JDB is a package of commands for manipulating flat-ASCII databases
from shell scripts. JDB is useful to process medium amounts of data
(with very little data you'd do it by hand, with megabytes you might
want a real database). JDB is very good at doing things like:
* extracting measurements from experimental output
* re-examining data to address different hypotheses
* joining data from different experiments
* eliminating/detecting outliers
* computing statistics on data (mean, confidence intervals,
histograms, correlations)
* reformatting data for graphing programs
Rather than hand-code scripts to do each special case, JDB provides
higher-level functions.
JDB is built on flat-ASCII databases. By storing data in simple text
files and processing it with pipelines it is easy to experiment (in
the shell) and look at the output.
