When to use in-memory
In-memory analysis is a specific data warehousing solution that should be used only in appropriate use cases. It will not solve all of your data storage and reporting needs. However, used effectively it add significant benefit to BI projects.
The figure below illustrates that as data complexity and volumes grow the appropriate solution for handling them will change.
Where in-memory analysis excels is:
1. Departmental BI projects – few data sources, low level of data transformations.
2. Rapid Integration for ISV’s – the ability to quickly integrate reporting on top of an OLTP application.
3. Short term BI analysis – through away analytical projects that need rapid access to data in an agile manner.
4. Data Source is slow – when the data source being accessed is slow due to the complexity of the schema being reported against.
