Reuse Constraint Parameters in SysML Parametric Diagram

/0 Comments/in /by

The Parametric Diagram in SysML is a restricted form of the Internal Block Diagram. It shows the mathematical relationships between its modeled elements. Wish Parametric Diagram you can precisely define the details of a constraint in your system. The Parametric Diagram cannot live on its own, it must be relay on a SysML block, typically is a constraint block. In Visual Paradigm you won’t need to re-create the constraint parameters when you elaborate the constraint block with Parametric Diagram. In this article we will show you how you can reuse the constraint parameters when modeling in Parametric Diagram. Read more

How to override operations form superclass

/0 Comments/in /by

Method overriding is a very common technique in object-oriented programming. It allows developer deliver specific implementation of a method in the subclass although it already defined by the superclass. When overriding a method the subclass replace the implementation in superclass by providing a method which exactly same as the one in superclass, i.e same name, parameter and also the return type. In Visual Paradigm you don’t need to redefine the operation in subclass to model the override. You can simply do it in one click inside the specification dialog. To override the operation: Read more

tomcat-thumbEntity Relationship Diagram (ERD) is a tool for model the structure of a database. It mainly consists of the entity (database tables) as well as the relationships between them. Unlike the traditional UML diagrams, the relationship in ERD not just indicate the entitles are related to each other, it also specifies which column(s) between the source and target entities are linked, which also known as the primary key and foreign key relationship. People often want to have the relationships stick to its associated columns. But instead of manually adjust the connection point for the relationship connector, Visual Paradigm can automatically do it for you.

/0 Comments/in /by

tomcat-thumbThe Visual Paradigm Resource Centric interface is a handy feature for user to create diagrams without the need to memorize the syntax of the modeling language. It automatically filtered what you can do with the model element you working on in the diagram. In recent release Visual Paradigm enhanced the Resource Centric interface to become the Resource Catalog, which further boost the usability of the Resource Centric interface and make your diagraming task even easier. By default you will be switched to the Resource Catalog interface. But just in case you have missed the switch you can follow the details in this article to change the interface to Resource Catalog.

tomcat-thumbVisual Paradigm support wide range of databases for user to model the data structure of their systems. Once the data model is done you can generate persistent layer source code in Hibernate and use it as the out-of-the-box data access layer for building your database applications. All the data types which covered by Hibernate are directly supported by Visual Paradigm. But what if your model involved some domain specific data type which not covered by Hibernate? In this case you can make use of the User Type property to model it. To model with non-supported column types:
