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). |

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.

When generating ORM code, we can specify the way of how error is handled, like this: |
The SQL statements generated from Visual Paradigm can be set to appear at upper or lower case. To set as upper case, select Upper Case SQL in the Database Code Generation dialog box (Tools > Object Relational Mapping (ORM) > Generate Database...):

By default, the SQL statements generated are unformatted. However, it is possible to format them by checking the “Format SQL” option in database generation. In this article, we will see how to generate formatted SQL statements. |

When synchronizing an Entity Relationship Diagram to Class Diagram, user can set how numeric and decimal data types will be mapped to object model. We will go through the key concept in this article. |
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.

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.

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.
