With a sophisticated design surface that supports both model first and database first approaches you can work exactly how you want without having the tools get in your way. The LightSpeed designer is available as part of every edition of LightSpeed. See their website for a free fully functional trial of their Express Edition. See www.mindscape.co.nz for downloads.
