SQL Queries - CAST Central Base - Queries on applications - How to get the TQI by Technology TQI by Functional Module or global TQI for a Snapshot

Purpose of Query

The Total Quality Index (TQI) is derived from a combination of the five health factors – Transferability, Changeability, Robustness, Performance, and Security.

You can measure it by technology, by functional module, or for the whole snapshot

SELECT dso.object_name               AS technology,
       ROUND(dmr.metric_num_value,3) AS TQI
FROM   dss_metric_results dmr,

Query result example

“JCL”;3.043
“Cobol”;2.324
“IMS”;3.584
“DB2 Server”;2.143

Query result interpretation

In Snapshot <SNAPSHOT_ID> of application <APPLICATION_ID> ,

  • The TQI computed on JCL objects is 3.043
  • The TQI computed on Cobol objects is 2.324
  • The TQI computed on IMS objects is 3.584
  • The TQI computed on DB2 Server objects is 2.143

Get the TQI by Functional Module

SELECT dso.object_name                AS module,
       ROUND(dmr.metric_num_value, 3) AS TQI
FROM   dss_metric_results dmr,

WHERE  dmr.object_id IN
       (SELECT dli.next_object_id
       FROM    dss_link_info dli

AND    dmr.metric_value_index = 0
AND    dmr.object_id          = dso.object_id

Query result example

“App1 full content”;2.221

Query result interpretation

In Snapshot <SNAPSHOT_ID> of application <APPLICATION_ID> , the TQI computed on module “App1 full content” is 2.221

In this case, (full-content module), it is the same as computing the TQI on the whole application. For an example with several modules, see Oracle example.
