Data Analysis & OLAP
Query and Analysis tools let users quickly find answers to the business-related questions with ad-hoc analysis software interfaces. End users don't need to know much about data sources or technical data structures and they're able to build queries, format reports and perform basic analysis operations on their own.
OLAP is a technology that enables the business a free selectable, quick, easy to use and interactive access to relevant information - which is arranged in a multidimensional model.
This can be realized by such tools as OLAP Analysis software, ad-hoc query and reporting tools, in-memory OLAP solutions and other.
