VCDB23

VCDB23 is the 2023 iteration of my venture capital database. The last previous build was VCDB20, and this follows the same basic design. This build was partial - not all location data was included. It was superseded by VCDB24.

Processing Steps

1. Copy over the rpt, ssh, and pl files, and bulk edit the ssh files, now in E:\projects\vcdb23\SDC.
   1. Change 12/31/2020 (and one 07/20/2020) to 12/31/2022 and vcdb20 to vcdb23
2. Run the ssh files against SDC Platinum. Note that SDC Platinum's service will be withdrawn on 31 December 2023.
3. Run the SDC Normalizer script (one of the pl files) on each output
   1. Fix the header row in USFirms1980.txt before normalizing (the Capital Under Management column name is too long)
   2. Remove double quotes from USFund1980-normal.txt, USFundExecs1980-normal.txt, USPortCo1980-normal.txt, USFirmBranchOffices1980.txt
   3. The private and public M&A file sets have to be separately combined into 2 files after they've been normalized. Then replace \tnp\t and \tnm\t with \t\t in each.
   4. For RoundOnOneLine, remove the footer, run NormalizeFixedWidth.pl first, then RoundOnOneLine.pl, and then fix the header.
   5. PortCoLongDescription must be pre-processed from the command line and then post-processed in excel (see VCDB20H1 and Vcdb4#Long_Description). However, I didn't load it for this run.
4. Create a new database on mother (createdb vcdb23) and setup a directory for the input files: E:\projects\vcdb23
5. Copy over and edit Load.sql. Run it section-by-section.
