When data is collected in one database, it is possible to use advanced analytics to gain a deep insight into how the environment has changed and what has affected the change. There are two approaches to analytics as well, one way is to analyze data as they are measured in real time, the other possibility is to use historical data from a week, month or even years ago and compare the changes. These two methods are called On-line Transaction Processing (OLTP) and On-line Analytical Processing (OLAP) .Usually large platforms also offer advanced analytics tools with great documentation, great flexibility and at a low cost.
