Implement a Time Dimension

• Make time-based queries simple to author by implementing a time dimension
• Resolve confusion caused by multiple relationships between a time dimension and another table

Specify Determinants

• Use determinants to specify multiple levels of granularity and prevent double-counting

Create the Presentation View

• Identify the dimensions associated with a fact table
• Identify conformed vs. non-conformed dimensions
• Create star schema groupings to provide authors with logical groupings of query subjects

Work with Different Query Subject Types

• Identify key differences and recommendations for using data source, model, and stored procedure query subjects
• Identify the effects on generated SQL when modifying query subjects, SQL settings and relationships

Set Security in Framework Manager

• Examine the IBM Cognos BI security environment
• Restrict access to packages
• Create and apply security filters
• Restrict access to objects in the model

Create Analysis Objects

• Apply dimensional information to relational Metadata to enable OLAP-style queries
• Sort members for presentation and predictability

Manage MUNs in Framework Manager

• Describe model types and data entities
• Define members and member unique names
• Identify changes that impact a MUN

Model for Drill Through in Framework Manager

• Identify conformed values between data sources
• Define a report drill through
• Define a package-based drill through
• Identify drill-through values

Advanced Generated SQL Concepts and Complex Queries

• Governors that affect SQL generation
• Stitch query SQL
• Conformed and non-conformed dimensions in generated SQL
• Multi-fact/multi-grain stitch query SQL
• Variances in Report Studio generated SQL
• Dimensionally modeled relational SQL generation
• Cross join SQL
• Various results sets for multi-fact queries

Use Advanced Parameterization Techniques in Framework Manger

• Identify session and model parameters
• Leverage session, model, and custom parameters
• Create prompt macros
• Leverage macro functions associated with security

Model Maintenance and Extensibility

• Perform basic maintenance and management on a model
• Remap metadata to another source
• Import and link a second data source
• Run scripts to automate or update a model
• View lineage
• Create a model report

Optimize and Tune Framework Manager Models

• Identify and implement techniques to optimize and tune your Framework Manager models

Work in a Multi-Modeler Environment

• Implement repository control
• Segment and link a project
• Branch a project and merge results

Manage OLAP Data Sources

• Connect to an OLAP data source (cube) in a Framework Manager project
• Publish an OLAP model
• Publish a model with multiple OLAP data sources
• Publish a model with an OLAP data source and a relational data source

Manage Framework Manager Packages

• Specify package languages and function sets
• Control model versioning
• Nest packages
