Thank you very much for your reply.
Yes I am installing talend open source MDM server. as your shown in the link, could I understand that other db is not supported by the open source edition MDM server?
And I have another question about where can I get Administration Center, I can't find any information on the talend site.
The community edition only provides H2 as SQL database.
Talend Administration Center is only available in talend subscription solution not open source.
What we can do is to make sure that Talend will be your best choice!
