FSDB is package of commands for manipulating flat-ASCII databases from
|
||
|
|
shell scripts. FSDB 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).
|
||
|
|
|
||
|
|
Fsdb was known as Jdb from 1991 to Oct. 2008.
|
||
|
|
|
||
|
|
Fsdb 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,
|
||
|
|
correlations, histograms)
|
||
|
|
- reformatting data for graphing programs
|
||
|
|
|
||
|
|
Rather than hand-code scripts to do each special case, FSDB provides
|
||
|
|
higher-level functions. Although it's often easy throw together a
|
||
|
|
custom script to do any single task, I believe that there are several
|
||
|
|
advantages to using this library: it is higher-level than raw perl,
|
||
|
|
control uses names intead of column numbers, it is self-documenting,
|
||
|
|
and it is very robust (error cases, careful memory handling, etc.).
