A bunch of us engineers working on SQL Server would like to learn more about real-world experiences and challenges people have with databases. We would love to hear from startups building cloud applications who don’t use SQL Server -- we don’t often get feedback from this segment of users.
We are not selling or marketing anything – just engineers who would like to listen about what you like and don’t like about databases that you use and the challenges you have to deal with.
