Web Databases

Since the inception of the Internet, we have seen the capabilities of this worldwide network grow from basic text pages to elaborate marketing-based Web sites, to online shopping centers. In each case, the technological capabilities behind the Internet have increased vastly to accommodate each new type of Web site. Most recently, many portions of Web sites have been controlled by databases. With databases, site visitors can query the most recent information from a site as well as contribute new information. For instance, the most elaborate shopping sites on the Web require database connections in order to query current stock for products as well as allow the user to order a specific item.

As you probably can guess, databases are everywhere that computers exist. Computer systems need to store vast amounts of information for purchase orders, product inventory, personal contact information, and just about anything else you can imagine. A database management system (DBMS) is required in order to store large quantities of data. With a database management system, large quantities of information can be stored on a single computer or even distributed across multiple systems. It is up to the database management system to understand how to best store information and optimize that storage. By optimizing the storage of data, a DBMS can quickly and easily perform searches on information within the database and return accurate results.
