As of 2022-08-10 Centralized_data.accdb was 1.348GB . This is large and slowly approaching MS Access' 2GB limit. The size also made it slow to copy down, and even slower to copy up. We made some changes to reduce the size by #Removing the L_Dxs table and L_Como table and #Reducing fields and field sizes in the Postal_Code_Master table. This initiative is now complete.

Removing the L_Dxs table and L_Como table

We can reduce the file size to 0.810GB by moving the legacy tables L_Dxs table and L_Como table to Legacy TMS Data.mdb. These tables are “stale” and no longer change, so we don’t really need to have them in Centralized_data.accdb.

Log

Reducing fields and field sizes in the Postal_Code_Master table

There is a Postal_Code_Master table in Centralized_data.accdb. The table is likely in the correct Access file because Pagasa maintains it and Julie uses it.

Log

  • removed "code" fields that duplicate "name" field data, and reduced field sizes as much as possible, which reduced table size from ~89MB to ~70MB.
