Much like a spreadsheet, TAB2APP is so flexible and general purpose. We can model and solve whatever problem while using its specific vocabulary and rules. We can build simple applications like a calculator, forms, report...as well as more complex systems.

All that without coding, unless you are not familiar with formula language :). If you had to develop such a software otherwise, you would spend thousands of hours specifying, coding, testing, debugging, reporting, deploying...not to talk about the cost!
