Data Extraction from NNEREN MLS Listing Database

Implemented a PHP script to run as a scheduled cron job to extract latest MLS listing information from NNERENs database views. The script intelligently extracts data from MS SQL server views provided by NNEREN and then dumps it into a MySQL database. The challenge was to minimize the amount of data transferred for each update which was exhausting process memory limits as image data for real estate property listings is also stored in the MS SQL database.
