为Android设计SQLite数据库的开发工具

I'm fairly new to Android, I'm trying to create a rather complex app (something more advanced than notepad or task reminder), with some serious underlying data model. I'm using Eclipse with the Android SDK plugin, everything is working well. But what should I use for database design? I've gone through some sample apps that create databases programmatically, but those only contained a single table with a few columns. What I want to create is a database with multiple tables, private key/foreign key constraints, enumerations and all that jazz. If I had to do this manually, I'd probably go grey by the time I'm finished. I've designed quite a few databases in my time, be it in MS Visual Studio, MS SQL Server Management Studio, Oracle DB Designer and similar tools. I realize that SQLite doesn't have some fancy shmancy DB server where I could run SQL scripts and it would create the database and keep it alive. I know it's all part of the application and the app itself must create and maintain its database. Is there any visual DB design tool, which I could maybe integrate into Eclipse (not necessary) and which would, I don't know, generate the database creation code, so that the database would be usable in my application?I'm fairly new to Android, I'm trying to create
