COURSE OVERVIEW

This three-day instructor led course is about writing TSQL queries for the purpose of database reporting, analysis, and business intelligence. Specifically, this course presents TSQL within the context of data analysis in other words, making meaning from the data rather than transaction-oriented data-tier application development.

The course starts with a brief discussion of levels of measurement and quantitative research methodology, and integrates these concepts into each TSQL topic presented. The goal is to provide a consistent, direct, and purposeful learning path for RDBMS data retrieval for use in analytical tools such as SQL Server Reporting Services, PowerBI, R, and Excel.

AUDIENCE AND PREREQUISITES

This course is intended for information workers and data science professionals who seek to use database reporting and analysis tools such as Microsoft SQL Server Reporting Services, Excel, Power BI, R, SAS and other business intelligence tools, and wish to use TSQL queries to efficiently retrieve data sets from Microsoft SQL Server relational databases for use with these tools.

Before attending this course, students must have:

  • Context knowledge of data analysis and business intelligence scenarios. For example, an understanding of a work-related business intelligence project or need.
  • Basic knowledge of the Windows operating system and its core functionality, including file system navigation.
  • Basic understanding of the purpose of relational database management systems such as SQL Server.

  

*Course cost listed does not include the cost of courseware. Course is subject to minimum enrollment. If minimum is not met this class may run as a LDL / Virtual class. Please contact us @ learn@vtec.org or 207-775-0244 for additional pricing information or if you have any questions.
