The Neo4j company has updated its free online training course, "Introduction to Neo4j," to provide a more comprehensive and hands-on introduction to graph databases and the Neo4j graph database platform. The new 8-hour course is designed for beginner students and includes 16 hands-on exercises that can be completed in either Neo4j Desktop or a Neo4j Sandbox. To complete the course, students need to install Neo4j Desktop on their machine or create a Neo4j Sandbox, and they will receive a certificate of completion if they pass all quizzes correctly. The updated course is essential for becoming a Neo4j Certified Developer and covers topics such as Cypher queries, CRUD operations, constraints, indexes, and importing CSV data into Neo4j.
