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.
