Database normalization is the cornerstone of database theory. Once a database is normalized, relationships between the data in multiple tables must be established.

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

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.

With a relational database, you accomplish this by way of new data columns (for one-to-one or one-to-many relationships), or new tables (for many-to-many relationships).
