How to Model Permissions on Use Case for Actors
In use case diagram, associations between actors and use cases are explicitly shown. We can see it clearly when an actor carries out a use case (or goal) from a line drawn between them. However, what if an actor does not carry out a use case but do refer to the output from it? How do we model that?
How to Import Microsoft Visio Stencils
When drawing UML diagrams (e.g. use case diagram), sometimes you might find yourself in a place where you could use other non-UML shapes, in order to explain the concept better. That’s why we made a collection of predefined stencils available for you. You can even import stencils from Microsoft Visio.
This tutorial will show you (1) how to use predefined stencils that come with VP-UML and (2) import stencils from Visio to VP-UML.
Create and Access Logical View via API
Open API not only allows you access the model data within the project, but also create and access the Logical View in your project. This article will show you how to create Logical View using Open API. Read more
How to Find Out What Version of SQL Server You Are Using
Visual Paradigm supports data modeling with ERD and a set of engineering features like the reverse engineering and generation of database. The features are related with each other. For example, you may generate a database from physical ERD. In order to construct a data model that helps you build a database properly, you need to name the entities and their columns properly. Besides, data types of columns should be well-considered. Just to take the type ‘char’ example, there are quite a number of similar types like varchar, varchar2, nvarchar, etc. If a wrong type is chosen for any column, you may get data corruption or result in data lost.

Visual Paradigm supports all the data types you can find in any supported database management system (DBMS). You can select any data type you want for columns when drawing ERD. As the supported data types vary depending on the target version of DBMS, you need to set in the database configuration page the version of DBMS you use. With this, Visual Paradigm can list out those supported types, preventing you from selecting a non-supported type, which result in producing an inaccurate data model.
In this article, you will learn how to find out the version of your MySQL installation. Try to follow the steps get the information needed, and select the proper version range in the database configuration window of VP-UML. Read more
How to upgrade VP Server (Prior to version 5.3)
With the latest release of VP Server 5.3, you might choose to upgrade from your existing server. To migrate properly, one must follow specific procedures to carry over vital information such as the current repository and user accounts to the new server.

How to Simulate UI Navigation
During UI design, having screen mock-ups could give others a better idea as to what users would be looking at when interacting with the system. With Visual Paradigm’s products ( e.g. Visual Paradigm for UML), you can create mock-ups using user interface diagrams. Apart from static visual presentation, you may also simulate navigation between screens after publishing your project to HTML files.
Customize a Logical View to Display Your Own Folder Structure
By default you can navigate your way through a project via default views such as those offered by Diagram Navigator and Model Explorer. While these standard views are readily available at your disposal, sometimes you may want one that is tailored to your specific needs. Read more
How to Reverse C++ Source with Predefined Macros
Visual Paradigm for UML supports round-trip engineering on C++ source file. But when you reverse C++ source code into class model, you may receive some strange error message complain there are syntax problem in your source file. This probably caused by the predefined macros in your source code. This article will teach you what you should configure in order to reverse your source code into class model. Read more
