I have used phpmyadmin, but that's not the only option that I have.
Me explaining the other option would be like me talking to a dog. Sometimes I speak with dogs, and they do what I say. Their level of intelligence is not high, so they listen to me, and I speak in a childish way to them. My point is they won't understand me if I speak differently to them. I don't think they would care, and maybe they might walk away from me.
I am really sorry, but I think your team is setting up, for failure.
I realize non tech people want to use something to manage a database that's easier than phpmyadmin, but don't you think that's a stupid decision to make?
In other words I think you are trying to put the wrong person, or people in charge of something that he, or she doesn't understand.
Frankly I don't care if the startups falls apart, and yes, I can imagine it falling apart.
I am going to try to be nice. and say whoever wants to manage a database that's part of your team should put a cone on his, or her head that says stupid on it.
I think you noticed how I am speaking with you right, but what I am not doing is speaking in a way that you want to read, and are able to understand. Because that's not realistic. FYI....I am holding back, so hopefully you can understand me.
If I meet someone who can challenge me then I will speak in a different way, and it won't be like how I am speaking here.
