ColumbusEgg4Delphi is...
A simple to use Delphi framework to correctly write business logic in Delphi "RAD style" applications.
Based on Table Module design pattern but adapted to be Delphi friendly and dataset centric.
Provides all the good alternatives to do the common Delphi practices which makes your application hard to test, in a testable way.
Provides observers and listeners to avoid all the business logic code in your form.
Retain almost all the good of Delphi RAD.
Developed by bit Time Professionals.
Why ColumbusEgg4Delphi?
Forms and datamodules are free of Business Logic code.
Provides a single point for the BL code
You can do unit tests; Business Logic can be unit tested using in-memory datasets.
You can still use the RAD approach to design you forms
If your data comes from an application server, you can fill in-memory datasets (or virtual dataset) and still use the same Business Logic.
Very Important!
Columbusegg4delphi can be used also in legacy applications to improve their architecture at very low cost.
Just create a columbus module for each dataset and move there all the events related code. It is an incremental approach; you can change it one dataset at time.
