Information Sources

This section describes the basic concept for Information Sources in IFS Applications.

IFS Information Sources provide a business oriented view of information available in IFS Applications, used for information output. The information Sources hides the underlying, often complex, data structures and offers an interface optimized for reporting and analysis. There is a wide range of Information Sources available in different product areas.

Using IFS Information Sources makes information access much easier compared to connecting directly to IFS Applications database. Users do not need to understand the technical data structures to build reports, Lobby elements or to connect from other BI tools. The information is organized in a logical, business oriented way with relevant measures and information attributes that can be directly used.

Most Information Sources have two access modes – Online or Data Mart. In Online mode Information Sources are directly connected to IFS Applications production data, offering full up-to-date reporting and analysis capabilities. Using Online access is in many cases not optimal for performance. In these cases, Data Mart mode can be used. Data Mart mode means that information is stored in a separate Data Mart, updated on a regular basis according to configuration

The overview represents a Star Schema model, refer to Figure 2. The model consists of  a main transaction entity called Fact and associated basic data entities, so called Dimensions.

In IFS Business Reporting & Analysis the entity Information Source means a Fact and one or more associated dimensions plus associated metadata.

Entity Name Description
XlrFact Information about available Information Sources
XlrFactItem Information about fact items, i.e. Information Source details
XlrDimension Information about available dimensions (basic data)
XlrDimensionItem Information about dimension items, i.e. basic data details
XlrSourceNavigator Describes the structure of the so called BR Client Navigator where each leaf node represents a link to a fact (Information Source).
Through the BR Client Navigator the end-user gets access to data sources in the IFS Business Reporter client.
