Correlation

Following successful verification of the entity candidate list, CA Endevor/DB's Correlation facility performs additional quality assurance activities on the target system:

• Impact Analysis – Each entity in the candidate list is checked against the target system CCDB in order to determine which listed entities have been changed since they were last promoted from the source system. CA Endevor/DB's Correlation facility utilizes IDD configuration information to determine not only which entities have changed since the last promotion but also which related entities might be adversely affected by the promotion or prevent successful promotion. In this way, CA Endevor/DB isolates and identifies potential problems before any damage is done.
• Source Comparison – CA Endevor/DB's source comparator function can be used to further identify differences between separate copies of the same entity or system, line-by-line. This capability is especially useful when upgrading vendor-supplied application software, particularly if the original version has been modified by the user. Source comparison can also be performed as part of the standard promotion procedure to produce a full report of changes at migration time, or to merge source from parallel development activity.
