How to Share Stereotypes Definitions?

/0 Comments/in , /by

Share stereotypes thumbnailStereotype is an extension mechanism you can use to define new model elements. In Visual Paradigm you can apply stereotype on both UML and BPMN elements.

With the import/export stereotypes utility, you can easily share stereotypes’ definition with colleagues without having to re-configure them again from scratch. If conflicts are detected when importing stereotypes, you can select to resolve them to ensure important configurations are not accidentally overwritten by other team members.

How to overload operations in class model

/0 Comments/in /by

Overloading methods is a very important technique in object-oriented modeling. It offer the ability to create multiple operations of same name with different implementations. In Visual Paradigm you can overload the operations simply from its specification dialog. To overload the operation: Read more

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

Why the relationships between entities not point to FK column?

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.

Switch from Classic Resource Centric Interface to Resource Catalog

/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.

Model Entity with Custom Column Types

/0 Comments/in , , /by

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:

Specifying details for your association

/0 Comments/in /by

Association is a very comment relationship between classifiers. The association is not a simple connector, it carry lots of information related to the relationships between classifiers. Those information may/may not presented on diagram, but they are vital to the definition of your models. In Visual Paradigm there are several ways to define the details for your association and in this article we will show you one by one. Read more

How to create different notations in a single diagram

/0 Comments/in /by

Visual Paradigm supported modeling with various notations, including the Unified Modeling Language (UML), System Modeling Language (SysML), Business Process Modeling Notation (BPMN), Entity Relationship Diagram (ERD), Data Flow Diagram (DFD), Organization Chart, etc… When creating diagrams very often you may want to cross reference the notations from other diagram type, or even from other notation standards. In Visual Paradigm you can do it easily by customizing the diagram toolbar. In this article we will show you how it works. Read more

Show Details of Model Elements in Tabular Form

/43 Comments/in /by

When the default attributes do not suffice to describe your model elements, you can add your own custom ones by using tagged values. These custom attributes can be added to model elements in various diagrams, such as an actor in use case diagram.

So if you are looking at model elements in a diagram, just how do you show their tagged values? This tutorial will show you how.

As an example, we will walk you through how to show tagged values associated with devices in an ArchiMate diagram.
