ETL Concepts and Fundamentals
Introduction to ETL
  • Definition and importance of ETL in data integration
  • Role of ETL in data warehousing and business intelligence
  • ETL process flow and components (extract, transform, load)
Data Extractions
  • Source systems and data extraction methods
  • Pull-based vs. push-based data extraction
  • Techniques for extracting data from different sources (e.g., databases, flat files, APIs)
Data Transformation
  • Data cleaning and data profiling
  • Data validation and error handling
  • Transformation techniques (e.g., filtering, sorting, aggregation, join operations)
Data Quality and Governance
  • Importance of data quality in ETL processes
  • Data quality assessment and monitoring
  • Data governance principles and best practices
ETL Tools and Technologies
ETL Tools Overview
  • Introduction to popular ETL tools (e.g., Informatica, Talend, SSIS)
  • Features and capabilities of ETL tools Selection
  • criteria for choosing the right ETL tool
Data Loading
  • Types of data loading (e.g., full load, incremental load, CDC - Change Data Capture)
  • Techniques for efficient data loading (e.g., bulk loading, parallel loading) Loading data into data warehouses and data marts
ETL Best Practices and Optimization
Performance Tuning and Optimization
  • Identifying performance bottlenecks in ETL processes
  • Techniques for optimizing ETL performance (e.g., partitioning, indexing, caching)
  • Monitoring and measuring ETL performance metrics
Error Handling and Recovery
  • Strategies for handling errors in ETL workflows
  • Implementing retry mechanisms and error logging
  • Recovery procedures and rollback mechanisms
Advanced ETL Topics
Data Warehousing Concepts
  • Overview of data warehousing architecture
  • Dimensional modeling (e.g., star schema, snowflake schema)
  • ETL's role in populating and maintaining data warehouses
ETL in Big Data Environments
  • ETL challenges and considerations in big data ecosystems (e.g., Hadoop, Spark)
  • Tools and frameworks for ETL processing in big data environments
Real-time ETL and Streaming Data
  • Real-time data integration concepts
  • Implementing ETL for streaming data sources (e.g., Kafka, Apache Flink)
ETL Testing
  • Overview of ETL testing techniques (e.g., source-to-target validation, data completeness)
  • Tools and frameworks for ETL testing (e.g., QuerySurge, Informatica Data Validation Option)
Practical Applications and Case Studies
Practical ETL Projects
  • Hands-on exercises and projects to design and implement ETL workflows
  • Data integration scenarios and use cases
Case Studies and Best Practices
  • Analyzing real-world ETL implementations and success stories
  • Best practices for designing scalable and maintainable ETL processes
