Excel possesses formidable database powers. Creating a relational database starts with a Master table that links to subordinates called (awkwardly) Slave, Child, or Detail tables.

Are you still putting your data in plain, old spreadsheets? Excel 2013 makes it easy to link tables, create reports and more.

Strong analytical skills also help database developers design applications efficiently; for example, tables in many databases often have keys that link one table to another, removing redundancy.
