Where are the SQL development tools for the Eclipse IDE and Spring Tools Suite? Why are they seemingly unavailable in their marketplaces?

Question

I'm learning the Java Programming language and Spring, and when I try to follow some online tutorials or projects related to Spring technologies, I keep getting stuck whenever I need to create a new SQL file or a SQL database WITHIN the Eclipse IDE or Spring Tools Suite. I'm simply unable to do so, and while various solutions online simply give instructions to "search and install the SQL development tools or SQL editor from the Eclipse Marketplace", I am not able to find the SQL development tools, while the SQL editor is a very basic thing with no development facilities. So WHERE can I find the required tools/extensions for creating & running SQL files, databases, etc, on the Eclipse IDE or Spring Tools Suite? Also, are there any alternative extensions/add-ons that have the SQL development capabilities? I would be really grateful if someone could answer.

I am a little bit unsure if it is exactly what you're looking for, but Data Tools Platform is the one i've been using in the past to manage DBs:
