5. SQL
SQL is the language of relational data—querying, shaping, and joining it so reports and models have the right inputs at the right time.
Why It's Important
Clean SQL means quicker reports and fewer surprises. It underpins every performant Cognos solution touching a database.
How to Improve SQL Skills
Get the basics tight: Joins, subqueries, aggregates, grouping, filtering, set operations.
Use advanced patterns: Window functions, CTEs, pivoting/unpivoting, conditional aggregation.
Read the plans: Execution plans, index usage, and statistics tell you where time is lost.
Tune with intent: Push filters down, avoid RBAR logic, reduce data movement, trim SELECT lists.
Know Cognos SQL: Understand how Cognos generates SQL from models and prompts; simplify at the model to avoid runaway queries.
Practice relentlessly: Real datasets, timed challenges, peer reviews—repetition builds intuition.
Consistency wins. Elegant SQL pays dividends across every report that touches it.

6. Data Modeling
Data modeling shapes how information is structured for reporting and analysis. In Cognos, that means building models that are accurate, fast, and aligned to the business.
Why It's Important
A sound model eliminates rework, reduces ad hoc fixes, and ensures consistent answers across teams.
How to Improve Data Modeling Skills
Start with the business: Gather grain, dimensions, measures, and usage patterns before touching tools.
Dimensional thinking: Star schemas, conformed dimensions, surrogate keys, and slowly changing dimensions—apply them well.
Data quality first: Clean, deduplicate, standardize. A pristine model cannot fix dirty inputs.
Model for performance: Pre-aggregate where sensible, partition big tables, and avoid unnecessary many-to-many traps.
Choose the right layer: Use Framework Manager for governed enterprise models; use Data Modules for agile, team-owned solutions.
Iterate: Validate with sample reports, adjust, and document assumptions and lineage.
