این دوره برای مدیران و توسعه دهندگان پایگاه داده و هوش کسب و کار حرفه ای در نظر گرفته شده است. البته به احتمال بسیار زیاد این دوره مورد توجه کسانی که الزاما وظیفه آنها در پایگاه داده متمرکز نشده و یا طرح و برنامه ای برای شرکت در آزمون  ۴۶۱-۷۰ ندارند یعنی، ایجاد کنندگان گزارش، تحلیلگران کسب و کار و توسعه دهندگان نرم افزار نیز، مفید خواهد بود.

طراحان پایگاه داده، توسعه دهندگان و مدیران پایگاه داده SQL Server در سازمان ها و نهادهای دولتی و غیردولتی نیز از مخاطبان این دوره خواهند بود.

شرکت کنندگان در این دوره، پس از پایان دوره قادر خواهند بود تا:

• کوئریهای مختلفی را ایجاد کنند.
• تغییرات در کوئری ها داشته باشند
• با پایگاه داده SQL Server به راحتی کار کنند.
