Package dbshow
==============

Introduction
------------

The package provides four core functions:

1. data storage
2. data filtering
3. data sorting
4. data display

All data is saved once and then you can display these data with custom filters,
orders and styles. The package can be used, for example, to record and
display something you'd like to review, maybe the question you always answered
incorrectly or some forgettable knowledge. But obviously, the package is much
more powerful and extensible for more interesting tasks depending on the
individual.
