Nowadays, more and more data are available for decisional analysis and decision-making based on different indicators. Although different decision-making technologies have been developed, we note the lack of a conceptual framework for the definition and implementation of these indicators. In this paper, we propose a first classification of these indicators. Furthermore, motivated by the need for formalism for the definition of these indicators at a conceptual level, we present the Business Intelligence Indicators (BI2) UML profile to represent indicators for OLAP, OLTP and streaming technologies. We also present their implementation in existing industrial tools. In addition, we show how these indicators can coexist in the same environment to exchange data through a chaining model and its implementation.
