Why data updating is important
Heck, data management even made it into the US State of the Union Address.
In a purely designed database these values would be divested into an extra entity or Reference Table called 'status' in order to achieve database normalization.

With all these questions about data model coming in, I thought I’d answer the most common ones here so that I can share them more widely. Often when I’m hired as the sole architect, I’m swamped with real work and no one has time to be trained nor is there time allocated for me to train anyone. If they specialize, really, in data modeling, it may be worth it. I want to warn you that hiring a data architect that really is one is difficult.Tags: Adult Dating, affair dating, sex dating
