NavalPlan<\/a> is a Java<\/em> application built using Object Oriented Programming<\/a> and whose data are stored in a relational database – currently PostgreSQL<\/em> and MySQL<\/em> are the RDBMS<\/em> supported and tested-. To map objects from the objects models to relational tables the Hibernate<\/a> ORM<\/a> is used, which is a well-known framework in Java<\/em> platform widely deployed.<\/p>\n

In the business layer, it is applied the Domain Model<\/a> architecture pattern which briefly consists of having rich business objects which encapsulate in the same class the data and the behavior related to them. I think that it was a good decision and I am happy with it. Among other advantages, it allows to organize complex behavior and to reuse business logic easily.<\/p>\n

The NavalPlan<\/a> domain model is large and complex, and one of the problems is its maintenance from documentation point of view. This is so because to have UML diagrams<\/em> updated is time consuming.<\/p>\n

To address the problem above and to have some nice diagrams to teach NavalPlan<\/a> to new developers, I have being playing today with a tool to infer UML class diagrams<\/em> from the Hibernate mapping files. With a tool like this a lot of time would be saved !!<\/p>\n

The tool I found is Linguine Maps<\/a>. You have to develope a program to use it but, after resolving some configuration issues, I got a quite good result. Therefore, we will use it in NavalPlan<\/a> from now on.<\/p>\n

With Linguie Maps<\/a> you can configure several things and create diagrams just with the classes you are interested in. As an example and to view a whole picture of NavalPlan<\/a> I generated a chart with all the classes. I know that maybe it reminds you of an Indian war with so many arrows, but I think that it could be got a good poster from it \ud83d\ude09<\/p>\n
