Increase Heap Size to Prevent Out Of Memory Print

When running Visual Paradigm products, you may receive a message that asks you to increase the memory size in order to complete an action, e.g. generate report for a large scale project. In such case, you need to increase the heap size of the Java Virtual Machine (JVM).

Hibernate User Type Support Print
Visual Paradigm's ORM code generation has high flexibility. One example is to let users to define their own data type to handle meaningful data conversion in type level. There are two ways for type definition, which involve extending type classes with <<ORM User Type>> and <<ORM Parameterized Type>> stereotypes. In this article, we will go through the two ways of defining and implementing user-defined types.

The support of database sequence is now ready. User can now model the sequence in an ERD by creating sequence model(s) and filling in the necessary information needed in database generation.

Automatically Filled Column Type Print
Adding columns to entities can be a tedious and error prone task. For example, we may have created a “NAME” field on both entity A and B, but mistaken, one is set as varchar(100), while another is set as varchar(200), which leads to inconsistency of model and affects the data storage. Visual Paradigm provides functionalities to make the creation of columns flexible and accurate, which include the support of shortcut key, the ability to copy columns across entities, etc.
 
Automatically Filled Attribute Type Print
Adding attributes to classes can be a tedious and error prone task. For example, we may have created a “gender” field on both class A and B, but mistaken, one is set as boolean, while another is set as integer, which leads to inconsistency of model and affects the implementation. Visual Paradigm provides functionalities to make the creation of attributes flexible and accurate, which include the support of shortcut key, the ability to copy members across classes, etc.
