In Python, instead of having a separate hasNext and next method (not to mention all the extra methods), it just has one for getting the next item and throws an exception if there are no more items. The real insight from FP is that you rarely even need more than a couple of methods which can be passed in as individual arguments (honestly couple is being generous, most interfaces really only need one method).Ĭompare how complicated implementing an Iterator is in Java vs Python. I don't know, I find that UML often results in huge complicated interfaces. The only bad thing about that project really was that we were using CVS to store the code.

You make your RR change, run a script, and then all you need code is the business logic. As long as you know class diagrams and have a basic understanding of Rational Rose, making changes to the database structure and the code that supports it is pretty quick & easy. Curam, an Irish system created by Curam software, takes output from Rational Rose, where you maintain a class diagram, to produce the database tables and the entity classes you need for the system. One system I maintained for a while was the Curam based Jersey & Guernsey benefits system. That can be very useful - if you know UML and you want a quick way to understand an existing system that you're going to extend or refactor, having a quickly-produced UML diagram can get you there pretty easily. On the other hand, there are addons for some IDEs that will create UML diagrams from existing code. You don't want to take an hour or two diagramming a design only to find that the diagram is obsolete in 5 minutes. The problem is that it takes a lot of investment in time to learn & produce good UML diagrams & if you're doing Agile programming, your designs need to be easily changeable. You still see it occasionally on governmental projects, but it's rare. Just loads of spaghetti core from decades of java development. There was no architecture, no common sense. A complete nightmare because you had to have experience.

The last time I had to start in a team, working on an application, I would find the button I wanted to press and then drill my way through by searching for the text of the button in code and then to whatever part I was looking at. I was able to work for myself in like five minutes and was able to do a lot on my own. When I started with them, he gave me like two UML diagrams for our micro services architecture, a sequence diagram for the current service I was to work on once I had installed my machine, and a few other services to take notes from. Or documentation! My team has had a great tech lead (just a regular team member who is also tasked with having a look on used tech (we change things up quite a bit), who does research, asks for other people to do research) and keeps an eye on the technical aspects of the services.
