Distinguish between Cognos Dynamic cube and Transformer/TM1 cube and PowerPlay cube?

Cognos Dynamic Cube, Transformer/TM1 Cube, and PowerPlay Cube are three different types of cubes used in IBM Cognos Business Intelligence software. Here are the key differences between these cubes:

• Cognos Dynamic Cube: Cognos Dynamic Cube is a type of cube in Cognos BI that allows users to create and explore multi-dimensional data models in real time. It provides fast, interactive analysis of large and complex data sets. The dynamic cube uses in-memory technology to enable high-speed querying and analysis. It also allows users to build their own calculations and metrics.
• Transformer/TM1 Cube: Transformer/TM1 Cube is a type of cube in Cognos BI that is built using Transformer, which is a data modeling tool. It uses a relational database as its data source and creates a multi-dimensional cube that can be used for reporting and analysis. Transformer/TM1 cubes are typically used for planning, budgeting, and forecasting applications.
• PowerPlay Cube: PowerPlay Cube is a type of cube in Cognos BI that is built using PowerPlay Transformer, which is a data modeling tool. It uses a dimensional database as its data source and creates a multi-dimensional cube that can be used for reporting and analysis. PowerPlay cubes are typically used for analysis of historical data.

In summary, Cognos Dynamic Cube is a real-time cube that uses in-memory technology, Transformer/TM1 Cube is a cube built using Transformer for planning and forecasting, and PowerPlay Cube is a cube built using PowerPlay Transformer for historical data analysis.
