I'm looking for a cloud based database solution where I can store about 1 GB worth of tabular data and both myself and my client can access to perform SQL queries. I'm looking for this database to have a simple Graphic User Interface that's intuitive to allow custom queries and to export results in a format such as CSV, DBF, etc. I'm okay with a monthly charge less than $50 per month.
I've looked at Amazon Web Services RDS, but I'm really confused how to "share" a MySQL database with my client. My understanding is that AWS RDS is a cloud based database solution where multiple users can access and manipulate data. It's sounding more like a database has to be installed on your local machine and a connection is then made. I'm not looking to download database software (ie MySQL), I just need the database and connections all to be in the cloud.
