TierDeveloper

I have used TierDeveloper personally and I’m very much satisfied with the product. Here are some of the strengths and weaknesses of TierDeveloper(in my opinion)

Strenghts
Easy to use. Learning curve is around 1 hour.
Customization of the generated code is possible through TemplateIDE tool provided with it.
Advanced features like synchronization with the database, automatic creation of relationships, inheritance support, object binding support etc.
Very responsive support staff
Support for large number of databases
Include your own business logic through use of Custom Hooks
Import Objects from Assembly and XML File
Support for webservices
Generates fully working database applications for real-life use

Weaknesses
Documentation is not very detailed.
MySQL and Postgres support is missing.
