Is there a future for Informix 4GL applications?


A lot of companies using Informix 4GL have been questioning for some time about the evolution of their applications. Should they cancel them and replace everything with a new technology, since IBM competition pretend that anyway Informix doesn’t exist anymore? Should they maintain them “as is”, since after all they fully satisfy their requirements? Are there other alternatives? Do they bring a real added value, or are they just a temporary solution?

You will find in this article a number of elements of a response that should contribute to build a solution based not on information coming from this or that marketing department hunting for new clients, nor slideware or vaporware technology, but on objective analysis and proven facts.

Taking the wrong path must be avoided: the consequences of such a decision are too important for final users adoption, but above all for the correct operation of your activity. The risk involved,  combined with likely budget slippage, can produce highly explosive conditions that must be handled with all the appropriate care.

    Hey there Eric; nice article. I hope you don’t mind me quoting several lines of this article to talk to my clients. I will definitely translate it to Spanish as soon as possible and post it on our website. It was very nice to meet you in San Diego. Greetings from Mexico.

    Hi Eric,
    I have been reading your articles and you are making a great Job for the Informix Community. Thanks for this. In my company we are focussed on developing new Applications in Genero BDL and converting Informix 4gl to Genero BDL. Four JS is giving us great new features in every new Version they provide. We are also making our first steps with Genero Mobile which shows already in the early access program great capabilities. So before “throwing away” the old Informix 4gl applications consider Genero BDL.
    Greetings from Germany.

      Olá Daniel,

      thanks for the comments. Regarding the technology, I have made my choice years ago upon recommendation of other 4GL “gurus” which all went to the same direction: the Querix technology is more advanced, extensible and more open to modern techs than ‘the other one. Also, in a migration from Legacy to Querix, you don’t have to modify the 4GL code to have a more modern rendering, you will work on the forms, which avoid breaking any working logics in 4GL … ( and also faster )
      I won’t speak about the budget which is also much lower, be it for the IDE as well as for the runtimes.
      You should really take a look at Lycia 🙂
      Happy New year
