Course Description

Our Microsoft SQL Server DBA and SQL Programming course (both on-prem and Azure Cloud) is designed to provide a complete learning pathway for anyone seeking to master SQL Server in today’s hybrid data landscape. Whether you are an aspiring database professional starting fresh or an experienced IT specialist looking to upgrade your skills, this course offers the knowledge and hands-on expertise you need. No prior experience is required, making it accessible to beginners, while the depth of topics ensures value for seasoned professionals.

The program begins with a solid foundation in database concepts and SQL programming using Transact-SQL (T-SQL). From there, you will gain practical knowledge in installing and configuring SQL Server, managing day-to-day database administration tasks, and implementing high availability and disaster recovery strategies to ensure business continuity. The course also emphasizes performance monitoring and tuning, equipping you with the skills to maintain stable, secure, and efficient database systems.

You will also gain hands-on experience with database migration strategies, enabling you to confidently move workloads from on-premises SQL Servers to Azure SQL while maintaining performance and data integrity.

To enhance the quality of learning, every participant receives official Microsoft courseware, including Querying Data with Transact-SQL and Administering Microsoft SQL Server Databases. These materials align with Microsoft’s certification tracks and can serve as valuable references even after the training is completed.

With over a decade of experience training thousands of students across the USA, Canada, and beyond, we are proud to offer high-quality, affordable programs in SQL Server, Azure, AWS, AI, and related technologies.

  • Trainer: Daniel

    Great mastery of the curriculum taught. Couldn't ask for more. The one thing I struggled with was the use of acronyms and abbreviations that are very strange to non IT background students. If a handout can be made with common acronyms and abbreviations in the IT field that will make the training perfect for students without an IT background. Nevertheless, f]great job Daniel. Will be referring many others to you. Many thanks.

  • Trainer: Daniel

    Daniel is excellent training provider. He has great knowledge of the Subject and on top of that he has Excellent teaching skills that thing keeps students involved in the class. He explains real time scenarios. And the class is most interactive; he answers all the questions from all the students. He is very accurate on timings throughout the classes I never seen him a minute late. He spent extra time after the class to help students. Course covered all the topics you need to know for SQL server. There are so many training houses out there; they are just interested in getting money, after getting money they really don’t have interest in providing training. It is nothing like that in Empire Data System. I strongly recommend Empire Data System if you are looking for training in SQL Server.

    I have been looking for a TSQL training for months but could not find one that fits my needs. but when i saw ad on sulekha for the Sql training and got lucky and chance to talk to the trainer, Daniel, I didnt waste any minute to register and get into the training. Thank you Daniel, keep up the good work. This is the best training I have ever got. if I missed my class he uploads us recorded video so I was able to catch up on my classes. I would recommend if anybody wants to take a SQL or database class you should take the class with him. I swear you don't go wrong and you actually learn about the SQL. he is very friendly and helpful. Daniel is very punctual and honest in his training.Thank you Daniel, keep up the good work.
