* The table has a lot of fields that are only populated for MB, an not even consistently there. Do you use any of these fields for aggregation? Do you use this table at all when you do geographic analysis, or do you have a different one? They are all 255char fields, so if there are any we don't use we should consider eliminating them. There are also some erratic entries in there, eg. latitudes and longitudes missing their decimal points, or rhacode and province blank... do we need to review this?

** yes I use the table  and particularly helpful for MB where the RHA are listed.  i do not use the latitudes or longitudes.  if occupying more space, one option is to separate the MB from the rest.  maybe save the rest to another accdb but  keep the MB.  besides, new postal codes often occur at WPG/MB.  ---[[User:JMojica|JMojica]] 09:44, 2022 August 11 (CDT)

*** How about the CA, CA_Name, NC, NC_Name columns - do you use those? If you use the table we will just keep it in there, but I might still reduce the field sizes, they don't need to be 255. [[User:Ttenbergen|Ttenbergen]] 10:52, 2022 August 11 (CDT) }}

If Pagasa is the only user of this table we could move it into a different file, which would just have to be added to the push pull and reconnect machinery for Pagasa.

Revision as of 11:03, 2022 August 11

As of 2022-08-10 Centralized data.mdb was 1.348GB . This is large and slowly approaching MS Access' 2GB limit. The size also makes it slow to copy down, and even slower to copy up. This page is about attempts to make the file smaller.

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.mdb.

Next Steps

  • after Pagasa has legacy local, remove tables from Centralized master.

Postal_Code_Master table

There is a Postal_Code_Master table in Centralized data.mdb. It’s in this file because Pagasa maintains it, so if it was in CFE it would get lost if Tina made an update to that file. Removing this table would further shrink the file to 0.721GB .


  • Do you actually use this table? If so we might need to keep it in Centralized so you get any updates Pagasa makes. Ttenbergen 16:38, 2022 August 10 (CDT)
  • The table has a lot of fields that are only populated for MB, an not even consistently there. Do you use any of these fields for aggregation? Do you use this table at all when you do geographic analysis, or do you have a different one? They are all 255char fields, so if there are any we don't use we should consider eliminating them. There are also some erratic entries in there, eg. latitudes and longitudes missing their decimal points, or rhacode and province blank... do we need to review this?

Next Steps

_after

  • Waiting for info from Julie:
    • Can we move the file out? Ttenbergen 16:38, 2022 August 10 (CDT)
