Reverse engineering strategy based on the "remarks" property of the database tables and fields

Reverse Engineering from a Database to JPA Entities based on the Remarks

Description

Reverse engineering strategy based on the "remarks" property of the database tables and fields.

The transformation rules applied to the remarks are:

+------------+----------------+-------------------+
|   Remark   | Table to class | Field to property |
+------------+----------------+-------------------+
| the remark | TheRemark      | theRemark         |
| the_remark | TheRemark      | theRemark         |
| theremark  | Theremark      | theremark         |
| theRemark  | Theremark      | theremark         |
+------------+----------------+-------------------+

If no remark has been set, the corresponding table/field real name will be used to proceed the transformation.

For example, given the below MySQL table named "tbl_user" with the comment "user":

+----------------------+--------------+-----+-------------------+
|         name         |     type     | ... |     comments      |
+----------------------+--------------+-----+-------------------+
| id_user              | int(11)      | ... |                   |
| tx_email             | varchar(100) | ... | the email         |
| tx_username          | varchar(20)  | ... | userName          |
| tx_password          | char(40)     | ... | password          |
| bl_need_confirmation | tinyint(1)   | ... | need_confirmation |
+----------------------+--------------+-----+-------------------+

The following entity will be generated:

public class User {
	
	private int idUser;
	private String theEmail;
	private String username;
	private String password;
	private boolean needConfirmation;
	
	// ...
	
}
