We all want to stay ahead with technology, using the latest trends in the programming world to have a better technological background and consequently land cool jobs. Some people tend to write applications, keeping this idea in mind. Let's explain this scenario using the application example for manipulating log files that we mentioned in the previous section.

Suppose you're asked to solve the problem that we mentioned in the I know my land section. In this scenario, your only concern is technology. For instance, let's say you want to try the newest features in the latest PHP release. In this case, you will build this application using PHP. While this programming language has been improving over the last few years since Facebook started to add new features to it, the idea behind writing an application to manipulate large log files using PHP is crazy. As you may know, this programming language is intended to create other kinds of applications—mainly those that have to be accessed using a web browser and without high transactional requirements.

Again, you can write an application using PHP to manipulate large log files, but what will happen when more features are needed? Do you think a software architecture created with this approach in mind will be able to respond quickly to new requirements and the inherent characteristics of the application used in this example?
