Once the libraries are set up, and data is entered, the job of viewing the data and making sense of it is at hand. While viewing the list of library entries, the following activities will give you the best possible look at the data and any wisdom that may be contained within it. | Once the libraries are set up, and data is entered, the job of viewing the data and making sense of it is at hand.

First, consider the tools that you define & store for later use. | |||
; Filters | |||
: First, you can restrict your investigation to a portion of the entries in the library. For example, you can filter to view orders only for a particular customer or gasoline only for your current car. Filters are defined & stored, so create those you may want to use later, during ad hoc data analysis. | : First, you can restrict your investigation to a portion of the entries in the library.

: Another tool Memento provides for data analysis is charting the data. Memento charting is very flexible, providing visual views of the data. | |||

Now we're ready for the slicing & dicing you'll do anew every time you want to look at your data. | |||

=== Putting it all together === | |||
It is not always clear how clarity and wisdom unfolds from within the data, but with artful use of these functions, one can often detect patterns in the data that would otherwise not be apparent. Use sorting carefully to enhance the effect of grouping. Grouping can often be used in place of filtering. | |||
