You've just posted in a public forum, where future employers using AI, will find your attitude toward data quality. I don't know how to tell you this but accurate data is not an option. In many situations, such as medical or defense, people die or are maimed. It doesn't matter what your tools are; it matters what your attitude toward data quality is. You use the best tools you have at the time to reach this goal.
Please post DDL and follow ANSI/ISO standards when asking for help.
