BU Comparer.accdb

From CCMDB Wiki

BU_Comparer.accdb is a tool to compare the backups on the regional server to Centralized. It is used for main office forensics.

This file should only be open while there is a reasonable expectation that no one will back up.

For now the master lives on Pagasa's PC.

findings so far

Turns out they are all missing stuff. Not all of it, and I still don’t understand the pattern.

L_..._BU_all queries

The L_..._BU_all queries (e.g. L_CCI_Component_BU_all) contain the entries of all instances of that table in the backup files. They make up D_ID equivalent columns (BU_Pat_ID, BU_

_ID) to enable linking to the corresponding CFE tables.

Compare... queries

The compare queries (e.g. Compare_CCI_Component_BU_all) compare the contents of the current backups to the contents of the copy of Centralized_data that lives in the same directory. The columns should be the same for RecordStatus = Sent. For other RecordStatus the backup may have been made some time after the last sent, so they may be different.

Utility functions

There is a sub connect_backups() that will link in all backups to this program.
