Brief introduction

Learn how to design and create the semantic BI layer that will enable self-service data analysis and ensure consistency of delivered information across your organisation 

Description

Regardless of the information governance model in place, information professionals responsible for the design, build, deployment and maintenance of corporate data analysis capability are feeling the pressure to deliver more information assets in the shortest period of time possible.

The advanced semantic layer structure provides a single version of facts for all system users and applications and provides transparent views of corporate information to all stakeholders and participants in the analytical processes. A Common Information Model provides authorised users with consistency of semantics across various business units, subject areas, analyses and reports. It allows the implementation of a common organisation-wide business and technical language, which is essential for the effective discovery, access, use and sharing of information.

This course will enable BI administrators and specialists to deliver information models that allow the query process to become a natural process by enabling analysts to structure queries in the same intuitive fashion as they would ask business questions.  It will teach participants to define complex business measures in calculations, expressed in business terms and deliver a consistent dashboard view for the relevant KPIs, enabling flexible and fast data exploration and discovery and supporting rapid visual analysis in a consistent manner and in accordance to establish information governance practice.
