Course Description

  
This three-day instructor led Microsoft SQL Server 2016 Training Course is about writing TSQL queries for the purpose of database reporting, analysis, and business intelligence. Specifically, this Microsoft SQL Server 2016 Training 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 Microsoft SQL Server 2016 Training 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.
Course Length: 3 Days
Course Tuition: $1290 (US)

Prerequisites
Audience: This Microsoft SQL Server 2016 Training 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.

Course Outline

  
Module 1: Introduction to TSQL for Business Intelligence
 
This module discusses writing analytical queries vs. transactional DML queries, and describes the typical architecture of a business intelligence environment. It discusses the role of SELECT queries in retrieving data for analysis from relational databases. It introduces the sample database to be used in the Microsoft SQL Server 2016 Training Course, and begins a presentation of the SELECT query.
 
Lessons
 
Two Approaches to SQL Programming
TSQL Data Retrieval in an Analytics Environment
The Database Engine
SQL Server Management Studio and the CarDeal Sample Database
Identifying Variables in Tables
SQL is a Declarative Language
Introduction to the SELECT Query

Create and execute basic SELECT queries
After completing this module, students will be able to:
 
Describe the purpose of analytical queries
Describe the function of TSQL data retrieval in an analytics / business intelligence environment
Describe the primary functions of the database engine
Discuss TSQL as a declarative language
Identify variables of interest in database tables
Write basic SELECT queries
 
Module 2: Turning Table Columns into Variables for Analysis: SELECT List Expressions, WHERE, and ORDER BY
 
This module covers the identification of and relationship between levels of measurement and column data types. It continues a discussion of the SELECT query and adds the WHERE and ORDER BY clauses.
 
Lessons
 
Turning Columns into Variables for Analysis
Column Expressions, Data Types, and Built-in Functions
Column aliases
Data type conversions
Built-in Scalar Functions
Table Aliases
The WHERE clause
ORDER BY
Lab : Lab 2- Write queries using:
 
Column and table aliases
DISTINCT
WHERE
ORDER BY
Built-in functions
Explicit and implicit data type conversion
After completing this module, students will be able to:
 
Implement column expressions in SELECT queries
Implement column and table aliases
Describe data types and Implement data type conversions
Implement built-in functions
Use WHERE and ORDER BY clauses in SELECT queries
 
Module 3: Combining Columns from Multiple Tables into a Single Dataset: The JOIN Operators
 
Module 3 discusses creating single datasets for analysis by combining results from multiple database tables using JOIN.
 
Lessons
 
Primary Keys, Foreign Keys, and Joins
Understanding Joins, Part 1: CROSS JOIN and the Full Cartesian Product
Understanding Joins, Part 2: The INNER JOIN
Understanding Joins, Part 3: The OUTER JOINS
Understanding Joins, Part 4: Joining more than two tables
Understanding Joins, Part 5: Combining INNER and OUTER JOINs
Combining JOIN Operations with WHERE and ORDER BY
Lab : Lab 3- Write SELECT queries using:
 
Inner join
Left, right, and full join
Joins of more than two tables
Join operators, in addition to WHERE and ORDER BY
After completing this module, students will be able to:
 
Discuss and describe the conceptual flow of JOIN operations
Implement INNER and OUTER JOIN operations on two or more tables
Describe the order of operations of SELECT clauses
Combine JOIN operations with WHERE and ORDER BY
 
Module 4: Creating an Appropriate Aggregation Level Using GROUP BY
 
This module covers the aggregation of quantitative column values across grouping factors for the purpose of group-wise comparisons and/or changing the granularity of a dataset.
 
Lessons
 
Identifying required aggregation level and granularity
Aggregate Functions
GROUP BY
HAVING
Order of operations in SELECT queries
Lab : Lab 4- Write queries using:
 
Aggregate functions

After completing this module, students will be able to:
 
Describe row granularity of result sets
Discuss and implement aggregate functions to achieve required row granularity
Use GROUP BY to calculate aggregate values for groups
Use HAVING to filter records in the result set by aggregate value
Combine GROUP BY and HAVING with WHERE and ORDER BY
 
Module 5: Subqueries, Derived Tables and Common Table Expressions
 
This module covers the use of subqueries, derived tables, and common table expressions in SELECT queries as techniques for creating intermediate result sets.
 
Lessons

Module 6: Encapsulating Data Retrieval Logic
 
This module discusses the encapsulation of data retrieval logic in views, table-valued functions, and stored procedures. It also describes scenarios in which these techniques are useful for producing datasets for analysis. Finally, it describes the database security issues involved, and techniques for creating and using these database objects while maintaining current permission sets on source data.
 
Lessons
 
Views
Table-valued functions
Stored procedures

Module 7: Getting Your Dataset to the Client
 
This module covers common techniques for making datasets produced by SELECT queries available to analytical client tools such as SQL Server Reporting Services, PowerBI, Excel, and R. It discusses running queries directly from the client tool, in addition to exporting datasets to text files which can then be accessed by the client tool.
