What are the best practices for database development with Delphi?

Question

1. How can I use the RAD way productively (reusing code). Any samples, existing libraries, basic crud generators?
2. How can I design the OOP way? Which design patt

Answer 1

Use VFI (visual form inheritance). Design a standart DB form. For example, empty DataSet, DataSource, a PageControl consisting of 2 sheets. First will be empty, later on you'll add edit controls to manipulate data at child forms. Add DBGrid to the second sheet. Beware, this isn't the OOP way though, but it's easy and fast.
