PLP-matching

Part of code utilized to match incoming CSV files to current values in the database

While functional in-context, the script does not function without incoming CSV data and matched SQL database caches. Examples may be added later to the branch to make in functional.

Fundamentally, this script iterates through current values within the LINCS database and compares the incoming combinations of header and value to what is currently present in order to identify, count, and make array values of both matches and discrepencies.
