First let me write the context.
I'm a programmer and lately I'm working with PHP and MySQL. But sometimes I work with SQL-Server. Normally I work with many computers (office, main office, laptop, etc). The only "common" thing in these computers is ... they have Internet connections.
To develop a database (nothing too complicated, 15 tables at most) I have to wait to be in my office.
In fact, I'd like to develop the solution (I repeat, simple solutions to simple problems) from any place.
All my "developments" ara targeted to the web.
Do you know any "online tool" to create the database? CRUD capable? Best of all, can I program it online?
Must follow the Entity-Relationship paradigm.
May be this tool does not exist because is too generic. But I want to use it por simple projects. For real projects I can use SQL Server or MySQL. I need something may be simple, but strong enough to "show" basic protoypes.
