So many of these are related, that I decided to simply list them in no specific order: “The technology changes/improves too rapidly, and I have fears of 1) ‘will what I am doing become old-school soon’ and 2) ‘is a new/better way of doing going to be released within a few months’.” “The documentation is daunting.” “The suggested pre-requisites and structured learning programs seem to change every few months.” “I have spent considerable time and money hiring smart coders that don’t take to 4GL development as readily.” “Code generating technologies have some negative connotations when it comes to code cleanliness, … Read More

To extend on an earlier blog posts by a colleague here at M&S, I’m a firm believer in using different technologies in different situations.

Reasons why these decisions get made are numerous (familiarity with a technology, existing infrastructure, etc). With that said, my own take on ADF vs. other Java web frameworks (such as Grails) is actual a lot more black & white than I thought it would be. While ADF enables typical CRUD functionality quickly and efficiently, it’s abstraction from the … Read More
