Why Isok

Lots of reasons.

Isok can help you manage your data's integrity, especially when little technical effort can be spared or manual review is involved.

Isok may be for you if you are involved in data cleanup, or data integrity maintenance, or don't want to put your data monitoring into an app or otherwise design something, or are tired of re-examining the "problems" your queries report that you have determined are not really problems.

Isok makes practical the monitoring and management of unusual, but sometimes allowed, data patterns. And it assists with the management of problem resolution over time.

How Isok Works

Isok is a PostgreSQL extension for monitoring anything that can be reported with an SQL query. Unlike simply running a query, which reports the existence of questionable data patterns, Isok produces reports alerting you of changes to questionable data patterns, so that only new problems need be reviewed.

To use Isok you write SQL queries, which produce reports alerting you of questionable data patterns. Then, on a row by row basis, you can defer, possibly forever, the appearance of individual alerts on future reports. Isok includes record-keeping and scheduling features to assist with problem resolution.

Requirements

Isok installs on PostgreSQL version 10 or later, although PostgreSQL versions no longer supported by The PostgreSQL Global Development Group may not get support.

Isok can be built as pure SQL, for installation in the cloud or other managed PostgreSQL instances.

Downloads

The recommended download is from the pg_isok page at PGXN.org. (Look for Green circle containing a
      down-pointing arrow, a little green circle with a down-pointing arrow, in the upper-right area of the page.)

It is possible, but not recommended, to build from source.

Installation is required.
