ChkDB

ChkDB is rule-based data checking software for Oracle, plus files that define rule-sets and data domains (tables/views to be checked). The software is a PL/SQL package and some SQL scripts. There is currently no GUI front-end. For oil and gas data, there are domains and rulesets for well-header, drill-stem-test, and seismic-inventory data.

Recent releases

  •  28 Jan 2004 01:18

    Release Notes: This release fixes a bug that caused errors when using early versions of Oracle 8 (or earlier). The database column CHKDB_RULE.COLUMN_TYPE_CNDO was renamed from COLUMN_TYPE_CND. Specifying the datatype of a column in a rule is now optional if the user owns the table being checked.

      Release Notes: In this minor release, the SQL generated for partial-foreign-key checks has been improved and a rule for the CHKDB_OGW1_DST_PERIOD table has been tweaked. A rule with no effect will now cause a row to be inserted into the CHKDB_RULE_ERR table.
