Please note that the duration and depth of each part can vary depending on the learners' needs and the desired level of proficiency. Additionally, incorporating hands-on exercises, practice queries, and real-world examples will enhance the learning experience and provide participants with practical SQL skills.

Delivery Method: This training module will be delivered in a hands-on, interactive workshop format. Participants will be provided with laptops (optional) equipped with SQL and will be guided through a series of exercises and activities to reinforce their learning. The trainer will also provide real-world examples and scenarios to demonstrate the practical applications of SQL.

Assessment: Participants will be assessed through a series of quizzes and practical exercises throughout the training to gauge their understanding and application of the concepts taught. At the end of the workshop, participants will complete a final assessment to evaluate their overall proficiency in SQL.
