Main concepts

5. / Template
4
Template is the standard layout
of document.
For each analytical document the
template versioning is enabled.

6. / Dataset
5
Each document is associated to
one or more datasets.
The dataset provides actual data
that will be represented according
to the defined template.

7. / Datasource
6
In order to retrieve data via the
dataset, a source of information
must be defined.
The data source may be
associated to the document
either directly or implicitly
(through dataset).

8. / Generation
7
These elements are then
combined inside each document
engine, in order to produce
different analytical documents.

20. / KPI / Measure
19
To create a measure:
▪ Define the calculation rule through a SQL query
▪ Indicate the metadata of the rule, namely identify
• MEASURES
• ATTRIBUTES

21. 20
/ KPI / Creation
Define a calculation rule based on measures
Define the KPI cardinality, namely the aggregation of the
KPI under measures attributes
Define thresholds
Define targets

22. Define the cardinality level of KPI under measures attributes
Define a higher aggregation level than the basic measures one

Thresholds management allows to reuse the same thresholds in different KPIs

24. It is possible to define KPIs targets, namely the optimum of each KPI
