There is usually more information in a given dataset than one would expect. The Austrian Post scandal has demonstrated this impressively and gives a faint idea of what Google is capable of doing, especially given the information grows faster than linear with the amount of data.
So having more data provides you with more information, however, also quality, correlation and the links within the data itself play major roles in the information yield that can be achieved. There are many methods to extract information from data. Correlation analysis is a typical starting point that can indicate where to drill in afterwards.
Provide me with your data and I will analyse it for you. This is a job easily lost in the chores of daily business.
