Data quality and validation
Posted on 2012-04-12
I need some form of audit checklist for data quality and validation. We have hundreds and hundreds of lines of rows of data in an access database that seems to be a complete mess when it comes to quality, data in wrong fields, missing data, inconsistent data etc. There is no application front end that controls the input of data, and there appears to be a multitude of ways that the data has ended up in the tables in the database (including manual typing). I need some sort of data quality and validation audit benchmark to say the way you are doing things is hopeless, here is a set of controls or best practices to prevent this happening again. I just want a document with “here’s control 1-15 on how to manage this to ensure data quality and useful data”.
