CrNiCKL (pronounced "chronicle") is a database for time series written in Java running on top of SQL and NoSQL systems. This package provides a few demos.
Version 2.0.0 tracks changes in the Time2 Library t2 2.0.0
The distribution consists of three archives
crnickl-demo-x.y.z.jar crnickl-demo-x.y.z-javadoc.jar crnickl-demo-x.y.z-sources.jar
with compiled classes, HTML documentation, and sources. The version number
x.y.z follows the maven convention. The distribution also includes .asc
files with detached cryptographic signatures.
Building the software
$ git clone https://github.com/jpvetterli/crnickl-demo.git $ cd crnickl-demo $ mvn install
This builds and installs the distribution JARs in your local maven
repository. They can also be found in the
When building the software by other means, the following dependencies must be addressed:
x.y.z with the actual version numbers which can be found in the
POM file included in the binary JAR:
Running the demos
The following command executes the
$ mvn -q exec:exec Database : sa@jdbc:hsqldb:mem:demodb Value types (with base type) : +-- Currency (Currency) | +-- | +-- CNY - Yuan renminbi [... lots of output removed ...]
(Everything after the first line is the output of the command.) The same can be done with:
$ mvn -q -Ddemo.mainClass=ch.agent.crnickl.demo.stox.StocksAndForexDemo \ -Ddemo.args="file=stox-text.parm,file=jdbc.parm" exec:exec [... output removed ...]
Note: this was executed in a Unix shell, which supports line continuation with a backslash. In case your shell or command window does not do this, write the command as one long line.
Another demo produces some graphics:
$ mvn -q -Ddemo.mainClass=ch.agent.crnickl.demo.stox.StocksAndForexDemo \ -Ddemo.args="file=stox-graphic.parm,file=jdbc.parm" exec:exec [... most output removed ...] /tmp/FBI_KGB_raw.svg /tmp/FBI_KGB_in_USD.svg /tmp/FBI_KGB_in_USD_adj.svg
A third demo deals with time series of geo locations:
$ mvn -q -Ddemo.mainClass=ch.agent.crnickl.demo.geocoord.GeoCoordDemo \ -Ddemo.args="file=geo.parm" exec:exec 2012-04-09 09:00:00 5044km (machin) 2012-04-09 15:11:00 5651km (machin) 2012-04-09 21:33:20 8607km (truc) [... lots of output removed ...]
