The fundamentals of management information – B
One of the most important → chart forms in our opinion. Since they fit so well in → graphical tables, bar charts have made many space-consuming, hard-to-label business charts obsolete. It is easier to compare the length of bars than the height of columns. You can use bars to display structures and columns primarily to show time series.
A rather vague term. It implies the shock of how much data there is today and the hope that you can so something worthwhile with it. We feel that → data mining has grown up. New databases that can store masses of data in memory is breathing new life into data mining, simulation, and real-time applications for financial controlling and marketing. Critics say that quantity does not automatically mean quality. That is true. (See also → data collection.) DeltaMaster treats big data in different ways. Data mining algorithms profit from the access rules quite differently. Some are ultrafast in OLAP databases while others only perform well on relational data. Some even work best with hybrid data access.
