I completely agree with dvz's comment.<br />
While working at one of the top transportation companies, we had Erwin to work with.<br />
Even if it is an exceptional product, I recall we (IT Group) never used more that &nbsp;5 - 10% of the functionality, in fact, for quick and dirty designs everyone used Visio.<br />
<br />
Good luck!<br />
:p

Greetings Experts,<br />
<br />
We are looking at purchasing a data modeling system for our organization. &nbsp;I have seen in past posts the most recommended systems are:<br />
<br />
PowerDesigner<br />
Oracle Designer<br />
CA ERWIN<br />
<br />
However, I have been able to find information from the developer's site for things such as:<br />
<br />
Scalability<br />
Flexibility<br />
Maturity<br />
User friendliness<br />
Platform Dependency<br />
Limitations<br />
Who has the market share (who is the best)<br />
<br />
Any help in answering these questions would be great.<br />

IBM DB2 is a family of relational database server products developed by IBM that have been extended to support object-relational features and non-relational structures like JSON and XML.

Oracle is an object-relational database management system. It supports a large number of languages and application development frameworks. Its primary languages are SQL, PL/SQL and Java, but it also includes support for C and C++. Oracle also has its own enterprise modules and application server software.
