Hi Feras,
Here are the storage options which are supported by Google Cloud Platform. Each of these products has dashboard, and logging is provided for them. Furthermore you may find some useful information on how to querying data stored outside of BigQuery through this link.
For any support on the aforementioned storage options, I need more details and clarification. What and where is your database? Is it a local one? What kind of reports do you need? What elements do you wants to drag and drop?
Your questions seems to be more related to Firebase rather than Google Cloud Platform-end products. If so, I recommend that you ask your question in the Firebase community.
