Semantic Layer - Contexts and Universes

This section provides information about contexts.

IT Business Analytics includes out-of-the-box Context (universes) that correspond to specific aspects of the business.The entities in these Contexts are IT Data Model-compliant. For details about IT Data Model, see IT Data Model.

ClosedTo access:

In IT Business Analytics, click Admin > Semantic Layer > Semantic Layer. In the Context Management page, click Launch Context Designer. In the Context Designer page, click  Open an existing context, and select the Context.

ClosedContexts Created using SAP BusinessObjects Enterprise

A Context (universe) represents a business universe.

A Context is a set of entities. Each entity is a set of fields. Each field can be a dimension, measure, or fact. It can be measured.

A formula calculates, for a specified time period, using the values of specific entities, a value that represents a specific aspect of the business. The value is given to a Key Performance Indicator (KPI). The KPI represents the specific aspect of the business.

Each universe includes some KPIs. The KPIs are the building blocks of the Studio and the KPI engine.

The universe entity relationship diagrams (ERDs) are logical views of the universe data models. The ERDs are interactive and contain details about the tables and classes used in the universe.

ClosedSemantic Layer - Contexts and Universes

ITBA semantic layer includes Contexts and universes.

The Context Designer feature enables you to create and manage Contexts (universes). The Contexts can be based on your target schema tables or on Excel (or .CSV) files that can be uploaded to the target schema using the Data Loader.

Context Designer can be used to upload data and create contexts based on the data, when you want to work with the IT Business Analytics application without using Data Warehouse and SAP BusinessObjects Enterprise. It is a direct way to upload data into the IT Business Analytics Studio using files without performing integrations to external sources or to other HP products. It can be used, to integrate third party data, testing, or for Proof of Concept (POC) sessions. It can also be used as a component of IT Business Analytics to integrate third party data.

Context Designer provides KPI results based on your real data.

ClosedPlan the integration of the relevant data sources and the activation of the corresponding Content Packs

  1. Learn about KPIs and Metrics (Activate Scorecards, Perspectives, Objectives, Metrics, or KPIs Using Templates.)
  2. Consult the list of KPIs and Metrics for each data source in the Content Reference Guide(or in the KPI Library in Excel format - you can sort the list according to the business context).

    This document is accessible from the Help Center page in the online Help Center (documentation library), or from the HPE Software Product Manual Site (https://softwaresupport.hpe.com/group/softwaresupport/search-result?doctype=manuals?keyword=).

  3. Understand the structure of the Contexts and about the KPIs or Metrics and their relation to Contexts. For details, see Semantic Layer - Context Designer See also, SAP BusinessObjects Enterprise Contexts (Universes)
