I’ve talked about this before, but I think that it’s worthy enough to talk about it over and over again. When developing in Oracle Application Express, we want to make things as simple as possible. Even if it’s only because it give you the room to develop with multiple developers, develop a large and even complicated application in an extremely short amount of time and maintenance costs will decrease after the application is taken in production.
In one of the projects we recently released into the wild, (in fact I do this on all of them, but this is a good example) we developed not one, but multiple small applications that get tied together. For every application you develop you will need not one, but at least three applications. The Front- and Back End and the Lay Out application. Using such a modular approach, gives us a lot of advantages, and time isn’t the only one.
Because now we have one part of the application that is published outside the companies walls we can more effectively secure this, and the other, applications. Because of the fact the we have one application that only serves as the lay-out development platform, we can easily make changes that won’t affect the rest of the development team. When we are developing in this way we can work with smaller teams of developers on one application. We can make more specific changes to an application as it will not affect others.
It is so simple, yet I still encounter APEX applications that are build in just one app. This strikes me, because it makes the live of developers very complicated. Especially because all applications get more complicated along the way.
