If you do not know what ERPs are, we now know why you have not gotten a job interview offer from those companies you applied to. ERP stands for Enterprise Resource Planning. An easier way to describe ERP is simply a business software. There are a great number of ERPs, such as Oracle, SAP, MS Dynamics, Salesforce, Quickbooks, Dayforce HCM, and many more. Those companies who offer data analysts / scientists positions use ERPs because an ERP is THE system that produces such massive datasets for the data scientists to analyze. Study it starting today, or at least watch a couple of Youtube videos that explain ERPs.
