TRIMM JPA will leave table and column names up to the default JPA rules, unless you instruct it to specify @Table, @JoinTable, @Column, @JoinColumn, et, e.g. using the addTableAndColumnNames parameter in the JPA YAML configuration.

It can sometimes be useful to control the table and column names if the default names (which follows the JPA default naming standard) collide with database reserved words or if you use a “modern” database like Oracle which still limits names to 30 characters 😉

How to develop MDG’s for Enterprise Architect 9.x, part 3

Categories: Code Generation, Model Driven Development, Sparx Enterprise Architect, UML

Tags: ea, mdg, profile, sparx, technology, UML

Comments: No

Introduction

In the first tutorial, we looked at how to develop the TrimmWS Profile containing the Web Service modeling elements for use by the TigerTeam Trimm Model Generator and how to save it as a Profile that can be imported into EA. In the second tutorial we looked into how to make the Profile and its content more usable by combining it with a Toolbox and a Diagram into an MDG.

This tutorial describes how to add our own Datatypes to the TigerTeam TrimmWS MDG and how to automatically make them available to our modeling elements.

Generating code from UML can be very useful, although the usefulness of the result depends on what type of UML diagrams you use.

We’ve been part of several large projects where we used UML class diagrams to model the domain model, according to the DDD principles. Domain models (being OO persistable class models or Web service model) focus on structural patterns, i.e. how the different constructs (like entities, values objects, aggregate, etc.) relate to each other. For structural models we prefer UML class diagrams as we feel the convey information in a much better way than pure textual DSLs.

Visualization of relationships provides a better overview and is a good platform for communication.

Introduction

In the first tutorial, we looked at how to develop the Profile containing the Web Service modeling elements for use by the TigerTeam Trimm Model Generator and how to save it as a Profile that can be imported into EA. In this second tutorial we will look into how we can make the Profile and its content more usable by combining it with a Toolbox and a Diagram into an MDG.

Why do we want to combine those and introduce the MDG when the profile already seem to do the trick? The simple answer is ease of use compared to using just the Profile. By adding a Toolbox and a Diagram, we can make our Profile act like any other built in feature and make it a lot easier to use.
