It's a generator that creates UML diagrams automatically from the source code. This lead us to develop our custom solution to the problem. For a long time we drew them by hand, but obviously after some time most of them were no longer up to date. In the first phase we want to provide a class diagram with all the design pattern examples. Since the project is mainly aimed at architects and developers, it is natural that the documentation contains also UML diagrams. We have recognized this problem in Java Design Patterns project. The other quite popular alternative is to skip the documentation updates and accumulate technical debt in form of stale documentation. Required documentation changes may take as long or even longer than the source code change and testing. The documentation may have been written by someone else and the developer needs to read everything just to get to know what needs to be updated. With any non-trivial project containing decent documentation this quickly becomes a nuisance.

In an ideal world the documentation would be revised every time the software changes. Software changes rapidly and it's hard to keep everything updated.

Documentation is good only when it's up to date. The problem with documentationĭocumentation is good and more is better, right? It quickly turns out that it's not so black and white. These are excellent industry standard tools to quickly convey large amounts of knowledge about program design. The most commonly used UML diagrams include: If everything does not fit in there nicely, just include the links to the subpages.įor topic 3, Unified Modeling Language (UML) provides tools to describe software design and architectural blueprints in visual manner. Nowadays it's good practise to put all this information in the project's README.md file.

What features will be developed next and how to contribute.

What is it and what problems does it solve.

The project documentation needs to fulfill many purposes, but the minimum set that any significant program's documentation should answer consists of the following: The developers are additionally interested in how it works. The users of the software are typically concerned with how to install and use it. The needs are a bit different depending on what he wants to do with the project, but the common ground is to grasp a high level understanding. The main classes of the Railway Reservation System are Train, Ticket, Booking, Customer, Payment, Train Route.Often when a person is starting to get familiar with a new project, the first thing he wants to see is the documentation. Railway Reservation System Class Diagram describes the structure of a Railway Reservation System classes, their attributes, operations (or methods), and the relationships among objects.
