Rdb is undoubtedly the most important among those using VMS today.

But VMS should hopefully grow beyond who are using VMS today.

For a certain market segment then Oracle DB (Oracle classic) is
very important.

But:
1) Oracle may be difficult to persuade to change strategy (they are
    a huge company and VSI is a small company).
2) There are other market segments than those willing to pay
    a 5 digit dollar amount per core for database licenses.

Available relational databases on VMS include:
* Rdb
* MySQL/MariaDB
* SQlite
* Mimer
* HSQLDB
* H2
* Derby
