Writing Analytical Queries for Business Intelligence Training Course (55232-A)

Course 55232-A: Writing Analytical Queries for Business Intelligence Certification Training Course Overview

This course is about writing TSQL queries which is 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 will be starting with a brief discussion of levels of measurement and quantitative research methodology, and integrates these concepts into each TSQL topic presented. The goal of this course is to provide participants 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

  • Information Workers and Data Science professionals who prefers to use database reporting and analysis tools like Microsoft SQL Server Reporting Services, Excel, Power BI, R, SAS and other business intelligence tools, and is willing to use TSQL queries to efficiently retrieve data sets from Microsoft SQL Server relational databases for use with these tools.
