Strongly agree with others here that you skipped better options.

Also, since time immemorial, databases are cylinders and data comes in cubes.

For logo purposes, these are both strong, while the second adds “personality”:

I really like the design breaking out of the strong circle, and your hard hat idea was great. That last one could have been your logo “as is”!

Though you could consider replacing the green cubes with cylinders, or simply hand add rubix cube lines to these green cubes to make them data cubes.
