Changes to make Centralized data smaller

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.

Log

• 2022-08-10:
  • emailed Pagasa to copy Legacy to local
  • updated CFE re-link to these in Legacy_TMS_Data.mdb rather than in Centralized data.mdb
  • emailed Julie and confirmed we should do this
  • imported L Dxs table and L Como table into Legacy TMS Data.mdb as version 2022-08-10
  • Julie copied the Legacy_TMS_Data.mdb to local where SAS will pull from (08Aug2022 )

Postal_Code_Master table

There is a Postal_Code_Master table in Centralized data.mdb. The table is likely in the correct file because Pagasa maintains it and Julie uses it.

When extracted to its own file, table is 89MB

Discussion with Julie established that she doesn't use the following fields, so eliminating them: latitude and longitude, so

_after reduce field sizes as much as possible do some quality control remove latitude and longitude

... yes I use the table and particularly helpful for MB where the RHA are listed. ... ---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. Ttenbergen 10:52, 2022 August 11 (CDT) I think I have used it when asked where from winnipeg area patients come from but very rare. - --JMojica 11:03, 2022 August 11 (CDT) Do you use the code and name fields for them or would you be OK if we use the code fields?
