Summary

What is better, a generic solution or a specific one? Stefan Tilkov’s answer is “It depends.” He compares XML vs HTML, DSM-UML, Internal-External DSL, SOAP-REST, and others, outlining the advantages and disadvantages of each solution, showing that there is no certain answer to an architect’s quest to solve his problem, but there are some guidelines helping along the way.

    It was a very nicely put dilemma with good examples, congratulations!

    I found one important for me point missing there though, which is code maintenance. I do agree forcing a generic solution to a peculiar problem often results in extra tedious and unnecessary work. Sometimes when the choice is not so obvious I would also consider the fact a generic solution might save you a couple thousands lines of code. These lines might be easy to write but you will have to maintain them later. And if they are easy to write you might be tempted to have them written by a novice developer which certainly won't help the code readability. So maybe it would be better to have a hundred lines of clumsy configuration after all in such case?

    Really like the presentation

    "It depends.." .. A truly generic answer :)

    Probably, a generic solution is merely a specific solution to a set of similar problems.
    Unfortunately, most of the time there is no definition for that similarity.

    I have always found the generic home build frameworks much harder to read, test and debug than the specific and perhaps boring solution.
    Even worse is the specific and undocumented configuration DSL that you invent for your generic framework. It might work for you but 'then come the next guy'.
    I would say go for the safe solution, the solution that you know will work. Boring code is very quick to write, it's the thought of repeated work that is hard to cope with. Then when you have a working solution, look for patterns, refactor and generalize.
    I would worry more about the novice architect than the novice developer.

    the app framework of devexpress www.devexpress.com/Products/NET/Application_Fra... is a perfect example.
