The PostgreSQL extension for CLIPS Expert System provides access to a PostgreSQL database from the CLIPS environment by exposing a number of CLIPS functions. CLIPS users who are familiar with SQL should not have much difficulty in learning how to use the additional functions to interact with the database from the CLIPS environment.
JobRunner is a tool designed to run a job (i.e., to execute a commandline or script) which does not require user interaction, and to store the program's output (standard error and standard out) in an easy-to-read log file. It is able to save a configuration file of the job to be run, which can be used by JobRunner_Caller as a lightweight queueing system. See the Primer included in the archive for extra details on usage examples.
