To be successful and outpace the competition, you need a software development partner that excels in exactly the type of digital projects you are now faced with accelerating, and in the most cost effective and optimized way possible. Cognos provides various data solutions for different requirements of data.
Each one is meant for handling various data problems. Aggregation takes place on the fly, which degrades the performance with very large volumes of data and users.
Cube does not have any active connection to the data source, so they are said to be static. It is used for interactive analysis of operational or transactional data. It causes data latency when movement of data happens. It can be used for the analysis of a low volume of data. Dynamic Cubes are used for the analysis of large volumes of data.

They see Dynamic Cubes filling a different market need. They work by leveraging substantial in-memory data assets as well as data aggregations to achieve high performance interactive analysis and reporting over terabytes of warehouse data. In fact, most of the examples cited in this presentation focused on their role as a fast-feeder data source for reports and queries involving large amounts of data.
A key requirement is that the warehouse data needs to be structured in a star or snowflake schema in order for this to work. Scale is a key part of the conceptual understanding for the role that Dynamic Cubes are seen to play in the business analytics market.
To successfully perform high speed rendering of results from terabyte sized warehouses requires aggregation of the data. The Advisor can review a cube and recommend either in-database or in-memory aggregates which it determines will help performance. The Advisor can also review workloads of reports, packages, specific users, etc. It will also continually optimize previously created aggregates based on actual use to insure that they are tuned for fast performance.
These are not physical cubes such as Power Cubes or TM1.
