2. Database Manipulation (I)  dbe - database editor/viewer

3. table  demo.calibration -> the calibration of the station-channel  demo.instrument -> the ancillary calibration information.  demo.lastid -> the last value used for any keys which use a counter  demo.network -> general information about seismic networks

4.  demo.schanloc -> This table maps seed chan_loc codes to a unique local channel code  demo.sensor -> The sensor table stores calibration information for specific sensor channels.  demo.site -> The site table contains station location information.  demo.sitechan -> The sitechan table contains station-channel information.

5.  demo.snetsta -> This table maps foreign seed net_sta codes to a unique local station code.  demo.stage -> Information characterizing an individual stage of the total calibration of a station-channel  demo.wfdisc -> The wfdisc table contains a waveform header file and descriptive information.

9. Database Manipulation (I)  dbcp – copy database  dbsplit - split out portions of a database  dbmerge - script to merge two databases together

10. Waveform Display (I)  dbpick – waveform review, pick arrivals, and edit a CSS relational database $ dbpick demo

11. Waveform Display (II)  trdisp - inspect waveform data and arrivals  $trdisp demo
