Find the data you need
Start with the schema, narrow the search, and see how the likely tables relate before writing a query.
The problem
When you open an unfamiliar database, where does the data you need actually live?
A familiar business concept rarely has a familiar table name. Customer details may sit in one table, purchases in another, and the key that joins them may be undocumented. Guessing from names or opening tables one by one slows down every new investigation.
A clearer workflow
Orient yourself
Browse the source and inspect its tables, columns, and available relationships.
Follow a clue
Start with a business term or a known identifier, then inspect the fields and adjacent tables that look relevant.
Check with data
Preview records or run a small query to confirm that the table contains the answer you expected.
What changes
You leave with a specific table, field, and relationship to use, instead of a guess about where to begin.
