Hi James, There are many different ways to do this, and it may or may not be necessary to access the database at all.
Really any scripting language can be used to automate tasks. Some of the ones which I know are being used are Bash, NodeJS, Python and R. Likely there are others out there. There is no requirement to have a Java executable by any means, but it of course could be done this way, if you were so inclined. Anything which can interact with the WebAPI using HTTP should be fine. Here is a good example in NodeJS- https://github.com/dhis2/dhis2-utils/blob/master/resources/nodejs/integrity/integrity.js of a task which checks some special Integrity SQL views, and then sends out a notification if any of them fail. The basic pattern though is to access some enpoint through the API, process what you need in your script, and possibly post something back to the server. The other way, as Pierre points out, would be to call an SQL view with a cron job through the API, but It would seem not to be really what you want to do, if you do not want to use PgAgent, which could do the same thing.
