Databases play a huge role in a large number of Web sites. Companies frequently keep product information, orders, schedules, and even technical support information in databases. Databases take much of the hassle out of storing and retrieving data. You don't have to worry about converting an object into a string to store it in a file, or using object serialization (unless you store serialized objects in the database). Instead, you get to worry about things like connection pooling and transactions.
