• Fundamental operational concepts: session management, spool usage, and locking mechanisms
• System connectivity protocols via Teradata Studio, BTEQ, or SQL Assistant

Module 2: SQL Querying Fundamentals in Teradata

• Core syntax: SELECT, WHERE, and ORDER BY clauses
• Data type definitions and conversion casting
• Application of mathematical and date-time functions
• Implementation of aliases and CASE logic expressions
• Proprietary Teradata operators: TOP, QUALIFY, and SAMPLE
• Practical application: Executing queries against active data tables

Module 3: Advanced Query Structures: Joins, Subqueries, and Set Operations

• Join methodologies: INNER, LEFT, RIGHT, and FULL OUTER associations
• Managing cross-joins and Cartesian products without explicit ON conditions
• Scalar and correlated subquery construction
• Set operations: UNION, INTERSECT, and EXCEPT (MINUS)
• Applied exercises in data integration and consolidation

Module 4: Analytic Functions and Online Analytical Processing (OLAP)

• Ranking functions: RANK(), ROW_NUMBER(), and DENSE_RANK()
• Grouping data via PARTITION BY syntax
• Defining analytic windows using OVER() and ORDER BY
• Offset and value retrieval functions: LAG(), LEAD(), and FIRST_VALUE()
