[Oracle SQL Developer is] best suited if your company works with different databases and needs a common SQL editor to manage and query data for its user. Oracle SQL Developer works very well with Oracle but also some other relational databases. If you do lot of querying and import/export in database, then this is tool for you. It's ideal for DBAs as well for data modeling, management, session monitoring, logging, versioning, etc. It’s not ideal for no relational/noSQL or big data. It is not tool for visualization. It’s best suited for querying using SQL. Companies that are looking for free tools that are robust and most useful should definitely look at it.
