Dear Sir or Madam,

Awfully formal! I case you hasn't noticed this is a mailing list and everything said is public record, I expect you know that already though

 

Because of my bachelor thesis I´m searching for a visualization-tool that is able to create entity-relationship-models (ERM). Current data is saved as an .xlsm-file – in a structure that not like an expected format for ERMs. Simply a connection between data and shapes would be possible with this data-structure. Of course, it´s possible for me to implement some program that will transform the Excel-File into an xml etc.. As part of the tool-evaluation I want to focus on following aspects:

Basic ERM is actually how I got into Dia

• Support Windows: yes / no
• Support Notation Barker: yes / no
• Support Notation Martin / Crow´s Foot: yes / no
• Import Excel-Format (incl. csv, xml):
• Link – structure Excel:
• Export Image-Format (PDF, JPEG, PNG, …):
• Reverse Engineering: yes / no
• Identify / Show changes after update data-set: yes / no
• Supported Import-Formats:
• Versioning: yes / no
• Multi-User-Access to one project: yes / no
• Trial available: yes / no
• Price (in runtime x for organizations) : x€
• License type:
• Running costs (e.g. for support): x€
• Programming skills neccessary? : yes / no

Not sure what this list is about?

These should be the content of the future ERM (semi-/automatic generated):

• Entity-names – possible: yes / no
• Relationship-names (next to arrows) – possible: yes / no
• Generalization / Specialization of entities– possible: yes / no

I haven´t found all information on your website. That´s why I´d kindly like you to give me an answer to all of these “feature requestes”.

Well our 'website' is an interesting problem..... Have you tried using dia? I suspect that would answer quite a few of your questions

 

Thanks a lot!

 

 

Best regards,
