alt Hacker NewsA big software for simulating the economic balance sheets of life insurance companies moved many years ago from using FoxPro under the hood to CSV files and sold it as a huge improvement. I don't think anybody was convinced by that, but vendor lock-in makes companies accept such regressions.
I was on a project trying to migrate off Oracle and they wanted to just dump all historic data to CSVs.
I pointed out they'd lose a lot of the integrity and audit features built into a database.
I get wanting to be free from Oracle but go to another database.
