with JDBC.
