Cheat Sheet
- Understanding ETL Workflow and Session Fundamentals -
Mastering workflows and sessions is critical for organizing and executing ETL tasks in Informatica PowerCenter. According to Informatica's official documentation, a workflow groups Control and Session tasks to define execution sequences, while Session properties control mapping execution details like source and target connections. A quick mnemonic - "Workflow Controls, Session Executes" - can help you remember these roles during your Informatica exam prep.
- Key Transformations: Expression, Lookup, Joiner, and Aggregator -
The Expression transformation lets you perform row-wise calculations using built-in functions, while Lookup and Joiner enable data enrichment by fetching related records from reference tables. Aggregator supports summary operations like SUM and AVG, which are essential for BI reporting as noted in industry journals like TDWI publications. Use the acronym "ELJA" (Expression, Lookup, Joiner, Aggregator) to recall core transformations when tackling Informatica certification sample questions.
- Optimizing Performance with Caching and Partitioning -
Performance tuning in Informatica often involves optimizing cache settings for Lookup and Aggregator transformations and implementing partitioning to parallelize data flows, as recommended in the Informatica PowerCenter Performance Tuning Guide, which is crucial during an Informatica Certification Practice Test. For instance, increasing the Lookup cache size can reduce database hits, speeding up ETL jobs in high-volume BI scenarios. A handy formula - "Cache Size = (Source Row Count × Row Size) + 1MB" - can help set initial cache parameters.
- Data Warehousing Concepts: Star Schema and Slowly Changing Dimensions -
Understanding star and snowflake schemas is vital for designing BI solutions; fact tables connect to dimension tables in a star schema, simplifying queries as per TDWI best practices. Slowly Changing Dimensions (SCD) types 1, 2, and 3 manage attribute history - SCD2, for example, uses surrogate keys to track row versioning. A mnemonic like "Keep, Track, Overwrite" can help differentiate SCD types on your Informatica data warehousing quiz.
- Managing Repositories and Version Control -
Efficient repository management ensures organized metadata and secure version control across development, test, and production environments, as outlined in the Informatica PowerCenter Administration Guide. Utilize object version labels and folders to track changes and support team collaboration for your Informatica BI practice exam prep scenarios. For a quick tip, adopt the "Folder-Label-Comment" routine when checking in objects to maintain clear audit trails.
