With data diversification and various data visualisation methods, it is difficult to select the tool that will best meet our expectations from the wide rage of available options. The aim of this Guide is to present selected crucial issues of the Business Intelligence area, identify leading solutions related to Data Warehouses and indicate leading providers in the area of data visualisation and discovery.

The latest Gartner Business Intelligence report shows that the main objective of BI software purchasers is to exploit Big Data as far and as effectively as possible. The main obstacle companies face is not technical and visualisation capabilities of Business Intelligence tools and not data base support, but it is the fact that the majority of companies fail to accurately evaluate their business needs in this area. While technical aspects are naturally important for IT departments, business users often select tools exclusively based on the opinion from the market, and fail to consider important details. Their analysis is limited to Gartner’s quadrant for BI, with the most focus on the ease of use. They choose user-friendly tools that allow for data analysis and “submitting queries” without the involvement of the IT department. In fact, the best BI implementations come from the synergy between the IT department and the business. In this Guide, we present a selection of best practices advisable to consider when selecting the most suitable Business Intelligence solution.
